Hello All,

Any ADE_* function which can be useful?

The following is directly from acmaplisp.chm:

 

 

Gets information about a projection system.

 

(ade_projgetinfo cscode info_type)

 

Returns a piece of projection system information or nil.

 

cscode Coordinate system code (string), eight characters

info_type Information type (string); see Information Types below

 

Information Types description Description (string). For example, "World Geodetic System of 1984 Latitude/Longitude in Degrees".

 

projection Projection (string). For example, "Unity Conversion, produce/accept lat/longs".

 

datum Datum (string). For example, "North American Datum of 1927, Mean Values".
