I'm busy working on a project and I have orthorectified and atmospherically corrected SPOT5 images. We now need to create a point shapefile and then extract the spectral value of the cell at that ...
I'm using Grass 6.4.3 in Linuxmint 16. I don't have a very big problem but I'm trying to understand what is Grass doing, if I'm applying the process correctly and if there is something wrong with my ...
I have calculated at sensor reflectance for a multispectral image and preformed atmospheric correction. The reflectance values for the visible and NIR bands are between 0.2 to 0.01 for surface eg veg, ...
All, I'm working on a project using satellite imagery of a large braided river. I've been provide lots of SPOT5 images (that overlap). I've created a geodatabase, created a mosaic dataset, added the ...
Using the SPOT equation ρ = π L/[E cos (θs) d-²] to calculate TOA reflectance from Radiance. L was calculated using this equation [L = (X/A) + B] d was calculated by converting date to julian day ...
