What is the difference between cartography and GIS?

The key issue between cartography and GIS is that cartography is concerned with representation while GIS is concerned with analysis of spatial relationships. GIS is a product of the development of computer-assisted cartography, which generated geo-referenced spatial digital databases.

What tools are used in cartography?

Cartographers frequently use digital cameras and scanners in addition to satellite images to capture visuals for a map. They may utilize drafting equipment, such as lighting tables, straightedges, stencils, lettering aids, drafting scales, T-squares, protractors and dividers, to sketch and develop rough drafts.

What are the 3 types of maps?

Notwithstanding the actual medium of the map (e.g., our fleeting thoughts, paper, or digital display), maps represent and describe various aspects of the world. For purposes of clarity, the three types of maps are the reference map, the thematic map, and the dynamic map.
