Different types of Spatial Data:-
1. Geo statistical Data :-
• Points as sample locations ("field" data as opposed to "objects")
•Continuous variation over space
2. Lattice/ Regional Data :-
• Polygons or points (centroids)
• Discrete variation over space, observations associated with regular or irregular area I units.
3. Point patterns :-
• Points on map (occurrences of events at locations in space)
• Observation of a variable are made at location X
• Assumption that spatial arrangement is directly related to the interaction between units of observation
