I have a satellite imagery dataset called SEN12MS-CR. It contains Sentinel 1 (SAR) and Sentinel 2 cloudy and cloud free imagery in .tif format. Its split into 169 ROIs over the globe, with each ROI being split into patches. The dataset contains 122,218 patch triplets with 256x256 px size. I need to download a DEM for essentially every patch in this dataset. I there a way to do it that I'm missing? I've written a script that iterates over the whole dataset and uses py3dep library to download the DEMs, but its saying its going to take about 60 hours. I know its a large dataset, but given the fact that each DEM 'patch' would be approx. 5kb, it shouldn't take this long. Is there a better method that I'm missing?
