Sensor application - need a bit of help

[davo1234]

Hey guys, I've just started learning about remote sensing in university and I have found it fairly interesting to say the least.

I have this assignment where I have been given 5 applications and have assign appropriate sensors to it.

1. Discrimination of similar tree species based upon small differences in pigment content.
2. Mapping of single/multiple family residential housing (USGS level 3)
3. Regional mapping of exposed geological structures such as anticlines
4. Assessing continental-scale drought conditions.
5. Seas surface temperature mapping.

The sensors I can choose from include:
1. Landsat 7 ETM+
2. SPOT 5
3. NOAA AVHRR
4. Hymap
5. Quickbird

So far I believe for 4 and 5 NOAA AVHRR are the best choice. For 2 I have chosen quickbird and 1 and 3 Landsat ETM+.

Any opinions or suggestings where to go. I am having particular trouble with the geological application.

David.

David, do a forum search for the user 99thpercentile and ping him. I suspect he is your best bet on this forum.

1 is either Hymap or Quickbird, 2 is quickbird, 3 landsat 7, 4 could be SPOT 5 or landsat and 5 is NOAA.
