JP2589336B2 - A device for exploring details on a map or street map - Google Patents

Description

Description: FIELD OF THE INVENTION The present invention relates to an apparatus capable of quickly exploring the position of details presented on a map or a street map as information material.

BACKGROUND OF THE INVENTION Such devices are used, in particular, for reading maps or street maps. A grid is usually provided on the map or street map to narrow the search area for map users. These maps include a number of horizontal and vertical lines marked with numbers or letters for more accurate identification purposes. The indices on the map indicate the coordinates of the extent of the grid with respect to the location of each detail (eg, street or location). The search for details is therefore narrowed with respect to area. Retrieval is still relatively time consuming, especially because the grid cannot be drawn too narrowly on a map segment for clarity, especially when numerous details are in each area of the grid. When located, it takes time to search.

For decades, attempts have been made to overcome the shortcomings as described as much as possible, indefinitely.
In this case, we follow the principle of using a finer grid on the map to go from the larger part to the details, but do not show this directly on the paper of the map.
On the contrary, it is known that the easiest thing to do in this regard is to be able to place a film sheet with a fine grid on the paper of the map. However, such variations are inconvenient for the map user, as are the grids printed directly on the map. Regardless of whether details can be identified, efforts to search for details continue with little loss due to lack of clarity.

Further, as a solution, for example, U.S. Pat.
899 / DE-U-7922749 and U.S. Pat.No. 2,891,3
As is known from the specification of US Pat. No. 14, some have provided only a fine scale of the edges of the map in order to overcome the disadvantages that still exist. The displaceable member along these edges and the intersection of the two components allows the precise determination of the details. Indices of the map are provided in parallel with these edges, and the coordinates of the positions searched can be known from the indices. The disadvantage of these solutions is that they generally require a frame that is applied around the edge of the map. In addition, the cartographer must change the way the previous grid distribution and also the coordinates for the details are shown. Users of the map
Sequential changes have to be made from conventional modes of use, which complicate such solutions.

The disadvantages of this type can be mitigated by retaining a conventional map grid and making finer grading only for each of the individual areas of the grid, for example, as in FR-A-2258679. However, this requires extending the previous two digit coordinate reference to four digits. This adds complexity to both cartographers and map users. In addition, a device that covers only one area of the grid for the map cannot ensure satisfactory detail, i.e., once a location is found, it is not possible during the desired time interval, especially in a motor vehicle. Cannot be fixed.

For example, devices such as those described in DE-A-2849648, DE-A-1900536 or US-A-2516569 are better in this regard. In them,
It uses elements of a fine grid that protrude sufficiently beyond the sections of the map, and on which the slides are placed. Once a point has been found, the device is fixed in this way for the slide during the desired time. The disadvantage of these solutions is that two-digit coordinate references are customary in map indices and that a search is still required for details in a given area of the grid, or on the other hand, relatively Either the criteria will be large, the disadvantages have already been mentioned.

After all, the details searched for should be said to be both points and wide different areas (eg, streets). With known solutions, it is possible to have the correct features of the contour only with regard to the clarity of the details in the form of points. This is not the case with regard to the clarity of the area. For example, as described in DE-A-1900536, the placement of a window-like opening in a slide makes it possible, as long as the window-like element is provided above and below the sliding element, between the two possibilities of clarity at this point. Is only considered to be in the middle of this, and this again requires a separate search for details inside this window, and in addition the determination covered by the window element The results obtained, even if they are made of transparent materials, must be accepted. This reduces clarity and, as disclosed in DE-A-1900536, results in a relatively time-consuming retrieval of details by this type of device.

In summary, the use of previous solutions could not keep the cartographer's expenses within justified limits, and at the same time could be deemed simple by the mapper It can be said that the method could not be secured. Therefore, map sets, which in principle comprise auxiliary devices for exploring details, have hitherto not been available on the market.

It is therefore an object of the present invention to provide an apparatus in which details in a map set are quickly explored. In this case, the expense of the cartographer is low, and the use of the cartographer is simplified as a result of a small coordinate reference at the location of the details. In addition, it is possible to explore details precisely in both point and area form.

The above objects of the invention are achieved by an apparatus for exploring details on a map or street map having the features of the claims.

