WebMerging Data. There are two ways to combine datasets in geopandas – attribute joins and spatial joins. In an attribute join, a GeoSeries or GeoDataFrame is combined with a regular pandas Series or DataFrame based on a common variable. This is analogous to normal merging or joining in pandas. In a Spatial Join, observations from to GeoSeries ...
