2005 Central Gulf Coast (Post Hurricane Katrina) natural color Imagery

Description:
Abstract:
This data set consists of natural color imagery for the Central Gulf Coast area affected by Hurricane Katrina on August 29, 2005. From the original metadata - The raw imagery was collected simultaneously with airborne GPS and IMU data, which was used to georeference the imagery by providing a combined position and orientation solution (POS). The imagery was rectified to a plane of constant elevation, and mosaiced 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 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 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.
Purpose:
To provide imagery for the damaged areas of Louisiana, Mississippi, and Alabama.
