The State of Texas has begun to realize the importance that remote sensing has on understanding the rapidly changing state of the environment. Texas is unique in its varying environments, ranging from wetlands to desert, agriculture to forestry. Currently, TRCP has identified three critical areas as pilot programs for developing a regional change program within the state.

1.South Texas Coastal Program - In conjunction with the TNRCC study, hydrological modeling along the San Antonio and Nueces River (SANDAP) watersheds will be studied.

Ongoing work in the SANDAP area includes the TNRCC hydrologic models of the watersheds, Marine Science Institute (MSI) vegetation and water sampling at the coastal wetlands, UT/BEG GPS and geoid modeling of the region, as well as numerous pending proposals for Land use/ Land Cover studies.

In addition the current research, the TRCP acquired in Summer 1996, Calibrated Airborne Multispectral Scanner (CAMS) and AIRSAR data over the SANDAP region which will be made available for collaborative research. For more information about the recent data acquisition, click here.

The Center for Space Research has begun an initial analysis of the CAMS and AIRSAR imagery over the SANDAP region. The preliminary image analysis is being conducted over two sites:

Rincon Bayou: Investigation using high resolution imagery (CAMS and AIRSAR) for wetland mapping

Mission Creek: Investigation using high resolution Topographic SAR (TOPSAR) for topographic mapping.


2. Rio Grande - With the passage of NAFTA, the environmental change along the Rio Grande River is of great concern for the State, including pollution, water resources, and economic/socio development.

Ongoing work in the Lower Rio Grande Valley includes a collaborative research program between UT-Pan American, UTCSR, and UT-San Antonio to map riparian vegetation. UT-Pan Am is also creating a GIS database of soils and geology for the Rio Grande River delta.

3. Agriculture/Rangeland - Agriculture comprises 20% of the state's economy and is a critical component for understanding land use within the state. Agriculture has perhaps the largest base and coverage of the State. USDA/Weslaco, Texas A&M, and Texas Tech Universities have led the way in agriculture science. Texas Tech and TAMU are currently leading the studies of plant stress and agriculture management practices.
