<ALBERS-EQUAL-AREA-CONIC-SRS>

IMF Developer's Guide » Map Configuration » <ALBERS-EQUAL-AREA-CONIC-SRS>

The <ALBERS-EQUAL-AREA-CONIC-SRS> element defines a spatial reference system based on the Albers Equal Area Conic projection. This element is required if your map or services use EPSG codes based on this projection. For more information about the EPSG codes used in OpenGIS services, see http://www.epsg.org.

Frequency	Parent Elements (this element is valid within):
PO+	<SRS-LIST>

Attributes	Description
srs	The SRS code. For example, use "EPSG:42102" for BC Albers. Required.
title	The name of the projection to be displayed to the user. Required.
central-meridian	The central meridian. Required.
ellipsoid	The name of the ellipsoid. See valid values on the bottom of this page. Required.
false-easting	The X adjustment. Specify in meters unless the projection units are feet, in which case the false easting and northing values should also be in feet. Optional.
false-northing	The Y adjustment. Specify in meters unless the projection units are feet, in which case the false easting and northing values should also be in feet. Optional.
latitude-of-origin	The reference latitude. Required.
standard-parallel-1	The first standard parallel. Required.
standard-parallel-2	The second standard parallel. Required.
units	The map units of the projection, usually meters. Can also be set to feet. Note that if feet are used, the false easting and northing values should also be in feet. Required.

Frequency	Description (in this context)
PO+	The <ALBERS-EQUAL-AREA-CONIC-SRS> element is optional but may appear one or times within the <SRS-LIST> element.
