Hello, Adam.

I'm sorry you cannot add new SRS without compiling the source code. If you have 
basic Java knowledge I can tell you which little changes need to be done.

However, I don't think you need to do that in this particular case. After 
reading this:

http://en.wikipedia.org/wiki/North_American_Datum

and doing some tests with a shapefile of some lake in MN, my conclusion is that 
the difference between EPSG:26915 and EPSG:32615 is so small that most GIS 
applications don't perform any change between them.

You can do a test with gvSIG (desktop) to see if it makes a difference to 
reproject from EPSG:26915 to EPSG:32615. Using the gdal tools ( 
http://fwtools.maptools.org/ ) the command would be:

ogr2ogr -s_srs epsg:32615 -t_srs epsg:26915 lake_mn_26915.shp lake_mn_32615.shp

I have done that and the resulting shapefile is exactly the same as the source 
shapefile.

In short: you can set the view to EPSG:32615 in gvSIG Mobile and add your 
shapefiles/ECW/WMS in EPSG:26915, and everything should be ok.

Asunto: [Gvsig_english] The EPSG code I want to use is not in the SRS list


Greetings,

I am using GvSig Mobile 0.3

When I go into application setup menu to set the spatial reference system 
(SRS).  I notice that the EPSG codes are I want to use are NOT included in the 
list.

I want to use EPSG Code 26849 or 26915.

How do you add EPSG codes to the list??????

Adam
