Extrinsic Map

An extrinsic map is a type of map that incorporates external data or symbols that are not inherently part of the geographic space but are added to enhance understanding, analysis, or visualization. These external elements provide additional context, comparisons, or abstract representations that support the interpretation of the mapped data.
