For my Masters I am looking into elephant space-use and its effect on vegetation change. I have elephant GPS collar data and was going to use Google Earth Engine to obtain NDVI values. I would like to establish elephant space-use across a fenced area in the form of either areas most frequently occupied (at the pixel level) or pixels the most time was spent in. I would then like to use that data to determine whether any vegetation changes (recent NDVI as a percentage of long term average NDVI) are linked to the elephant space-use (i.e. to determine whether vegetation change is elephant-mediated). I have looked at methods such as UD and BBMM but was wondering if there were more suggestions out there? Ultimately the method I use for space-use needs to have an output I can use to compare it to the NDVI values. Thanks in advance!
