What is a 'cartographic model' used for in GIS?

A cartographic model serves as a crucial tool in the field of Geographic Information Systems by illustrating the sequential processes involved in map production. This diagrammatic representation provides a visual workflow that outlines the various steps, methodologies, and transformations applied to raw geographic data to generate a finished map.

By using a cartographic model, GIS professionals can not only document the mapping process but also engage in effective communication regarding the methodology to stakeholders or team members. It helps in analyzing how different data inputs are manipulated or combined to yield a meaningful portrayal of spatial information. Therefore, the primary focus of a cartographic model lies in encapsulating and communicating the procedural aspects of map-making, which is vital for ensuring accuracy, consistency, and reproducibility in GIS projects.
