• There are several types of vector data structures, with different levels of complexity (w.r.t. internal integrity checking) and compactness
• Understand node-chain-polygon topology (be able to draw a simple diagram) and how it helps detect topological inconsistencies
• With spatial data being inherently uncertain, a formal description of data quality is important: 5 components of a data quality report
• Geocoding in Geopandas(in geopy) can use different geocoding providers, with different results
