Choose “Insert”, click “New Map” and next “New Local Scene”. Next, the 2D map window can be used as the basis of a 3D scene with the DEM raster. Adding a basemap is a good idea to place the image in its spatial context. Now, the satellite image is visible in the map window and the Contents pane. You can add the orthophoto to your map by selecting the file in the Catalog window and clicking “Add to new project”. Next, you can create a new map by clicking “Insert” on the ribbon interface.

This can be brought into ArcGIS Pro by adding a folder location in the Catalog pane. Let’s suppose you have a geotagged orthophoto of a specified area, such as a multi-band raster image in jpeg format. To create a DEM, you can drape a 2D raster file over Esri’s elevation data in a 3D Scene.

Examples are the freely available DEMs of the USA’s National Elevation Dataset (NED) or the USGS 3D Elevation Program (3DEP). It’s also possible to bring in other elevation data with a different resolution. For example, ArcGIS Pro offers access to the World Elevation Services when creating a new 3D Scene as a default data source for displaying elevation data. Examples are viewsheds, elevation profiles and hillshade rasters.ĪrcGIS Pro users can create DEMs and derivates with imagery files containing height information. There are many variations of DEMs, with a wide range of applications for many disciplines. There are two main types of elevation models: DEMs, which are raster datasets depicting the earth’s topography as a regularly spaced grid, and triangular irregular networks (TINs), which connect irregularly spaced elevation points with triangular surfaces. Elevation models are a data type that can be derived from satellite and aerial imagery. What are Digital Elevation Models (DEMs) and derivatives?Ī Digital Elevation Model is a raster whose pixel values represent elevations of a surface, most commonly the elevations of the ground. ArcGIS Pro makes it easy to create and visualize Digital Elevation Models (DEMs) and derivatives from raster data.
