- Non Standard AUTO Namespace
- ===========================
- The WMS standard supports a small number of "automatic" coordinate reference systems that include a user-selected centre of projection. These are specified using::
- AUTO:auto_crs_id,factor,lon0,lat0
- for example::
- CRS=AUTO:42003,1,-100,45
- .. note:: in GeoServer 2.8.x AUTO and AUTO2 namespaces are treated identically.
- .. note:: in GeoServer 2.8.x the factor parameter in the AUTO namespace is ignored. The BBOX parameter to GetMap must therefore be specified in metres.
-
- The WMS standard provide projections with IDs in the range 42001 to 42005.
- .. list-table::
- :widths: 20 80
-
- * - ID
- - Projection
- * - 42001
- - Universal Transverse Mercator
- * - 42002
- - Transverse Mercator
- * - 42003
- - Orthographic
- * - 42004
- - Equirectangular
- * - 42005
- - Mollweide (not supported in GeoServer 2.8.x)
- GeoServer also supports some non-standard coordinate reference systems.
- These are
- .. list-table::
- :widths: 20 80
-
- * - ID
- - Projection
- * - 97001
- - Gnomonic
- * - 97002
- - Stereographic
- .. note:: the auto stereographic projection uses a sphere. It does this by setting the semi minor axis to the same value as the semi major axis.
