Geographical means to do with the earth's features and places. Where things are, and what the land is like.
It attaches to location, spread, features and boundaries, so a geographical spread of cases and geographical features are both standard. There is a useful phrase in geographical constraints, meaning limits imposed by where somewhere is. The shorter form geographic means the same and is commoner in American English. The subject is geography, which splits into physical geography and human geography.

From geōgraphicus + -al. by surface analysis, geography + -ical. geography comes from Middle French géographie, from Latin geōgraphia. From Middle French géographie, from Latin geōgraphia, from Ancient Greek γεωγραφία (“a description of the earth”), from γῆ (“earth”) + γράφω (“write”). a doublet of geographia. Use in reference to lavatories derives from the mid-20th century euphemism "show one the geography of the house" in reference to pointing out the toilets.