Means for Solving the Problems The present invention is based on a map set having a conventional large grid on only one edge. To simplify the explanation,
It is assumed that this edge extends horizontally along the upper edge of the map. The guiding gauge base, whose width corresponds to at least one scale on a large scale, and whose length vertically surrounds the map, can be firmly clamped on the upper edge of the map. The gauge base has a scale along its longitudinal extension.
A sliding member provided as a base is arranged on the base and covers over its width and can be moved along its scale. The marking line and the scale have the same scale as the scale of the scale provided on the gauge base, and are provided on the sliding member in the horizontal direction. The width of the sliding member has its dimensions so that the marking line can be matched to each mark on the gauge scale of the gauge base.
Furthermore, a sliding element may be used as a bar member and provided on a base that is a sliding member to provide a line for marking. The shape of the bar with respect to the sliding member is adapted to be similar to the position of the sliding member with respect to the gauge base, i.e., can be adapted to correspond to each section of the scale graduation of the sliding member, for marking. Lines are shown on the bar members.

The scale graduation on the gauge base or in the direction of travel of the sliding element, and the resulting or scale graduation of the sliding element is so narrow that the rectangle formed by this section is the smallest detail that can be retrieved in the map and the dimensions and map set in that area. It is made comparable to the area.

With the aforementioned individual parts arranged in this way, 2
It is possible to indicate the location of each detail on the map covered by the gauge base with one coordinate reference. In this case, it is a precondition that all of the individual components are made transparent.

The indices as applied to the map set are such that the details to be explored are raised in a conventional manner, and in addition to the criteria relating to the respective scales of the gauge base and the sliding element, simply indicate on the upper edge of the map. It only needs to include an indicator for the junction of the base. If the identified detail is larger in that area than the rectangle (eg, a street) formed by the smallest scale, a coordinate reference is then associated with the center of the detail.

The present invention is described in more detail with reference to the drawings, which show a top view of a street map, with the device placed thereon.

EXAMPLE A map set has a conventional large scale 11 on its upper edge 37, mainly with reference to FIGS.
The details to be explored are defined as B10 / f, a map index criterion in which “Neuer Wall” relates to the center of the details. The first numerical reference is set to the gauge base 32 or the sliding member. This means that a line 18 for marking provided on the base 20 which is a sliding member is converted into a numeral base 10 of the gauge base 32 or the scale 14 of the sliding member by the displacement of the sliding member, that is, the base 20. Implemented by matching. To set the second numerical reference now required, a bar (not shown) is mounted on the base, i.
The upper part is displaced until the marking line 17 provided thereon coincides with the numerical reference f on the scale 13 of the sliding element. In this method, the lines 18 and 17 for marking are the intersections defined by the coordinates 10 / f
Crosses at 19. Gauge base 32, sliding member 20
After the individual parts constituted by the bar and the bar members have been moved into this position, the gauge bases 31 and 32 are
It only needs to be positioned flush with the edge 37 of the map at one point B. The details to be explored are located at the intersection 19 of those lines immediately at the center of the area.

The gauge base 32, the slide base 20, and the bar members are preferably made from rigid sheets of film.
All of these parts have clamping folds on the sides that delimit their length. This means that the gauge base 32 is tightened on the upper edge 33 of the map,
20 is a sliding member that can be moved on the gauge base 32
It is possible to arrange the rod 20 so that it cannot be pulled out of it and cannot be pulled away, and the bar can be arranged so that it can be displaced on the sliding member 20 and cannot slip off. The scale graduations 14 and 13 are provided in a known manner on the rigid film material of the sliding member 20 and the gauge base 32 of the bar in the same manner as the lines 18 and 17 for marking.

In the device as described in this embodiment,
The changes made by the cartographer within the limits are still possible, i.e., the author gives a large scale to one edge 33 of the map and otherwise specifies each coordinate normally two coordinates. It is simply necessary to indicate them by index. For map users, the setting of coordinates is simple and very different from conventional procedures in searching for details defined by the next join to a large scale of the map. Absent. The search itself, within its scope, requires only the handling of two settings and the joining or suspension of the gauge base to explore the details. In addition, the device makes it possible to explore details in both point and area form with substantially equal precision. Moreover, once a location has been found, the exploration can remain fixed for a desired length of time.

As well as using this device for maps and street maps,
It can also be used to explore details, for example in technical drawings or paper patterns.

 Further, the details of the map set will be described below.

