This dataset is a single image tile from a collection of GeoTIFF format natural color image tiles that cover regions of Alabama, Louisiana, and Mississippi that were affected by Hurricane Katrina in August 2005. The raw imagery used to generate the final image tiles was collected simultaneously with airborne GPS and IMU data, which was used to georeference the raw imagery. The raw imagery was rectified to a plane of constant elevation. and mosaicked to generate the final image tiles. Each image tile provides data for a nominal 1.875 minute (in latitude and longitude) cell area. The source imagery was obtained in September 2005 and used to produce georeferenced, planar rectified imagery with a one foot ground resolution. Imagery was acquired at one foot ground sample distance (GSD) resolution. Flight height maintained during mission was 10,000 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was obtained and processed by all digital means beginning with data acquisition using an ADS40 digital airborne sensor. The orthophotos are available in GeoTIFF form in Geographic Coordinates (decimal degrees), NAD83.
The general purpose of the imagery collection and processing is to provide data for federal and state agencies to visually denote and quantify damage areas from no damage areas, and to quantify the degree of damage as heavy, moderate or light.

The images are clipped to the neatline of the USGS sixteenth quadrangle boundaries. The file naming pattern is 'K_MRC#_sixteenth#'. The K identifies the imagery as relating to Katrina, the MRC number is taken from the national quadrangle index, and the sixteenth number identifies which sixteenth quadrangle the image covers. The sixteenth numbers begin with '1' in the north west corner of the quadrangle and increase to '4', then they move back to the west and down one row to '5' and increase to '8', etc., until '16' is reached in the southeast corner of the quadrangle.

These data are compiled to provide the most accurate product achievable within the scope of the project.; Quantitative Value: 12 meters, Test that produced the value: Relative horizontal accuracy was tested by measuring points in the overlap areas between image strips. Based on the expected accuracy of GPS/IMU solution used to georeference the imagery, this relative accuracy should be representative of the absolute accuracy of the image strips.
These data cover portions of Alabama, Louisiana, and Mississippi affected by Hurricane Katrina in August 2005.
Sample points taken from overlapping areas of adjacent image strips that contributed image chips to each orthophoto tile are typically consistent to the 10-12 pixel level.

The imagery was collected at an altitude of 10,000ft using an ADS40 digital sensor. Image quality was verified during the post flight
review phase to minimize cloud cover. Airborne GPS and IMU data were collected simultaneously with the imagery and merged during post processing to provide a combined position and orientation solution (POS). The POS data was used to georeference the raw image strips. The georeferenced image strips were planar-rectified to a constant elevation representative of the average elevation of a block. The red, green, and blue bands were combined to produce the resulting natural color orthos. The image strips were combined in a mosaic, and project specific tiles were clipped from the mosaic. No feathering was applied during mosaicking, causing seams between adjacent images to be visible in some tiles.
