[gdal-dev] Validating a projection

[Doug McCorkle]

Hello,

I am trying to add this projection to our runtime environment:

PROJCS["USA_Contiguous_Albers_Equal_Area_Conic_USGS_version",
    GEOGCS["GCS_North_American_1983",
        DATUM["D_North_American_1983",
            SPHEROID["GRS_1980",6378137.0,298.257222101]],
        PRIMEM["Greenwich",0.0],
        UNIT["Degree",0.0174532925199433],
        AUTHORITY["EPSG","4269"]],
    PROJECTION["Albers_Conic_Equal_Area"],
    PARAMETER["False_Easting",0.0],
    PARAMETER["False_Northing",0.0],
    PARAMETER["Central_Meridian",-96.0],
    PARAMETER["Standard_Parallel_1",29.5],
    PARAMETER["Standard_Parallel_2",45.5],
    PARAMETER["Latitude_Of_Origin",23.0],
    UNIT["Meter",1.0],
    AUTHORITY["EPSG","102039”]]

in the esri_extra.wkt file with:

102039,PROJCS["USA_Contiguous_Albers_Equal_Area_Conic_USGS_version",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Albers_Conic_Equal_Area"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",-96.0],PARAMETER["Standard_Parallel_1",29.5],PARAMETER["Standard_Parallel_2",45.5],PARAMETER["Latitude_Of_Origin",23.0],UNIT["Meter",1.0],AUTHORITY["EPSG","102039”]]

When I try to validate the projection I get this in the debug output:

OGRSpatialReference::Validate: PARAMETER Central_Meridian for PROJECTION Albers_Conic_Equal_Area is an alias for longitude_of_center.

I am unsure of what to do with this debug information to correct the definition. This is the proj4 definition:

# USA Contiguous Albers Equal Area Conic USGS version
<102039> +proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=23.0 +lon_0=-96 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs <>

Any pointers on how to correct the issue is appreciated. Thanks in advance.

Doug
