Convert Proj File

Geocadastre uses a Map Projection file to provide a table of Map Projection parameters.
The default one for Australia is called "MapProjections_Aust.csv".

A typical record in that file is as below:

61,AGD_1984,6378160,298.25,Mercator,Zone_48,0,105.000000000000,500000,10000000,0.99960,Metres,1,0,0,Zone_48,Zone_48,,South,

Other software systems (Arc Map, Mapinfo etc) use a different file format and a separate file for each projection.
A typical ESRI projection file is as below:

esriSpatialReference>PROJCS["GDA_1994_MGA_Zone_54",GEOGCS["GCS_GDA_1994",DATUM["D_GDA_1994",SPHEROID["GRS_1980",6378137.0,298.257222101]],
PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",500000.0],
PARAMETER["False_Northing",10000000.0],PARAMETER["Central_Meridian",141.0],PARAMETER["Scale_Factor",0.9996],
PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]

Browse to the directory which has the ESRI files in it, then select the ACS projection file to update.

The routine will read every ESRI projection file in the specified directory and add the
information to the selected ACS projection file.
