Base maps are the building blocks of cartography, serving as the foundation upon which other thematic maps are built. They typically display the physical features of a geographic area, including topography, land cover, and transportation networks, and provide a reference point for adding additional layers of data.


  • Providing a consistent reference point for all other map layers
  • Allowing for accurate spatial analysis and modeling
  • Facilitating effective communication of geographic information
  • Supporting decision-making processes by providing a visual representation of geographic features
  • Enabling the integration of various types of data, such as demographic or economic information, with geographic features
  • Enhancing situational awareness for emergency responders by providing a detailed view of the terrain and transportation infrastructure
