In present day, topographic maps still serve their purpose: assisting with geographic planning, earth science studies and civil engineering. Database creators combined the information from those topo maps with other sources to create what became, by the mid-90s, user-friendly resources we now recognize when we access maps online.

In the 1980s, databases began to replace printed topo maps. Topographic surveys were then used for military and infrastructure-building applications. The first topographic map series of an entire country is known as the Carte g éom étrique de la France (1789).

Topo surveys were created in series to serve as the basis for larger topographic maps.
