The <projection-transverse-mercator> element specifies the units and projection to be used for the map and reporting routines.

Frequency Parent Elements (the <projection-transverse-mercator> element is valid within): PO+ <identify-report-coordinates> PO-CHOICE <map-center-coordinate> PR-CHOICE <map-projection>

Frequency Description (in this context) PO+ Zero or more <projection-transverse-mercator> elements or other allowable projection elements may appear in the <identify-report-coordinates> element. PO-CHOICE One <projection-transverse-mercator> element or one of the other allowable projection elements may appear within the <map-center-coordinate> element. PR-CHOICE Exactly one <projection-transverse-mercator> element or one of the other allowable projection elements must appear within the <map-projection> element..

Attributes Description alias The user name of the projection. Optional. central-meridian The central meridian. Required. ellipsoid The name of the ellipsoid, either GRS80 or CLARK1866. Optional. Defaults apply. Other ellipsoids can be set using the major-axis and minor-axis. 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. Required. 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. Required. major-axis The major ellipsoid axis. Optional, can specify ellipsoid instead. minor-axis The minor ellipsoid axis. Optional, can specify ellipsoid instead. reference-latitude The reference latitude. Required. scale-factor The projection's scale factor. Required. units The map units of the projection. Valid values are "meters" and "feet". Note that if feet are used, the false easting and northing values should also be in feet. Required.
