2. 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. 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. This has precluded their combined use.

3. Purpose The purpose of this project is to develop and create a regional geographic information system (GIS) to support regional water planning in the Paso del Norte region. The basic geographic spatial databases, also known as framework or basemap data, consists of seven components. These are: geodetic control, orthoimagery, elevation, transportation, hydrography, governmental units, and cadastral information.

6. Framework Data 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 areal photography that can be used as a source of information or as a backdrop to other databases. The orthoimagery component consists primarily of areal 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 is called a digital elevation model (DEM) and the second data type consists of regular interval contours that represent elevation of the land surface.

9. Approach Continued Where digital data are not available, tasks will be designed to assess requirements for their development. Where digital data are not available, tasks will be designed to assess requirements for their development. In addition, the GIS system should contain other databases that would be useful for regional water planning. In addition, the GIS system should contain other databases that would be useful for regional water planning. –Examples include groundwater aquifer boundaries, water well locations, watershed boundaries, and landuse classifications.

10. Approach Continued Project team members will work closely with regional planners to identify and incorporate other useful information. Project team members will work closely with regional planners to identify and incorporate other useful information. As the combined products are developed, they will be shared broadly, with each participating unit making them available via their websites. Also, the procedures developed in this project could be used as a template for other border areas.

Deliverables from the project would consist of digital GIS layers of relevant themes useful for water planning within the framework and basemap data for the seven geospatial components described above. In addition, other useful information would be incorporated into the system. The information would be provided jointly by the participating entities from Internet websites as well as CDROM.
