Maps

Spatial map types and their uses

Spatial maps visualise geographic data and spatial relationships.

If you have a spatial relationship you would like to represent, there is a map for that.

  • Choropleth Maps: best for displaying regional data like density or distribution

  • Heat Maps: best for identifying clusters and concentration patterns

  • Topographic Maps: Best for: elevation (contour lines) terrain and navigation

  • Dot Density Maps: Best for showing distribution patterns

  • Isopleth/Isoline Maps: Best for connecting points of equal value (temperature, noise etc.)

  • Flow Maps: Best for show movement patterns between locations( migration, trade)

  • 3D Maps: Best for adding height dimension to geographic data( terrain and complex spatial relationships

  • Example uses: Urban planning, geological studies, gaming environments

  • Digital Interactive Maps: Bets for complex data exploration and analysis (GIS, navigation apps)

Source 1. Particulate matter

 Particulate matter is coal ash and dust.

Coal dust can be released as ships are loaded and unloaded with coal.

Coal ash contains many toxic elements including, but not limited to, arsenic, cadmium, lead, mercury, and selenium.

Contaminants from coal ash can and do leach through the bottom of ash dumps and into groundwater, run off into surface water such as rivers and lakes, and dry out and blow over communities.
