The various types of data referenced spatially in a GIS system are often referred to as "layers".

Similar to an Overhead Projector, with a series of transparencies laid upon it.

A map is an abstraction from reality, to inform us about

some aspect of reality.

Spatial Data

3 Major types of data:Boundaries (and other vector) data• Counties• Local Authorities• PCTs• LSOARoad networksBackground mapping (raster) data• 1:50,000 colour raster map• Points• Postcodes (e.g. NHS Postcode Directory)

Making Maps

Things to Remember• It must be clear what is being shown on the

mapsColours:• Avoid red & green together (colour-blindness)• Choice of colours may prejudice interpretation

Making Maps

Classifications and ranges• Don’t choose too many (or two few) rangesThink about how these are classified:• Is your choice justified, or is the map a kind of

LIE?What about your choice of area unit?
