raster map - when unavailable, you will

selection’
• TIP: check the basemaps for alternative
maps where feature selection may be
possible

14. 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.
