choropleth maps  

Definition

  • Choropleth maps can be described as the most commonly created thematic map type, in large part due to the relative ease of their creation using most GIS software packages and also due to the perception that they are easily understood. Choropleth mapping involves aggregating data to an areal unit of measure and then representing these data using color or pattern within the areal unit.
