Abstract
The invention discloses a kind of contours to be segmented mask method, belongs to mapping, technical field of geographic information.This method generates contour first with DEM by certain contour interval, then a series of square grid of area equations is generated using Create Fishnet tool bars in ArcGIS, reuse the included Intersect tool bars of ArcGIS, the square grid face figure layer of generation and contour figure layer are subjected to intersection operation, contour is split according to equidistant, and retains the attribute of former contour after dividing.When showing that contour marks attribute again, the mark of contour is according to equidistant display.The method of the present invention is easy to use, is easy to realize in ArcGIS.
Description
Technical field
The present invention relates to a kind of methods to contour line attribute segmentation mark, belong to mapping, technical field of geographic information.
Background technology
In ArcGIS (Geographic Information System, GIS-Geographic Information System), a certain figure layer category is shown
Property mark main three kinds of mode, one is the attribute for not showing repetition, another kind be each element place one mark, also
Have one is each element part place one mark.But since the length of contour is bigger, if a contour is only
As soon as place a mark, searched on derived map a certain longer contour of length etc. high level when require to look up
For a long time, thus need segmentation mark is carried out to the attribute of every contour.
Invention content：
The drawbacks of showing is marked to contour line attribute in ArcGIS, the present invention proposes a kind of attribute to contour
The method for carrying out segmentation display mark.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of contour segmentation mask method, is divided into several sections, every section by contour according to the size of the grid in grid face
Attribute labeling is carried out respectively.
Preferably, grid face figure layer is regular square grid face figure layer.
Preferably, it the present invention is based on ArcGIS realizations, is as follows：
1. surface analysis (Surface) the tool bar Contour (contour) using ArcGIS is (digital to the DEM of selection
Elevation model is to calculate the earth's surface elevation distributed data to be formed by space interpolation with discrete elevation point) according to certain contour interval
Generate contour.
2. using the factor kind of the data organizing tool item (Data Management Tools) of ArcGIS below
(Feature Class) generates fishing net (Create Fishnet) tool bar, and formation range is consistent with contour range, and sets
Set the face figure layer of element size determination.
3. using the Overlap Analysis (Overlay) of the analysis tool item (Analysis Tools) of ArcGIS below, interrupt
(Intersect) size for the cell that tool bar generates contour according to previous step does not change former contour into Break Row
Attribute.
4. set a property mark.It sets element attribute labeling to mark each section of element, you can by contour according to net
The size of lattice carries out segmentation display mark.
Advantageous effect：Present invention realization carries out segmentation mark to the attribute of every contour, and easy-to-look-up length is longer
Contour etc. high level；The method of the present invention is easy to use, is easy to realize in ArcGIS.
Description of the drawings
Fig. 1 is contour segmentation mark figure；
Fig. 2 is contour map；
Fig. 3 is grid face figure layer.
Specific implementation mode
Further explanation is done to the present invention below in conjunction with the accompanying drawings.
Certain urban parts DEM is now chosen to be described in detail.
1. using surface analysis (Surface) the tool bar Contour (contour) of ArcGIS to the DEM of selection according to 50
Rice contour interval generates contour.As shown in Figure 2.
2. using the factor kind of the data organizing tool item (Data Management Tools) of ArcGIS below
(Feature Class) generates fishing net (Create Fishnet) tool bar, generates the consistent regular square of contour range
Grid face figure layer, grid size are 200 meters, as shown in Figure 3.
3. using the Overlap Analysis (Overlay) of the analysis tool item (Analysis Tools) of ArcGIS below, interrupt
(Intersect) grid that tool bar generates contour according to previous step is into Break Row.
4. set a property mark.It sets element attribute labeling to mark each section of element, you can by contour according to every
200 meters are once marked, as shown in Figure 1.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
Claims (4)
1. a kind of contour is segmented mask method, which is characterized in that if contour is divided into according to the size of the grid in grid face
Dry section, every section carries out attribute labeling respectively.
2. a kind of contour according to claim 1 is segmented mask method, which is characterized in that the grid in the grid face is
Square.
3. a kind of contour according to claim 1 is segmented mask method, which is characterized in that realized based on ArcGIS.
4. a kind of contour according to claim 3 is segmented mask method, which is characterized in that the specific steps are：
Step 1：Contour is generated to the DEM of selection using ArcGIS；
Step 2：Use the ArcGIS formation ranges grid face figure layer consistent with the contour range；
Step 3：Using ArcGIS by the contour according to the size of the grid of grid face figure layer into Break Row；
Step 4：It sets element attribute labeling to mark each section of element, you can divided contour according to the size of grid
Section display mark.
