Abstract This dataset contains imagery for the Carson National Forest. The imagery was flown to provide coverage after the 2011 Pacheco Fire.

Purpose To provide post fire imagery for planning and restoration purposes.

Supplemental Information Imagery was collected in late summer and early fall of 2011 in support of US Forest Service management efforts after the summer fires of 2011. Stereo imagery was collected with a large-format, digital camera as four simultaneous bands with an 8-bit depth per band and at a GSD of less than 0.30 meters. The resulting 4-band images were rectified to a USGS DEM. An Aerial-Triangulation was performed on the imagery using image tie points with the ABGPS and IMU. Supplemental breaklines were merged with the USGS DEM and subsequently used to rectify DOQQ image mosaics for final RGB and NIR orthophotography.

Access Constraints There are no limitations for access.

Use Constraints These orthophotos were designed for optimal viewing at 1:2400 scale. Performing quality control or plotting images at scales larger than 1:1200 is not recommended. Field verification of data accuracy should occur prior to design level tasks that are dependent on the data.

Process Step

Process Description Aerial photography was flown using a digital mapping camera. Vexcel UltraCam X, focal length of 100.500 mm, Pixel size of 7.2 microns. Imagery collected at ground sample distance (GSD) such that no area has a resolution greater than 0.35m. Imagery is 4-band (RGBN), 8 bits per band.

Process Step

Process Description Orthophotos were rectified using a USGS 10-30m DEM. The ABGPS and IMU was used in conjunction with image tie ipoints to perform a more solid Aerial Triangulation of all imagery. Accuracy verification occcur prior to design level tasks that are dependent on these data.