As shown in FIG. 1, an exploration device having an indicator unit 1 which is a sliding member moves horizontally on a street map 2 serving as information material on a flat sheet with respect to a vertical direction of the street map. It is arranged to be able to do. The display unit 1 is provided in a form having a shape of a thread that can move along the lines 3a, 3b, and 3c. These lines 3a, 3b, 3c are set by a large grid 4 printed on the street map 2 and have these lines 3a, 3b, 3c at approximately equal intervals, these lines defining the grid ing. These lines 3a, 3b, 3c extend substantially horizontally and intersect the vertical lines 5a, 5b, 5c, 5d. Horizon 3
a, 3b, 3c are substantially perpendicular to the vertical lines 5a, 5b, 5c, 5d. Between the four intersecting partial lengths 6, 7, 8, and 9, one grid square 10 of the street map 2 is set.
These grids 10 together form a large grid 4. Each grid cell is represented by a scale reference numeral 11,12, one of which is a mutually perpendicular one.
For the reticulated grid 10 and other reference numbers 12
Are for grids 10 arranged horizontally with respect to each other. For example, for grids arranged vertically with respect to each other, the uppercase letter of the alphabet is used as reference numeral 11, while Roman numerals are used for grids 10 arranged horizontally.
Used as reference numeral 12.

The lines 3a, 3b, 3c, 5a, 5b, 5c have scales 13,14. The scales of the horizontally extending lines 3a, 3b, 3c are, for example, lowercase letters, while the vertically extending lines 5a, 3b,
The scale 14 of 5c is made up of Arabic numerals and has the same scale width. These graduations 13, 14 can be arranged such that their corresponding counts start from the beginning of each grid 10. Therefore, the partial lengths 6, 7, 8, 9 of the lines 3a, 3b, 3c, 5a, 5b, 5c, for example, start with the lowercase letter "a" in the horizontal direction and the number "1" in the vertical direction Can start with If the partial length 6,7,
If 8, 9 are of the same size, the scales 13, 14 end with a number or letter, for example "m" or "13".

The display unit 1 has at least one horizontal line 3a, 3b, 3c.
Is movably arranged along. Detail 1 on street map 2
5, for example, if the “Neuer Wall” is to be explored, place the letter “g” on the scale 13. In this way, the position of the required detail 15 can be searched along the display unit 1. This required detail 15 is determined at a specific location on the display unit 1. All details 15 of the street map 2 are included in a list not shown. This list not only contains the symbols 11, 12 of the large grid 4 for each detail 15, but also includes graduations 13, 14, by means of which the position of the detail 15 can be quickly explored. In this regard, it is conceivable that the scales 13, 14 of each grid square 10, for example as shown in FIG. 1, start with the letter "a" or the number "1". However, for the lines 3a, 3b, 3c, 5a, 5b, 5c, the symbols are selected to be continuous along their length extending through the whole street map 2 and the graduations 13, The 14 can be made to begin with a letter or digit following the last letter or digit of the grid 10 before the grid. Depending on the size of the section 16 of the street diagram 2 to be examined, only the symbol of each line 13, 14 extending along the edge of the section 16 is sufficient. In this case, the display unit 1 needs to be long enough to extend across the entire section 16. However, if each grid 10 has at least a partial length 6,7,8,
When the graduations 13 and 14 are provided at 9, it is sufficient that the length of the display unit 1 corresponds to the size of the grid 10. The advantage of shortening the display unit 1 raises the problem of reducing the clarity of the street map 2. The reason for this is that the number of scales is large.

In order to accurately determine the position of the required detail 15, the indicator unit 1 is actually provided with two intersection lines 17,1 for marking.
It has a cross mark formed by eight. 1
The lines 17 are arranged so that they extend vertically and can move along a horizontal scale 13, while the other lines 18
Are arranged so as to be able to move along a horizontally extending and vertically extending scale 14. Activation of large lattice 4 11,1
Since the two and the scales 13, 14 are arranged corresponding to the required details 15 in a list (not shown), the intersection 19 formed by the lines 17, 18 lists the vertically extending line 17 The search can be made directly by moving to the point indicated in the table, for example the letter "g" on the scale 13, while moving the horizontally extending line 18 to the designated point on the vertically extending scale 14. In this way, the required details 15 are accurately represented by the intersection 19. In this case, in the list (not shown), the arrangement of the symbols 11 and 12 or the scales 13 and 14 are obtained for the details 15, and, for example, in the case of a street, the arrangement obtained from the list is selected to obtain the intersection. 19 can be adapted to be located approximately in the center of the street extending through section 16.

