Thank you so much for your video! I've been struggling with multiple tutorials, all attempting to convert KML (not GPS) files in ArcMap, but mine consistently showed errors. Your video finally provided the clarity I needed. Much appreciated 🙏
when i add the 12.5 file to arc map it is imported correctly,, however i cant do fill and fill direction on it.. i can do hill shade or other function but the fill is not working keep giving me error... do you know why??

when you try to check DEM data, it actually say above it will autodownload The Shuttle Radar Topography Mission (SRTM) 3-arc second data, which has a spatial resolution of approximately 90 meters. are you sure this is 10m resolution or is it just the 2d imagery?
also, you have the option to change it to SRTM 1 arc which give you 30m accuray for free. please advise if you really are improving these 30m elevation data using satalite imagery or is it just an overlay like every other open source elevation map. I am new to this GIS stuff
This is not a sentinel processed DEM. As u selected the Digital elevation model option as "sentinel 3sec" and output as "DEM" in the Terrain correction table, it processed the srtm 3sec dem as a output. This is just an SRTM DEM.
Please, could you make a tutorial on how to calculate two hydrologic drought indices namely,, Standardized Streamflow Index (SSI) in R. Or the Lake Level Change Index (LLCI) in R. The SSI uses Streamflow data from a gaging station, while the LL CI uses the Lake water level data. I have searched online and I can't find any tutorial on this two aspect s of hydrologic drought. It will go a long way if you could make a video on this. Thank you for your contents
Hello Sir. This is quite helpful, I have been trying to use the SPEI 1.8.1 version to derive this plot, and the codes I got from Chatgpt and Stark overflow won't just work. Thank you very much
> library(forecast) Error: package or namespace load failed for ‘forecast’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): namespace ‘vctrs’ 0.4.1 is being loaded, but >= 0.5.0 is required In addition: Warning message: package ‘forecast’ was built under R version 4.1.3 can you please help solving this error.
I applied all the steps and got the file with a resolution of 10 meters as I explained in the form, but when I want to apply some operations to it, such as extracting the water network and river basins, this process is not completed and a number of errors appear. Is there a solution, thanks.
