General Staff maps were created to meet the needs of the French military, who wanted precise maps to plan military operations. The general maps were produced by teams of surveyors who carried out land surveys via triangulation. These surveys made it possible to create the famous 273 maps at 1:80,000 and then the Type 1889 maps at a scale of 1:50,000 (other alternative versions and at different scales will also see the light of day).

The use of general maps has spread to other fields, such as scientific research, geography and cartography. Staff maps provided valuable information about the lands, villages and towns of 19th-century France, and became a valuable resource for researchers of local history and genealogy.
Today, mapping is based on advanced technologies such as geographic information systems (GIS), satellites and drones. Modern topographic maps are created from ground surveys, aerial photographs and satellite data.
In conclusion, general staff maps have played an important role in the history of France, cartography and geographical science in general. They provided valuable information on the French landscape of the 19th century and were the basis of French cartography for several decades. Although mapping technologies have evolved, general staff maps remain an important source of historical information about France and its past geography.
