Abstract This data set consists of photo centers of raw aerial images representing multi-spectral (red, green, blue, near-infrared) digital aerial imagery of the Las Conchas Fire that burned in the Santa Fe National Forest in the Jemez Mountains of central New Mexico in the summer of 2011. The Area of Interest (AOI) is 632,000 acres and is larger than the actual burn acreage of approximately 150,000 acres that lies within the AOI. Aerial imagery was collected with a frame - based Z/I Digital Mapping Camera at an average elevation of 4,500 feet above ground; generating an average ground sample distance (gsd) of 0.45 feet. The aerial imagery will be used to create natural color and false color infrared digital orthophotos of the AOI at a re-sampled gsd of 0.5 foot. The imagery will support the Forest Service Burned Area Emergency Response (BAER) program that addresses landscape damage due to the fire, with the goal of protecting life, property, water quality, and deteriorated ecosystems from further damage now that the fire is out. Airborne GPS procedures were used to determine the camera station coordinates of each exposure. The nearest CORS base station was used to post process these coordinates with Applanix software into the project datum of NAD83/NAVD 88, UTM Zone 13, meters.

Purpose This shapefile was created to determine center points for imagery that was acquired post fire to support the Forest Service Burned Area Emergency Response (BAER) program.

Process Step

Process Description Airborne GPS data and USGS photoidentifiable ground control were used to control a softcopy aerotriangulation block solution. External orientation parameters derived from the aerotriangulation solution were used to provide the horizontal control for each photograph. Vertical control for the orthorectification process was obtained from digital elevation model obtained from the NED.

Process Step

Process Description Mosaicked digital orthorectified quarter-quarter quadrangles (DOQQQs) for the project area defined in the Southwestern Jemez Restoration project area Shape files were produced. The DOQQQs cover the entire image area of one quarter of a USGS standard quarter quadrant, with a 100 meter buffer on all four sides. Image Quality: Wilson and Company shall radiometrically balance the files used to create the DOQQQs to eliminate any checker board pattern appearance. However, it is the USFS's preference not to have the DOQQQs "radiometrically balanced" with other neighboring DOQQQs. The DOQQQs shall not contain any borders, artifacts, or other non-image items. Feathering and/or smoothing should be applied to seamlines within or between images so there is not a noticeable edge or displacement effect. Coverage: When a DOQQQ partially covers the fire project area boundary; Wilson and Company may elect to submit a partial DOQQQ so that it completely covers the fire project area boundary. Any partial DOQQQ shall include a 100 meter buffer on the outside of the fire project area boundary. Offset: The offset between adjacent DOQQQ tiles, defined as the distance between identifiable features on two neighboring images, shall not exceed two times the horizontal accuracy requirement. File Format. The DOQQQ tiles shall be a 3-band, RGB, 8-bit per band georeferenced tagged image file format (GeoTIFF).
