How to update the attribute of a GeoDataFrame based on another database? I have a master GeoDataFrame with line features. I have another GeoDataFrame (say obs) which is a subset of the master geodatabase. My analysis regularly updates the obs. How can I write the results back to the master GeoDataFrame by matching geometry?
Can I do spatial join using geometry as the key?
GeoPandas documentation talks about spatial join by merging. How can I use this approach for updating my attribute values?
