Grey scale hillshaded DEM image showing glacial landforms in central Ireland.

Having just discovered that it is #WorldLidarDay (thanks to @watershedlab.bsky.social), I'm celebrating with a hillshaded DEM of the Clara Esker (part of the Eiscir Riada), central Ireland, formed between two ice lobes during ice retreat. Other glacial features in the image are.....1/2

It's #WorldLidarDay today and so here's a gorgeous airborne lidar Relative Elevation Model of the Elbow River in the Weaselhead Flats area of Calgary. #piewpiew 🧪⚒️ #mapchat #GIS #maps #geosky
