Some Srid not supported.

[yangyong]

I tested out that 2 problems exists: 1) The Srid 28992 is sopposed to be supported in the latest PROJ.4  http://www.spatialreference.org/ref/epsg/28992/ But when it will throw exception when I use it through proj4. Similar problem will happen to all the following "sterea" projects:

2) The Srid 7415/7402 are not supported in latest proj4. I want to make sure it will supported or not.

Any hints will be appreciated.

I tried:

warmerda@gdal64[113]% ../src/cs2cs +proj=latlong +datum=WGS84 +to +init=epsg:28992
5 10
106221.92       -4432619.53 0.00

and things seem to work ok. This was with trunk, not 4.6.1. Could you be more specific about how you trigger the exception?

Test App in VS2008

warmerda,

Thanks for your attention. I think you are talking different projection with mine.

My taking projection is 28992, the string is " +proj=sterea +lat_0=52.15616055555555 +lon_0=5.38763888888889 +k=0.9999079 +x_0=155000 +y_0=463000 +ellps=bessel +units=m +no_defs":

and your talking projection is 28992, but the projection string is "+proj=latlong +datum=WGS84 " which is not correct.

I also build the DLL in the attachment with the latest brunch code, it still cannot work.

Thanks.

Yang,

Sorry for neglecting this so long.

I did test with epsg:28992 in my example. You may have to scroll to the right to see the whole cs2cs command. In order to ensure the init file lookup isn't causing any problems I just tried:

cs2cs +proj=latlong +datum=WGS84 \
  +to +proj=sterea +lat_0=52.15616055555555 +lon_0=5.38763888888889 +k=0.9999079 \
                   +x_0=155000 +y_0=463000 +ellps=bessel +units=m +no_defs
5 10 
106221.92       -4432619.53 0.00

I'm not sure why you are getting an exception, but I'd suggest first trying it at the commandline as I suspect the issue something about how you are calling PROJ.4.

Please reopen if you can reproduce this problem via the commandline tools.