Further, as shown in FIG. 2, the scales 13 and 14 can be provided on a base 20 which is a sliding member that touches the street map 2. For practical reasons, the base 20 is sized to correspond to the dimensions of each grid 10. The lines 17 and 18 for marking are movably disposed on the base 20. The base 20 is arranged so that the edges 21, 22, 23, 24 defining it extend along the partial sections 6, 7, 8, 9 of the grid 10. In this way, the lines 17 and 18 correspond to the scales 13 and 1 of the base 20 according to the information obtained from the list (not shown).
4 You will be able to move up.

For practical reasons, the base 20 is formed as a magnifying glass.
The base can be, for example, a transparent plastic magnifier. By making the structure of the base 20 in this way, the location of the small details 15 can be accurately probed from its location on the street map 2.

The base 20 can still be made up of three layers 63, 64, 81 which are vertically stacked on one another, as shown in FIG.
Voids 65, 66 are provided between these layers 63, 64, 81, and one side of each of these voids has a lower end surface 74,
75 and the upper end surfaces 82 and 83 of the upper layers 81 and 64, respectively. These end faces 74, 75 and 82, 83 are substantially parallel to each other. The gaps 65 and 66 are respectively upper end faces 82 and 83
And the upper and lower end faces 74 and 75 for marking lines 17 and 18
Has enough distance to move the rod member for providing the pressure in the gaps 65 and 66. The upper end surfaces 82 and 83 and the lower end surfaces 74 and 75 that define these gaps 65 and 66 extend substantially parallel to the bottom surface 84 when the base 20 is placed on the street map 2.

Each of the layers 63, 64, 81 is held in place by spacing members 67, 68, 69, and one of such spacing members is formed at each corner 70, 71, 72 of the base 20 formed into a rectangular shape. , 73. In this case, the spacing member is, for example, a steel bolt, which is passed through the through holes in the corners 70, 71, 72, 73, and is screwed to the layers 63, 64, 81 which can be separated from each other. Can be. By making the structure of the base 20 in this way, as long as the layers 63, 64, 81 can be separated from each other,
The advantage is obtained that the end faces 74, 75 and 82, 83 can be formed inexpensively. However, the base 20 has three layers 63, 6
Formed as a block containing 4,81, and the gap 65,66
Can be considered in the form of a slit in the block. In this case, it is important that the end faces 74, 75 and 82, 83 be carefully formed so that the entire block forming the base 20 remains transparent and through which the street map 2 can be observed. In practice, the block has an arcuate surface 85 opposite the bottom surface 84 such that the base is a magnifying glass for enlarging the detail 15.

If the cavities 65, 66 are in the form of slots, they can extend perpendicularly to each other through the blocks that make up the base 20. The width of each slit is base 20
And the layers 63, 64, 81 are interconnected by edge sections extending on both sides of each of the two slits. In this case, it is not necessary to provide the spacing members 67, 68, 69.

In any case, the width of the slit should be selected to correspond to the dimensions of the grid 10. In this way, the viewing section can be maintained between the edge sections or spacing members 67, 68, 69 of dimensions corresponding to the grid 10. Therefore, when the base 20 is placed on the grid 10
The edge compartments or spacing members 67, 68, 69 of each slit are grid 10
It must be formed so as to be located outside the.

The mutually parallel grooves 76, 77 pass through the upper end surfaces 74, 75, and the gaps 65, 6
Lines 17, 18 for marking on bar members extending through 6
It extends toward. In these grooves 76 and 77, the lines 17 and 18 are
It has a sufficient cross section to pass through 6,77. One void
The groove 76 at 65 extends at the same angle as the line 3a, 3b, 3c, 5a, 5b, 5c defining the large grid 4 with respect to the groove 77 at the other gap 66. Normally the grooves 76, 77 are located at different levels, but can extend at right angles to each other. In this way, the lines 17 and 18 extend exactly through the gaps 65 and 66 independently of each other, and thus,
Can be read correctly.

