Interface ICoordinateSystemCatalog

Defines a coordinate system catalog

Namespace: OSGeo.MapGuide.MaestroAPI.CoordinateSystem
Assembly: OSGeo.MapGuide.MaestroAPI.dll
Syntax
public interface ICoordinateSystemCatalog
Examples

This example uses the ICoordinateSystemCatalog to create a simple coordinate system transformation to transform points.

IServerConnection conn;
...
ICoordinateSystemCatalog csCatalog = conn.CoordinateSystemCatalog;
//Find the source and target coordinate system definitions
CoordinateSystemDefinitionBase srcCs = csCatalog.FindCoordSys("LL84");
CoordinateSystemDefinitionBase dstCs = csCatalog.FindCoordSys("WGS84.PseudoMercator");
//Create the transform using the WKTs of the source and target coordinate system definitions
ISimpleTransform trans = csCatalog.CreateTransform(srcCs.WKT, dstCs.WKT);

double x = -71.061342;
double y = 42.355892;
double tx;
double ty;

trans.Transform(x, y, out tx, out ty);
//tx and ty will contain the transformed coordinates
