FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION
VERSION 2003, RELEASED NOVEMBER, 2002.
TITLE: ENHANCED THEMATIC MAPPER PLUS SATELLITE IMAGERY TRUE COLOR - 1999
Geodataset Name: TM99_TRUE Geodataset Type: Image Geodataset Feature: Image
GENERAL DESCRIPTION:
These datasets contain satellite imagery collected from the Landsat series of satellites, using the Enhanced Thematic Mapper Plus (ETM+) sensor. These ETM+ images are made up of 30m pixels.
RESOLUTION: 30 meter DATA SOURCE(S): Land Processes Distributed Active Archive Center (LP DAAC) SCALE OF ORIGINAL SOURCE MAPS: N/A DATE OF AUTOMATION OR SOURCE: 1999 GEODATASET EXTENT: State of Florida
USER NOTES:
The Enhanced Thematic Mapper Plus (ETM+) replicates the capabilities of the highly successful Thematic Mapper instruments on Landsats 4 and 5*. The ETM+ also includes new features that make it a more versatile and efficient. The ETM+ instrument is a fixed "whisk-broom", eight-band, multispectral scanning radiometer capable of providing high-resolution imaging information of the Earth's surface. It detects spectrally-filtered radiation in VNIR, SWIR, LWIR and panchromatic bands from the sun-lit Earth in a 183 km wide swath when orbiting at an altitude of 705 km. An ETM+ scene will have an Instantaneous Field Of View (IFOV) of 30 square meters in bands 1-5 and 7 while band 6 will have an IFOV of 60 square meters on the ground and the new band 8 an IFOV of 15 square meters. TMtr is represented here by bands 3, 2, 1 rendering a true color image. Bands 3, 2 and 1 correspond to the red, green and blue portions of the visible spectrum. TMfc is represented by bands 4, 3, 2 rendering a false color infrared image. Band 4 is near infrared, bands 3 and 2 correspond to the red and green portions of the visible spectrum.

DATA LINEAGE SUMMARY:
TM99_TRUE is an 8 bit version of the original 24bit image. This was accomplished using the advanced RGB algorithm available in ERDAS Imagine 8.5. This is an image mosaic from 1999 data.
