Multispectral search: Landsat 7 ETM, Landsat 4-5 TM, EO-1 and AVHRR


Using the EarthExplorer UI from the USGS, I did a search on the possible hit for multispectral imagery over the area of interest and the time of interest. This is what I found:


Enhanced Thematic Mapper Plus (ETM+)
Landsat 7
Wavelength
(micrometers)
Resolution
(meters)
Band 1
0.45-0.52
30
Band 2
0.53-0.61
30
Band 3
0.63-0.69
30
Band 4
0.78-0.90
30
Band 5
1.55-1.75
30
Band 6
10.40-12.50
60
Band 7
2.09-2.35
30
Band 8
.52-.90
15


For the area of interest and the period of interest, there are five images (out of 20 , the rest covers land)



  • Landsat 4-5 Thematic Mapper (TM) is a 30- to 120-meter multispectral data from Landsat 4 and 5. For the area of interest and the period of interest, there are nine images (out of 20, the rest covers land).

  • No hit for ALI or Hyperion on EO-1

  • Advanced Very High Resolution Radiometer about 20 hits, but the resolution is only 1 km.
