How does one combine random samples from multiple images to get single PCA matrix?

I have 10 multispectral landsat images each with 6 bands. I want to choose 2000 random samples from each image (total 20,000 from 10 images) and then want to apply Principle Component Analysis on...

Is anyone interested in reading about Tasseled Cap Transformation for Landsat 8?

TCT is a very useful index for estimating vegetation, albedo and wetness by using remotely sensed images. Recently a paper has been published about the derivation of these coefficients for...

What is the challenging issue in water mapping of lakes or rivers by using optical remote sensing data?

We are using MNDWI, NDWI, VIUPD and several indices to delineate water boundary from non-water features. We try to implement these methods for floods or lakes and try to choose some best threshold...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
