| Maptitude GISDK Help |
You can identify and modify the projection that is used on each map in a GISDK application, and convert between longitude-latitude and a map window X-Y coordinate or a local map X-Y coordinate, using these GISDK functions:
| GISDK Function | Summary |
|---|---|
| GetMapCorners() | Gets coordinates at the four corners of a map |
| GetMapProjection() | Returns the projection and coordinate system used in a map |
| GetProjectionScope() | Returns a valid scope for a particular projection |
| MapCoordToPixelXY() | Translates a longitude-latitude coordinate to a map pixel X-Y coordinate |
| MapCoordToXY() | Translates a longitude-latitude coordinate to a local X-Y coordinate, according to map projection |
| MapPixelXYToCoord() | Translates a map pixel X-Y coordinate to longitude and latitude |
| MapXYToCoord() | Translates a local map X-Y coordinate to a longitude-latitude coordinate |
| SetMapProjection() | Sets the projection and coordinate system used in a map |
For more details on projections and coordinate systems, see Using Projections and Coordinate Systems.
