Hi all, my first post,
How do I apply atmospheric and terrain correction to SPOT 5 HRV?
I am using SPOT 5 HRV I have a dem and details of sun zenith and azimuth,
I have tried using i.topo.corr but I see the code is setup for landsat bands,
I get data not DCELL, I believe this to be floating point.
I have a floating point dem in the same coordinate system and resolution.
The values for gain and bias in the header are for
gain number for each band eg 5 5 5 3
absolute calibration gains 1.189124 1.612545 1.713030 6.289000
I assume to use these I need to re-write scripts? Advice?
The terrain differences are great across image 0- 2000m,
Approx 10S of equator, so I have a few clouds too.
Anyone provide assistance?
Cheers
Dave
