Building Footprints

Pre-processing of building footprints data

Contents

Notebooks

Building pre-processing steps:

0. Shapely Validation and Checking Geometry Types
1. Fix Overlapping Buildings (merge or trim)
2. Fix Collapsed Buildings (merge or remove)
3. Snap
4. Split features

Code

• Downlaod_Footprints.py - Download building footprints data for a given city
• Check_Tess_Input.py - Run momepy.CheckTessellationInput and save data as parquets
• Explore_Issues.ipynb - Explore buildings on map
• Buildings_Berlin.ipynb - Explore Berlin Building Footprint data from OSM
• Fix_Overlaps.ipynb - Preliminary exploration of fixing overlapping buildings

Environment

conda env create -f environment.yml
conda activate py312_uscuni_buildingfootprints

Data

• OSM_Data - Geofabrik OpenStreetMap data (too large for Github)
• buildings.parquet - Building footprint data for Berlin (too large for Github)
• collapse, split, and overlap.parquet - Output of momepy.CheckTessellationInput for Berlin building footprints (footprints which may be prone to errors)
