NOW AVAILABLE: 2018 AERIAL PHOTOGRAPHY
Background: The Flood Commission began acquiring digital aerial photography and LiDAR products for Doña Ana County in 2004. This initial project was updated in 2007 with aerial photography only. Another project was completed in 2010 with new aerial photography and new LiDAR data. Each project increased the coverage area. The 2014 edition updated the aerial photography. LiDAR was flown over areas where substantial changes have occurred, such as the I-10/I-25 interchange and the new rail yard in Santa Teresa. The 2018 project covered 2331 square miles of the County.
Potential Uses: This data can be extremely useful for preliminary engineering drawings, flood mapping, site planning, modeling, engineering studies, and presentations.
Costs: The data is available for $50 per section (PLSS), per layer. The entire dataset is available for $10,000.
