Description:
Abstract:
This data set is a satellite image of the lands and waters of the State of Louisiana. It was created by combining fourteen scenes of 30-meter resolution Landsat Thematic Mapper (TM) imagery with 15-meter resolution panchromatic imagery. The TM and panchromatic imagery for each scene are coincident. The original image data were geo-rectified and resampled using cubic convolution to 25-meter (TM) and 12.5-meter (pan) cells by the Earth Resources Observation Systems (EROS) Data Center. These data were purchased from EROS by the Louisiana Department of Environmental Quality (northern half of state) and the USGS's National Wetlands Research Center Lafayette (southern half of state.) The processing to produce a seamless enhanced image was performed at LDEQ by a LDEQ contractor. The work was funded by a grant from the US EPA to the LDEQ Non-Point Source Water Pollution Section. The image was constructed from a red, green, blue (RGB) composite of bands 7,5 & 3 fused with the panchromatic image to produce the enhanced TM pan sharpened mosaic.
Purpose:
The merged satellite image was produced to support on-going research for the LDEQ Non-point Source Program by providing a more current view of land cover/land use within Louisiana and to support NWRC's work in evaluating Louisiana's coastal wetlands.

Each multispectral scene was subset to bands 3, 5, 7 and arranged in RGB-753 order. Each multispectral and panchromatic scene was converted to reflectance using header information. The reflectance scenes were matched and mosaiced in path order. Mosaics attempted to exclude bad data areas and clouds when possible. Multispectral and panchromatic imagery were separately mosaiced.
