Study Notes
Map Types
- Thematic Map: Emphasizes a specific theme or topic, showing spatial data distribution and patterns. Useful for finding correlations between data in different locations.
- Reference Map: Shows locations of geographical and political data. Used for finding places.
- Cartogram: Distorts land areas to represent variations in a value.
- Chloropleth Map: Uses different colors or shades to visually represent changes in a value across an area.
- Dot Distribution Map: Represents values using dots, with more dots indicating higher values.
- Graduated Symbol Map: Uses symbol sizes to represent values; larger symbols indicate higher values.
- Isoline Map: Uses lines to connect areas with the same value.
Distance and Direction
- Absolute Distance: Measurable distance using standard units (e.g., miles, kilometers).
- Absolute Direction: North, south, east, west.
- Relative Distance: Distance not measured in standard units, but rather in terms of time or perception.
- Relative Direction: Directions like "left," "right," "up," "down," or descriptions (e.g., "next to").
Spatial Patterns
- Clustering: Grouping of similar items or people close together.
- Dispersion: Spacing of items or people within geographic boundaries.
Map Projections
- Robinson Projection: Accurately shows size, shape, and distance of most regions, appearing globe-like. Less accurate at the poles.
- Mercator Projection: Shows true direction, good for navigation. Distorts area, especially at higher latitudes.
- Gall-Peters Projection: Shows approximately accurate area of continents. Distorts shape and ocean sizes.
- Polar Projections: Preserves direction and distances from the projection center. Distorts areas and shapes.
