State-wide spatial data presentation requiring true area measurements.
Replaces NAD83(HARN) / TX Albers (CRS code 3085). Replaced by NAD83(2011) / TX Albers (CRS code 6579). For state-wide spatial data presentation requiring shape preservation use NAD83(NSRS2007) / TX LC (CRS code 3666).
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
