Thematic Mapper Simulator

This is a Daedalus AADS-1268 scanner that flies on the ER-2 aircraft and simulates the LANDSAT Thematic Mapper instrument, with slightly higher spatial resolution. The TMS is used for collecting data similar in application to data collected by the Thematic Mapper (TM) sensor including Earth resources mapping, vegetation/landcover mapping, and geologic studies. The sensor acquires the following 12 spectral bands:

Daedalus
Channel
TM
Band
Wavelength,
micrometers
1 A 0.42 - 0.45
2 1 0.45 - 0.52
3 2 0.52 - 0.60
4 B 0.60 - 0.62
5 3 0.63 - 0.69
6 C 0.69 - 0.75
7 4 0.76 - 0.90
8 D 0.91 - 1.05
9 5 1.55 - 1.75
10 7 2.08 - 2.35
11 6 (High Gain) 8.5 - 14.0
12 6 (Low Gain) 8.5 - 14.0
