Create a contour map
1. Load a data set:
| |
1.1 Choose the File | Open
command to load:
| |
- scattered XYZ points;
- GPS NMEA files;
- ASCII USGS Digital Elevation Model files (.dem
extension);
- Surfer 6 and Surfer 7 files (.grd extension);
- BMP, JPG, PNG, GIF images;
- 3DField documents (.3df extension). |
| or |
|
|
| |
1.2 Choose the File | Open 2D/3D
data
command to load a matrix data |
|
| |
2. You can change the gridding method to interpolate the scattered data over
the grid:
| |
- system of linear equations (the default); |
| |
- kriging; |
| |
- inverse distances;
- triangulation;
- minimum curvature |
|
| |
3. Double click on specified map in Map manager window (or choose
Objects | Maps list command):
| |
- contour map;
- color fill contour map;
- shaded relief;
- color relief;
- color cells;
- color points;
- direchlet tesselations;
- delauney triangles |
4. You can change a properties of:
| |
- grid;
- series of points;
- boundary outlines;
- color scale;
- title of map;
- legend;
- base map;
- axes;
- language;
- harder copy of map (size and format of graphic file) |
|

5. Click the OpenGL view button (or choose the View
|
OpenGL view command) to draw the 3D map. |