As shown in FIG. 4, the guide 32, which is a gauge base, extends through the street map 2 and extends, for example, from an upper edge 33 extending in a horizontal direction to a lower edge 34. It can be configured to limit at opposing ends. This guide 32 is, for example, two rails 35, 36,
The rails can extend substantially parallel to one another and extend across the street map 2. The two rails 35, 36 are interconnected by transverse connecting members 37, 38, which extend substantially parallel to the upper edge 33 and the lower edge 34.
The distance between these rails 35, 36 can correspond to the distance between two vertical lines 5c or 5b. However, the distance between the two rails 35, 36 can be chosen differently. The rails 35 and 36 are arranged along the upper edge 33 and the lower edge 34 so as to be able to move laterally with respect to the vertical direction of the rails. Thus, these rails can move horizontally across the entire street map 2.

The base 20 is disposed on the rails 35 and 36 so as to be movable in a direction perpendicular thereto. In this case, not only the scale mark 13 but also the scale mark 14 provided on the guide 32 of the rails 35 and 36 is provided on the base 20. The lines 17, 18 for marking can be moved along these scales 13, 14. According to the present invention, the base 20 can be relatively accurately positioned on the street map 2 according to this embodiment. Undesirable movement of the base 20 with respect to the street map 2 is conveniently prevented. The reason is that there is no possibility that the guide 32 slides unexpectedly along the upper edge or the base 20 moves unexpectedly along the rails 35 and 36. The base 20 movably seated on the rails 35, 36 can be according to some of the embodiments described above. As shown in FIG. 5, the base 20, which is a sliding member, has an upper edge 31.
Alternatively, a graduation 13 having vertical lines 29 and 30 corresponding thereto and a horizontal line 15 at the center may be used.

A gauge-based guide 32 extends vertically or horizontally across the street map 2. Further, as shown in FIG. 6, the guide 32, which is a gauge base, has a ruler 39 disposed along the corresponding edge 40, 41, 42, 43 with respect to the street map 2.
In the form of This ruler 39 is formed of a transparent material. The base 20, which is the sliding member, is movably disposed on a ruler. The base 20 can be formed of a frame 25 or a transparent material surrounding the open space 28 shown in FIG. Both the ruler 39 and the base 20 can be formed as magnifiers. In this case, the base 20 can be provided with fine scales 13, 14 along the edges 21, 22, 23, 24 as described above. Lines 17 and 18 are movably arranged along the fine scales 13 and 14.

As shown in FIGS. 6 and 7, only one line 44 may be provided on the base 20, and this line may extend in the horizontal direction with respect to the vertical direction of the ruler 39. More ruler
A thin line 45 is engraved on 39, so that the thin line extends parallel to the longitudinal direction of the ruler 39. This thin line 45 has at least one symbol 46 at its end corresponding to the fine graduation 14. The ruler 39 is preferably made to have a width equal to the width of one square 10. Further, the ruler 39 has a fine scale 47 extending in the vertical direction. This fine scale 47 corresponds to the scale 13 and has a partial line 48.
Each of these partial lines can be matched with a line 44 engraved on the base 20.

The ruler 39 is as shown in FIG. Depending on their arrangement, they can be moved along the vertical edges 41, 43 or the horizontal edges 40, 42 until they correspond to the symbols 11 or 12 of the large grid 4. These symbols 11 and 12 are a list (not shown)
It is related to the details 15 required within. Next, the base 20 is moved in the vertical direction of the ruler 39 until the line 44 is aligned with the partial line 48 of the scale 47. In this way, the position of the desired detail 15 can be searched for along the line 44. This detail is located on one of the thin lines 45,
The symbol 46 is obtained from a list (not shown).

However, the ruler 39 can be without the thin wire 45. In this case, the ruler 39 merely acts as a guide for the base 20, which has lines 17, 18 for markings which can be moved thereon. In this case the base 20 is gridded for all practical purposes.
Its edge 2 having dimensions of 10 and as shown in FIG.
There are corresponding scales along 1,22,23,24.

