Dear fellows,
I will to compute land surface temperature(LST) from landsat etm imagery. Can the Landsat 7 ETM+ SLC-off data be used to compute land surface temperature because these products have data gaps ? thanks
Upcourse you can use Landsat to compute the land surface temperature
What is the accuracy you are looking for?
Landsat 7 has only one thermal band that can shows the thermal spatial variability on the earth. When you need more accurate estimation of surface temperature you need to rely on more thermal bands for atmospheric absorption correction.
I suggest that you refer to the following link for more information:
http://modis.gsfc.nasa.gov/data/atbd/atbd_mod25.pdf
It has a technical report of sea surface temperature derived from MODIS remote sensed data. You will find valuable information on how we can estimate surface temperature using thermal bands.
Good Luck,
Yes, you can but you should keep in mind that you are working with less precision
Yes you can. Google will point you to articles about this.

It is possible to use such data, anyway the gap fill algorithm provided for VIS , NIR and SWIR bands of ETM+ data shouldn't be used....
Dear Xuegang Chen
you can also use Modis MOD 11 product : MOD11C2 or MOD11C3 for Land Surface Temperature
Dear everyone,
I get some useful help. The Landsat 7 ETM+ SLC-off data gap fill algorithm shouldn't be used. Meanwhile, I want to ask how the surface temperature by landsat algorithm do accuracy assesment. Can I use MOD product to evaluate?
