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) multispectral imagery. The original data were geo-rectified and resampled to 25-meter 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 multispectral 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.

Purpose:

The mosaic 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.

These unaltered data should not be redistributed without all of the elements of the metadata listed in the Supplemental_Information section of this metadata document. It is recommended that third parties wishing to use these data obtain them from the Distributor listed in this metadata document. If these data are altered or incorporated into another dataset, they are not to be redistributed without also: altering the name of the dataset, including a Content Standards for Digital Geospatial Metadata (FGDC-STD-001-1998) compliant metadata file that describes the dataset and reflects the alteration steps that makes the new dataset different from this one, and citing this metadata as a source for the altered dataset using the source citation specified below. If these digital data are used in the production of a report or in compilation of a stand-alone printed map, then this dataset is to be cited in the report or on the map using the source citation specified below. The following source citation is to be used when citing this datset: "LDEQ Landset Seven TM Mosaic of Louisiana UTM15 NAD83, (2002)."

Process_Description:

Each multispectral scene was subset to bands 3,5,7 and arranged in RGB-753 order. Each multispectral 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 imagery was mosaiced.
