3. Problem A majority of the maps available for water planning in the Paso del Norte region, whether produced by the US or Mexico, have the typical “blank” region on the other side of the border. A majority of the maps available for water planning in the Paso del Norte region, whether produced by the US or Mexico, have the typical “blank” region on the other side of the border. This is also true to a lesser extent for maps of Texas and New Mexico. This is also true to a lesser extent for maps of Texas and New Mexico. In most cases the information is available, but the basic layers are at different spatial scale, resolution, and extent.

Where digital data are not available, tasks were designed to assess requirements for their development. In addition, the GIS system should contain other databases that would be useful for regional water planning.

12. Framework Data Detail The geodetic component consists of a database of geographic points, with surveyed location and elevation. The geodetic component consists of a database of geographic points, with surveyed location and elevation. The orthoimagery component consists primarily of aerial photography that can be used as a source of information or as a backdrop to other databases. The orthoimagery component consists primarily of aerial photography that can be used as a source of information or as a backdrop to other databases. The elevation component consists of two data types. The first data type consists of regular interval contours that represent elevation of the land surface and the second data type is called a digital elevation model (DEM).
