Elevation data can come in the form of point (e.g. from LiDAR), digital elevation model (DEM), or triangulated irregular network (TIN). In this workshop we will focus on DEM and TIN. We will learn about each model and related data structure, their relative strengths, the kind of information they provide, and how to obtain downstream derived information. This is a lecture-style workshop and the primary focus will be about understanding the two models. However, we will also see examples in ArcGIS or QGIS

Participants should know GIS and be familiar with vector and raster data.
