Prepare Embedded Python with GIS Packages for Windows

Download Python

• download Windows embeddable package (64-bit)
• unpack to a folder, eg., d:\misc\python-3.9.13-embed-amd64

Get PIP for Python

• download get-pip.py from here
• move to your python folder
• open command prompt, change to your folder
• open python39._pth in text editor and uncomment import site, save
• run python get-pip.py

Install GDAL and Fiona

• download and install Visual Studio Build Tools (if not yet installed)
  • select "Desktop development with C++"
• download the wheel file for (unofficial) Fiona binaries from here, eg., Fiona-1.8.21-cp39-cp39-win_amd64.whl
• download the wheel file for (unofficial) GDAL binaries from here, eg., GDAL-3.4.3-cp39-cp39-win_amd64.whl
• download the wheel file for (unofficial) GDAL binaries from here, eg., hdbscan-0.8.28-cp39-cp39-win_amd64.whl
• move both wheel files to your Python folder
• install with python -m pip install GDAL-3.4.3-cp39-cp39-win_amd64.whl Fiona-1.8.21-cp39-cp39-win_amd64.whl hdbscan-0.8.28-cp39-cp39-win_amd64.whl

Install SpatiaLite

• download sqlite-dll-win64-x64-xxxxxxx.zip
• rename sqlite3.dll to sqlite3.dll.bak
• unpack content of zip file to your Python folder
• download mod_spatialite-5.0.1-win-amd64.7z
• unpack content to your Python folder

Note: Reason why we overwrite sqlite3.dll is because creation of the spatial enviroment fails with updateTableTriggers: "no such module: rtree".

Install Packages

• create requirements.txt, for example:

geopandas
geojson

• run python -m pip install -r requirements.txt

Verify

• run python -c "import geopandas;" (no error should occur)
