State-wide spatial data presentation requiring shape preservation.
For applications with an accuracy of better than 1m, replaced by NAD83(HARN) / TX LC (CRS code 3084). For state-wide spatial data presentation requiring true area measurements use NAD83 / TX Albers (CRS code 3083).
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
