 "description": "<DIV STYLE=\"text-align:Left;\"><P STYLE=\"margin:0 0 14 0;\"><SPAN><SPAN>In 2001, the Texas Water Development Board (TWDB) Groundwater Availability Models Team developed a custom GAM coordinate statewide mapping system to best serve the parameters for their desired data outputs. The GAM projection parameters are a modified version of the Texas Centric Projection/Albers (TCP/A) parameters, later renamed as the Texas State Mapping System/Albers Equal Area (TSMS/AEA). For GAM, the coordinate units are in US Survey Feet instead of meters and the Latitude of Projection is at 31.25 North instead of 18.0 North. Albers projection was chosen since it best minimalizes area distortion at mid-latitudes. U.S. Survey Foot was chosen as the linear unit since most source data in the State of Texas are also in feet. This file was created and edited in the GAM coordinate statewide mapping system and is used in the official TWDB GAM models.<\/SPAN><\/SPAN><\/P><\/DIV>",
