Abstract:

This data set consists of natural color imagery for the SE Texas and SW Louisiana area affected by Hurricane Rita on September 24, 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.

Purpose:

To provide imagery for the damaged areas of Louisiana, and Texas.

Supplemental_Information:

This metadata record was generated using the original metadata records from the imagery. This metadata record documents the data as a whole. For details on each individual frame, please consult the metadata for that particular frame.
