gis:load-coordinate-system

gis:load-coordinate-system file

Loads a new global projection used for projecting or re- projecting GIS data as it is loaded from a file. The file must contain a valid Well-Known Text (WKT) projection description.

WKT projection files are frequently distributed alongside GIS data files, and usually have a “.prj” filename extension.

Relative paths are resolved relative to the location of the current model, or the user’s home directory if the current model hasn’t been saved yet.

The GIS extension does not support all WKT coordinate systems and projections. Only geographic ("GEOGCS") and projected ("PROJCS") coordinate systems are supported. For projected coordinate systems, only the following projections are supported:

• Albers_Conic_Equal_Area
• Lambert_Conformal_Conic_2SP
• Polyconic
• Lambert_Azimuthal_Equal_Area
• Mercator_1SP
• Robinson
• Azimuthal_Equidistant
• Miller
• Stereographic
• Cylindrical_Equal_Area
• Oblique_Mercator
• Transverse_Mercator
• Equidistant_Conic
• hotine_oblique_mercator
• Gnomonic
• Orthographic

See remotesensing.org for a complete list of WKT projections and their parameters.
