• Vector – points, lines and polygons

• Ratser – pixels with attributes

• GIS allows us to query and overlay data with

geographic coordinates

• “A map on top of a database”

• Everything happens somewhere

• Historical sources refer to place in many different

ways

• Associating exact location with these is complex

• Georeferencing

• Accuracy versus precision

• Relative versus absolute

e.g. roads, rivers

e.g. places

e.g. countries, territories etc
