[postgis-users] AddToPROJ4SRSCache: couldn't parse proj4 string - major axis or radius = 0 or not given

[David Wu]

Hi there,

 

I need to add a projection to support an imported shapefiles dataset with
the following projection:

PROJCS [              "Business Analyst Projection",

                                GEOGCS[             

                                                "GCS_WGS_1984",

                                                DATUM[
"D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],

                                                PRIMEM["Greenwich",0.0],

 
UNIT["Degree",0.0174532925199433]],  

                                PROJECTION["Equidistant_Conic"],

                                PARAMETER["False_Easting",0.0],

                                PARAMETER["False_Northing",0.0],

 
PARAMETER["Central_Meridian",-88.02657853618898],

 
PARAMETER["Standard_Parallel_1",41.82305904132364],

 
PARAMETER["Standard_Parallel_2",41.82305804132364],

                                PARAMETER["Latitude_Of_Origin",0.0],

                                UNIT["Meter",1.0]          ]

 

I used the following SQL to add the projection to the spatial_ref_sys
table:

 

INSERT INTO spatial_ref_sys (srid, auth_name, auth_srid, srtext,
proj4text) VALUES (9998, 'EPSG', 9998, 

                'PROJCS["Business Analyst Projection",

                                GEOGCS["GCS_WGS_1984",

 
DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],

                                                PRIMEM["Greenwich",0.0],

 
UNIT["Degree",0.0174532925199433]],

                                PROJECTION["Equidistant_Conic"],

                                PARAMETER["False_Easting",0.0],

                                PARAMETER["False_Northing",0.0],

 
PARAMETER["Central_Meridian",-88.02657853618898],

 
PARAMETER["Standard_Parallel_1",41.82305904132364],

 
PARAMETER["Standard_Parallel_2",41.82305804132364],

                                PARAMETER["Latitude_Of_Origin",0.0],

                                UNIT["Meter",1.0]]', 

 

                '+proj=eqdc +lat_0=41.82305904132364 

                                +lon_0=-88.02657853618898

                                +lon_1=-88.02657853618898 

                                +lon_2=-88.02657853618898 

                                +x_0=0

                                +a=6378137.0

                                +ellps=WGS84 

                                +datum=WGS84 

                                +units=m 

                                +no_defs');

 

When I tried to do a transform test [ update major set
geom=transform(geom, 4326) ], I go the following error:

ERROR:  AddToPROJ4SRSCache: couldn't parse proj4 string: '+proj=eqdc


                                +lat_0=41.82305904132364

                                +units=m 

                                +no_defs': major axis or radius = 0 or not
given

 

BTW, I found no documentation that provides a complete listing of
parameters I need to set for eqdc projection.



Thanks for any hint.
