Data Types of KSC
Data were incorporated into a single database for processing and analysis. After the database was compiled, a direct comparison of the multi-year/multi-sensor datasets was possible after the application of geometric and radiometric corrections.
Database Description
The database over KSC consists of remotely sensed data collected from several spaceborne and airborne sensors, GIS layers compiled by researchers at Dynamac Corporation under contract to NASA's Biomedical Office at KSC, and GPS data collected by CSR personnel at various sites over KSC.
1. Remotely Sensing Data
The remotely sensed datasets over KSC supplied by Dynamac were acquired between 1987 and 1998 using a wide range of sensors. These datasets include:
1987 Landsat Thematic Mapper (TM),
1989 Landsat-TM,
1991 SPOT Multispectral (XS) and Panchromatic,
1993 Calibrated Airborne Multispectral Sensor (CAMS),
1994 SIR-C Synthetic
Aperture Radar,
1996 AVIRIS,
1997 Landsat-TM
The Landsat-TM scenes were acquired during the month of April, which is ideal for studying wetland vegetation because new grasses and vegetation have emerged. The SPOT scenes were acquired in November, and the SIR-C image was collected during the October 1994 Shuttle Mission. The CAMS data were acquired during July 1993 as several strips covering the area. The AVIRIS data were acquired March 1996 over a significant portion of Merritt Island.
2. GIS Layers
Ancillary data were provided by Dynamac based upon their previous analysis of the area. The thematic images of vegetation and soil content were created based upon the 1987 |
1989 Landsat TM scene (Bands 4,3,2)

Landsat-TM scene combined with aerial photography, intensive ground truth and extensive knowledge of the terrestrial vegetation. These GIS files include soils, vegetation types, impoundment areas, and KSC jurisdictional lands.
