[mapserver-users] cutom EPSG db for Canada problem

[Chuanyun Fei]

Hi All,

We current add some epsg codes (got from DM Solutions) for Canada and
North American into the epsg db located in c:\proj\epsg and
C:\proj\nad\epsg, for example:

# WGS84 / Ortho NorthAm
<42201> +proj=ortho +lat_0=45.0 +long_0=-100.0 +x_0=0.0 +y_0=0.0
+ellps=WGS84 +datum=WGS84 +units=m no_defs <>

Our MapScript and MapServer are 3.6 runing on Win2000. We wondering why
some points work, some don't. For example:

convert EPSG:4326 => EPSG:42201:
input (-128, 32)  => (4262324.1145246,4744679.5950324)
input (-128, 31)  => nothing

Is there some restraints for the input points (bounding box)?

Thanks a lot in advance.
