• Costal Impact Assistance Program• What does it do? • The CIAP program provides funds to Outer Continental Shelf oil and gas producing States for the conservation, protection and preservation of coastal areas, including wetlands. (BOEMRE, 2011) • States include Alabama, Alaska, California, Louisiana, Mississippi, and TEXAS!
• The Texas Water Development Board (TWDB) will digitize the coastal historical photography of the Texas coast for selected decades between 1940 and 1990 • This project will serve as a historic and educational record of visualizing coastal change and erosion through time!
• In an average month at TNRIS the 4 interns could… • Generate approximately 5200 scans of archived historical aerial photos at 800dpi OR approximately 2600 scans at 1000dpi. • Or produce approximately 625 georeferenced frames.• Each aerial scanned ensures permanent preservation of the historic photo and prevents it from becoming damaged or misplaced.• The georeferencing of these frames is one step in providing the public free, downloadable access to the historic archives of TNRIS.
