Raster v Vector map data • Raster map data is a matrix of cells (or pixels) in a grid: – scanned maps, digital aerial photographs, satellite images, digital pictures. – geo-referenced, geographic coordinates of the location added. – useful as background for displaying other data. • Vector map data stores data on individual map features e. g. – Points such as train stations. – Lines such as railway tracks and rivers. – Polygons such as buildings or fields. – We can view, query and analyse vector map data.

Measurements • Available under Map tools • Measure distances or areas • Not possible to save the measurements or print on your map

Hillshading • Will be other overlays available in future
