The videos linked below provide information on elevation topics such as 3DEP products and services, and how to use 3DEP data in various software applications.
In this lesson, you will learn about the lidar products available through the 3D Elevation Program (which is abbreviated as “3DEP”). The lesson will introduce 3DEP, discuss the lidar data available, and where to find the data.
Lesson 10A - 3DEP Topic Lesson: Digital Elevation Models, Hydro-Flattening, Hydro-Enforcement, and Breaklines In this 3DEP Topic lesson, we will provide information on different types of Digital Elevation Models, or DEMs.
The following series of lessons will cover how to use LiDAR data in the ArcGIS Pro environment. In this lesson, we will provide the user with an overview of how to load and view lidar files in the standard LAS format in both 2D and 3D.
This lesson will cover additional lidar point cloud processing and analysis features in ArcGIS Pro. If necessary, please review lesson 10b1 for guidance with importing LAS files, filtering, and visualizing lidar point cloud data in ArcGIS Pro.
By the end of this lesson, you will be able to create and utilize a shapefile area of interest to subset LAS files, create a LAS Dataset with multiple LAS files, generate and export raster surfaces and contours derived from the lidar point cloud, and visualize the data in a 3D scene.
Global Mapper is a software package for visualizing, analyzing, manipulating, and exporting a wide variety of GIS data. By the end of this lesson, you will be able to open LiDAR point cloud LAS data files in Global Mapper, turn on all or specific LiDAR point Classes, visualize the data in 2-D and 3-D, and change the visualization using toolbar functions.
This lesson will cover additional LiDAR point cloud processing and analysis features in Global Mapper.
By the end of this lesson, you will be able to load multiple LAS files, define and use a polygon area of interest to subset LAS files, and generate and export raster surfaces and contours derived from the LiDAR point cloud.
By the end of this lesson, you will understand the difference between the LAS and LAZ format, know where to download the laszip.exe tool, and how to decompress a LAZ file to a LAS file using laszip.exe. The USGS offers other lessons on using LAS files in ArcGIS Pro, Global Mapper, and LP360.
This video tutorial shows how to use the National Map’s 3D Elevation Program (3DEP) Elevation web service in ArcMap. By the end of this lesson, you will be able to add the Dynamic Elevation Web Coverage Service to ArcMap, enable raster processing templates, and retrieve a spot elevation.
This lesson will show how to run GRASS GIS and utilize GRASS’s unique user interface to import and visualize elevation data.
