Topic: overlay of velocity vector on study area
I am working on one of the glacier in India. I have trying to overlay the velocity vector on the subset image of study area but the I guess the direction of the velocity vectors are not oriented correctly, means some velocity vector are going uphill rather than coming down. What can be the possible error??
I have done image to image registration of the subset images of LANDSAT TM images then find the correlation. After that I masked the results whose SNR < 0.9.
