I was going to ask the #Earth #Observation community, including @EOMasters, if there were good online resources to access and process #DigitalElevationModel (DEM) data.

But just found out that my ace colleague @LukeDataManager had done a detailed workflow and published it online.

Note to self: be more like Luke and publish my workflows

“LiDAR or Light Detection and Ranging is an active remote sensing system that can be used to measure vegetation height across wide areas.
This [tutorial] page… introduce[s the] fundamental LiDAR (or lidar) concepts including:
• What LiDAR data are.
• The key attributes of LiDAR data.
• How LiDAR data are used to measure trees...”

“A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”
