These days, it is quite common for people to use the rasterio, rasterstats, numpy, ... some of these packages are dependent on gdal. The easiest way to get started is to use Anaconda to create a new environment: conda create -n raster python=3.7. conda install -n raster gdal.
This is a known issue of rasterio in conda. As a workaround, from the anaconda prompt, try setting the GDAL_DATA environment to a path which contains a gcs.csv file (use search to find a path). set GDAL_DATA = C : \ Users \ johan \ Miniconda3 \ pkgs \ gdal - 2.1 . 3 - py36_vc14_7 \ Library \ share \ gdal \ gcs . csv

GDAL allows this by defining in-memory raster files. These are normal GDAL datasets, but that don’t exist on the filesystem, only in the computer’s memory. They are a convenient “scratchpad” for quick intermediate calculations. GDAL also makes available a function, gdal.ReprojectImage that exposes most of the abilities of gdalwarp. We shall combine these two tricks to carry out the reprojection.

I am attempting to install the rasterio package. I read that I need to first install the appropriate GDAL file, so I downloaded GDAL-3.1.4-cp37-cp37m-win32.whl (and also rasterio‑1.1.8‑cp37‑cp37m‑win32.whl). I am running Windows 10 and have Python 3.7 (the program file says Python37-32) that I use through Wing IED 101 6.1.

Using the "https://" identifier downloads the metadata at rasterio.open (). The use of Window () within read should (for supported datatypes) only download the data within the window. Instead, you can see that this usage actually takes much longer than downloading the entire data.
