Imagery data for the Vegetation Mapping Inventory Project of Amistad National Recreation Area

Metadata Updated: June 5, 2024

This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here.

During the planning and coordination phase, CTI staff reviewed all available existing digital imagery for its potential use as the base-map for the vegetation mapping at AMIS. The most promising and easy to access was the data catalog found on the Texas Natural Resource Information System (TNRIS) website. Navigating to the orthoimagery-statewide web page, the list of existing imagery covering AMIS included multiple products produced annually by the U.S. Department of Agriculture’s National Aerial Imagery Program (NAIP). The corresponding NAIP 2010 1-meter (pixel resolution) quarter-quad datasets for AMIS were downloaded and used during the preliminary planning and mapping stages. Since 2012, other orthoimagery covering AMIS was made available on TNRIS and was downloaded by CTI. These included the 2012 and 2016 versions of the NAIP 1-meter quarter quads and the 2015 Texas Orthoimagery Program (TOP) 50-cm quarter quads (Figure 13). All contained an infrared band and the NAIP 2016 product was determined useful for supplying the most up-to-date vegetation patterns (especially in the dynamic inundation zone and other recently disturbed sites) and as an ancillary dataset if needed for hard to view canyons and within shadows along the river bluffs. Overall the 2015 TOP product was found to be superior to the 2016 NAIP imagery due to its finer resolution and higher contrast. The 2015 TOP imagery was then selected and used as the primary basemap for the remainder of the mapping efforts.
