Detecting Overlaps

Conceptual Model / Steps:

1. Define Driver
2. Define Datasource
3. Define Layer
4. Iterate over features in Layer
5. Get feature geometry
6. Assess for overlap each feature with every other feature

Easy Stuff

• previous examples demo up to Step 4

Ran out of time, lets look at the code

Next Steps

• speed! Problem could easily be processed in parallel
  • uvicorn
• look into using shapely or fiona
• bulk processing features instead of individually
• rtree module
• other?
