TITLE: MULTI-SPECTRAL SCANNER (MSS) SATELLITE IMAGERY - 1990's

Geodataset Name:     MSS1991
Geodataset Type:     Image
Geodataset Feature:  Image

GENERAL DESCRIPTION:

These datasets contain satellite imagery collected from the Landsat series of satellites, using the Multi-Spectral Scanner (MSS) sensor. These MSS images are made up of 60m pixels.

RESOLUTION:                        60 meter

DATA SOURCE(S):                    U.S.G.S. EROS DATA CENTER, NORTH AMERICAN LANDSCAPE
                                   CHARACTERIZATION PROJECT.

SCALE OF ORIGINAL SOURCE MAPS:     N/A

DATE OF AUTOMATION OR SOURCE:      1991

GEODATASET EXTENT:                 State of Florida.  Certain counties may only have 2
                                   of the 3 dates available, due to lack of data or 
                                   extreme cloud cover for any given area.  Other images
                                   may have slivers of missing image data.  These are areas 
                                   where image data was unavailable for a given year, but 
                                   enough was available to warrant inclusion.

USER NOTES:

The MSS sensor captures image data in 4 distinct portions of the electromagnetic spectrum. Three of the 4 bands are represented here (4,2,1), rendering a false color infrared image. Band 4 is near infrared, bands 2 and 1 correspond to the red and green portions of the visible spectrum. There are 3 different MSS images available, one from 1973, 1986 and 1991, plus or minus one year. Instances where images are named mss70s, mss80s, or mss90s refer to the fact that multiple images were stitched together to form an image mosaic to cover the geographic extent of any given county. Though MSS satellite imagery is of relatively poor spatial resolution by today's standards, it is still a valuable tool for general landscape identification and classification, as well as temporal studies of change detection over time. The imagery may be used to view growth, urbanization patterns and land usage over the 3 decade time span. It can also simply be used as a background image on which to overlay other datasets.
