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
+y_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
+lon_0=-88.02657853618898
+lon_1=-88.02657853618898
+lon_2=-88.02657853618898
+x_0=0
+y_0=0
+a=6378137.0
+ellps=WGS84
+datum=WGS84
+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.
