Maps are visual representations of geography & they're tools for communication. By transforming complex spatial data into maps, cartography helps decision-makers, researchers, and communities see patterns, understand relationships, and make informed choices.

At the CGA, geospatial analysis is about revealing connections. By linking patterns in nature and society, spatial data becomes insight that drives better research, planning, and decisions.

Roger Tomlinson began work on the Canada Geographic Information System (CGIS), one of the first computerised GIS systems, a direct ancestor of modern #GIS.

#Thanks, Roger!

Beneath the Sahara lies a hidden world of #underground #rivers & aquifers, relics of a time when the desert was a savanna.

The largest, the Nubian Sandstone Aquifer System, spans Egypt, Sudan, Chad & Libya, leaving a reminder that even the driest places hold stories of #water.
