They’re basically the digital equivalent of those cool 3D maps you might’ve seen as a kid, showing you the lay of the land. If you’re working with terrain data, you’re almost certainly using DEMs. Now,
How to identify feature from multiple layers in QGIS?
Hiking & ActivitiesDigging Deep: Identifying Features Across Layers in QGIS QGIS, that trusty open-source Geographic Information System, is packed with tools. And one of the handiest? The ability to identify features even when they’re stacked on top of each other in multiple layers. Think of it like this: you’ve got a map showing roads, buildings, and underground
