Techniques of Analysis (Pg 67-77)
• Cartography: The science of map-making.
o Primary purpose: To communicate information
o Closely integrated with analysis and less dependent on manual skills
• Scale is always indicated on the map (eg. Fraction, a ratio, written statement)
• Dot maps: useful to display data such as towns, wheat farming, cemeteries,
incidence of diseases, etc.
• Choropleth Map: Sacrifice detail for improved appearance.
• Isopleth map: consists of a series of lines
• Projection: How you can project a spherical earth on a flat surface.
Computer Assisted Cartography:
• Programs used to easily create mapping packages which deletes the need for artistic
skills and human error.
Geographic Information Systems:
• Geographic information system (GIS): Computer based tool used to store, analyze
and map spatially referenced data.
• Processing Hardware: Personal computer, may be used for large apps.
• Peripheral Hardware: May be used to input data, example: digitizers and scanners
• Software: Applications and programs
• Two principle methods of translation:
