Thematic Map
Emphasizes a specific theme or topic, key in Human Geography.
- Cartogram: Distorts land area to reflect changes in value.
Example: Population cartogram shows China and India with larger areas for higher population. - Choropleth Map: Uses shades to indicate value variations; darker shades show higher values.
Mnemonic: Think "CHORO" for colors. - Dot Map: Dots represent values; more dots indicate higher values.
Example: Each dot represents 200 farms. - Graduated Symbol Map: Uses symbols of varying size to indicate values; larger symbols represent higher values.
