Hi, I have a sample DEM that has been generalized and filtered but keeping the sharpness of features. I have tried all filters i know but i couldn't replicate it. I would like to see if someone knows how to do it. Below are the links for the original and processed DEM: Processed: http://www.mediafire.com/file/1rv6nq3d3fwi6tp/filtered.jpg/file Original: http://www.mediafire.com/file/rn1jkbd06uwhkr4/original.jpg/file   Thanks in advance Stuart

Hello, As part of a project requested by the University where I study, I was asked to detect the temporal progression of a cork oak forest (Maamora in Morocco). To do this I turned to the NDVI index but I do not know the values of a pixel of cork oak forest concerning this index. So, I turn to you to give me an interval for the NDVI of the cork oak or why not another indicator that would better detect this kind of forest.

I don't have experience with Geoserver, but I think you may want to try OAuth to create user specific credential. The users who use to login usually invokes the same unique url from the system, which is common for many websites. The user then may save that credential in the browser cookie if they like. Using that same unique credential with the WFS link might be an overkill, since you can already track and limit the resource usage of that WFS link. This is a kind of question suitable for gis.stakexchange though.

Dear Experts.. Anyone has experience on generating WFS links based custom key authentication on a particular users with their keys using ARCGIS tools..instead of username & password.. Thank You

thanks yousef!
