Dear Sirs / Madams,

 

I'm a new user to gvSIG 1.1.

 

Actually, I don't know how to setup my user define projection parameters.
However, when I open the file "db_esri.script" in the CRS extensions
directory, I found that it looks like the ERSI .prj file. Therefore, I put a
row in the file as below:

 

INSERT INTO ESRI
VALUES(1000,'PROJCS["HK208507_VSNL",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984"
,SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT[
"Degree",0.0174532925199433]],PROJECTION["Mercator"],PARAMETER["False_Eastin
g",2000000.0],PARAMETER["False_Northing",2000000.0],PARAMETER["Central_Merid
ian",112.0],PARAMETER["Standard_Parallel_1",10.0],UNIT["Meter",1.0]]','HK208
507_VSNL','GCS_WGS_1984','D_WGS_1984')

 

It's basically a Mercator projection in WGS84 at 112E 10N, FE and FN
2,000,000m

 

But when I choose this projection, fatal error was resulted and exit the
program.

 

The same error is encountered if I choose ERSI projection code 3000. It is a
Mercator projection as well.

 

Please help.

 

Thank you very much for your kind attention.

 

Best Regards,

 

Kwong
