Brief description of the drawings
The electronic map screen display schematic diagram of the quick estimated distances of Fig. 1.
In figure：1. display screen, 2. linear scales, 3. screen width AB, L are corresponding screen is wide with screen scaling
The horizontal range on the spot corresponding to AB is spent, MN is straight long route on the electronic map, and N ' is the M and A during map scaling
The position of N points during coincidence.
Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Example 1
As shown in drawings, the horizontal range on interpretation display screen 1 between map M, N point is intended.
First method：Using the existing method before the present invention.With screen scaling, the label length of linear scale
It is almost unchanged, but signal quantity correspondence changes the linear scale correspondence shown thereon on the spot.Map scale becomes big, straight line ratio
Example chi becomes accurate.But engineer's scale mark seems very small compared with screen size, all the time.Fig. 1 is schematic diagram, actually directly
The size of bar scale is also much smaller.Therefore the straight long routes of MN on the electronic map can only be come by the length of linear scale
Proportion.Not only time-consuming bothersome, the eyes pain of glance, clock more than 3 points also can only be with eye estimate probably.Moreover, 6 ginsengs add experiment,
Total time-consuming is more than 6 minutes, and 6 result differences quoted are very big, and exceedes desired error range.
Second method, using the inventive method, its interpretation process is as follows：Because the line of M, N point is favoured electronically
Figure length direction, by translating map, makes the M points of the south coincide with the southwest corner A of display screen；By scaling map, make MN's '
Length is equal with the width AB of display screen, all the time the mark on the linear scale 2 of distance on the spot corresponding with display screen width AB
Note changes for 28100 meters immediately apart from quantity L.The as horizontal range on the spot of MN point-to-point transmissions.It is all according to AN ' and AB in scaling
Circular arc is drawn as the radius in the center of circle using A and judges whether both are equal to facilitate.In experiment, 6 people participate in experiment, and total time-consuming 1 minute is complete
Into the result quoted is in prescribed limit.
More than experiment shows, the map by Pan and Zoom, make the beginning and end of distance respectively with electronic map
A pair of length or width are combined and are equal, and directly read corresponding length or wide mark numeral can obtain horizontal range on the spot.This
Invention is exactly this concept of schematic diagram and intrinsic prejudice by the linear scale just existed always since changing map invention,
The problem of distance transform is set to be readily solved, the purpose of distance can directly be read by reaching.
For the route parallel to electronic map length or width, Pan and Zoom map, make distance starting point and
Terminal connects with the long side of electronic map or broadside respectively, directly reads corresponding length or wide mark numeral.
The above method is suitable for the situation that route is straightway, for route it is not straight extended or staged operation i.e.
Can.
Example 2
Traditional map scaling method and the inventive method are compared as follows：
Existing map orientation orientation, exactly makes the Shang Bei of map, Xia Nan, Zuo Xi, right east position consistent with orientation on the spot.2015
The Hu Yunda chief editors that January in year, publishing house of Wuhan University published《Military topography and orienteering》Described in the second edition traditional
Four kinds of scaling methods of map.First method is demarcated for outline.This method is simple, convenient and rapid, but must be clearly existing local
Position.This is in the strange landform of no compass, and it is difficult to accomplish that constellation, the night without physical feature are not seen particularly.Second
Method is demarcated for compass, but can not be realized during without compass.The third method is to utilize straight long atural object demarcation.Desert and Gobi is very
Difficulty finds this condition.4th kind of method is to utilize the demarcation of obvious place.Must equally possess corresponding conditionses.
The inventive method：When entering electronic map calibration mode, display is automatically performed by electronic map with dipper system
Demarcation, when display screen shows residing direction, then electronic map Shang Bei, Xia Nan, Zuo Xi, right east are consistent with orientation on the spot.No matter it is aobvious
How display screen direction changes, and above-mentioned demarcation state will not change, and electronic map is firmly locked just as floating on a display screen
Fixed existing place to.
By above example as can be seen that the present invention solve user now can not find it is northern, isotropic especially strange
The problem of region is advanced by figure；Change people and defend tenaciously the prejudice that engineer's scale is linear scale schematic diagram, interpretation for many years
Apart from efficiency high；By free-hand zooming and panning map, user obtains enjoyment from control sense；By map automatic Calibration, plus
Deep impression and impression of the user to existing ground topography and geomorphology, improves the affinity of man and nature topography and geomorphologies.