To support the guide 32, which is a gauge base, guide edges 49, 50 can be provided which extend along said edges 40, 41, 42, 43, as can be seen in FIG. These guide edges 49,
50 is an open box having a bottom 52 similar to the base for the street map 2
51 can be defined. The bottom 52 is limited at its two opposite ends by walls 53, 54 containing the bottom at substantially right angles, and on the upper side opposite the bottom 52 are provided guide edges 49, 50. To further reinforce box 51,
As shown in FIG. 4, horizontal walls 55, 56 can be provided, which define a box 51 in a direction transverse to the longitudinal direction of said walls 53, 54. Street Map 2 shows walls 53 and 54 and side walls 55 and 56
Is positioned between

The gauge-based guide 32 is moved across the street map 2 within the guide edges 49,50. For this purpose, a guide 32 is provided at one of its ends, as shown in FIG.
It has a guide groove 57 extending through 49. This guide groove 57
Extends in the form of the letter U over the guiding rim 49 and engages with a retaining member 59 by means of its end 58 located outside the box 51, which retains the wall 54 outside the box 51. And extends in the longitudinal direction of the wall 54. The end 58 extends inside the holding member 59 and thus prevents the guide edge 49 from slipping out of the guide groove 57.

The guide groove 57 extends over the guide edge 49 and has a yoke 60 at its yoke 60 with a pivot hinge 61 extending along the guide edge 49. The guide 32 is pivotally supported on the pivot hinge 61. The guide 32 can pivot away from the street map. Thus, the street map 2 can be inserted into or removed from the box 51. The pivot hinge 61 is arranged to ensure that the guide 32 touches the street map 2.

The guide 32, which is the gauge base, may have a guide groove 62 at a position shown in FIG. 6 at an end thereof facing the wall 54. This groove 62 extends over the guide edge 55. However, the guide 32 is guided by the guide groove 57
It can be made to sit on 49.

Street map 2 is clear from FIGS. 4 and 7,
It is inserted into the box 51. Usually a collapsed street map is used, on which the required details 15 are located between the walls 53,54 and the side walls 55,56. If necessary, for the street map 2, a box is selected that is large enough to put the entire street map in box 51.

Next, the gauge-based guide 32 pivots about the pivot hinge 61 to ensure that the guide 32 is seated on the street map 2. Then, from the list (not shown),
Determine in which grid 10 the desired detail 15 is located. Guide 32 according to the information requested from the list
To the grid 10 located vertically below. This square symbol 11 is read from the list. Next, the symbol where the base 20 is located is obtained from the list. However, if the fine line 45 extends across the entire ruler 39, it is not necessary to read the symbol 12 for the large grid 4. Instead, the symbol 46 for the thin line 45 and the line 44 engraved on the base 20
Needs to be obtained from the list. If the base 20, which is a sliding member, is moved on the above 39 so as to correspond to the scale 47, a thin line having a symbol 46 is obtained.
The required detail 15 can be found at the intersection of 45 and line 44.

Finally, the details 15, symbols 11, 12 and graduations 13, 14 can be stored in the computer 78 shown in FIG. The details 15 are stored in this computer 78 by their properties, for example their first letters. Detail 15 is computer 78
Can be called by the keyboard 87. In this way a detail 15 with associated symbols 11, 12 and graduations 13, 14
Appears on the screen 88.

The computer 78 has a control line as shown in FIG.
Through 89 and 93, it can be connected to a servomotor 79 which drives the guide 32 which is a gauge base. The guide 32 can be movably arranged, for example, on a rack 90 extending over one of the guide edges 49. The rack 90 has its teeth
91 is arranged in the direction of the horizontal connecting member 37 of the guide 32. The pinion 92 is pivotally disposed on the transverse connecting member 37 and has its teeth extending into the rack 90. This pinion is driven by a servomotor 79 mounted on a transverse connecting member 37 which, in accordance with the details 15 called out from the computer 78, carries a guide 32, on a guiding rim 49, a guide 32. Until it is over the detail 15.

Further, the computer 78 is connected by a further control line 93 to a drive motor 80, which moves the base 20 along the guide 32, which is a gauge base. In response to the detail 15 called from the computer 78, the base 20 is moved along the guide 32 until the intersection 19 fixed on the base 20 is positioned directly above this detail 15. In this way, not only the relation between the symbols 11 and 12 or the scales 13 and 14 and the details 15 can be determined through the computer 78, but also the position of the details 15 can be determined by the control signals generated in the computer 78. 2 so that it can be searched. Of course, in this case, it is not possible to omit accurate alignment of the street map with the guide edge 49.

The device described above can be used for street maps and maps of any size. The device can also be used when searching for the location of other details 15, for example when searching for a detail 15 from a work drawing whose position has been accurately determined with respect to a section of the drawing.
