MzMapProjection Class |
Note: This API is now obsolete.
The ProjectionString is a WKT string for a spatial reference system. A number of abbreviated strings also exists, i.e., "UTM-33" for a WGS-84 UTM zone 33 projection, and "LONG/LAT" for WGS-84 geographical coordinates.

The MzMapProjection type exposes the following members.
Name | Description | |
---|---|---|
MzMapProjection |
Create and initialize a mapprojection with the specifed projection string.
|
Name | Description | |
---|---|---|
Name |
The short name of a projection.
The short name is not unique amongst all WKT projections If the ProjectionString is not a WKT projection string, the ProjectionString itself is returned as the short name. | |
ProjectionString |
Returns the WKT projection string, or one of the projection abbreviation strings.
|
Name | Description | |
---|---|---|
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
Geo2Proj |
Convert coordinates from geographical coordinates to projection coordinates
| |
Geo2ProjRotation |
Convert a rotation from true north
into a rotation from map projection north
It subtracts the convergence value from the true north rotation value The convertion depends on the geographical location. | |
Geo2Xyz |
Convert coordinates from geographical coordinates to 3D coordinates.
The 3D coordinate system origin is at the earth center (ellipsoid center) | |
GetConvergence |
Get the convergence (orientation towards true north) at the given geographical location.
The convergence is the angle measured clockwise from true north to the north-south gridline passing through the specified coordinate. | |
GetHashCode | Serves as the default hash function. (Inherited from Object.) | |
GetOrigin |
Get the geographical origin of the map projection
| |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IsGeographical |
Checks whether a projection string is using longitude/latitude
coordinates
| |
IsValidProjection |
Checks whether a projection string is a valid projection string
| |
IsValidUtmZone |
Checks whether a projection string is a valid UTM zone projection string
| |
Longitude2UtmZone |
Get the projection string for the UTM zone best matching the longitude coordinate
| |
Proj2Geo |
Convert coordinates from projection coordinates to geographical coordinates
| |
Proj2GeoRotation |
Convert a rotation from map projection north
into a rotation from true north.
It adds the convergence value to the projection north rotation value The convertion depends on the geographical location. | |
ProjectionOrigin |
Returns the geographical origin of the projection defined by the
projstring If the projection string is not a valid WKT string, an exception is thrown. | |
ProjectionShortName |
Get the short name out of a WKT projetion string.
The short name is not unique amongst all WKT projections If the projString is not a WKT projection string, the projString itself is returned as the short name. | |
ToString | Returns a string that represents the current object. (Inherited from Object.) | |
Xyz2Geo |
Convert coordinates from 3D coordinates to geographical coordinates.
The 3D coordinate system origin is at the earth center (ellipsoid center) |
