Lidar, primarily used in airborne laser mapping applications, is emerging as a cost-effective alternative to traditional surveying techniques such as photogrammetry. Lidar produces mass point cloud datasets that can be managed, visualized, analyzed, and shared using ArcGIS.

ArcGIS supports lidar data provided as LAS (or ASCII) files. There are three different formats (datasets) that can be used to manage and work with your lidar data in ArcGIS depending on your needs, which include the LAS dataset, terrain dataset, and mosaic dataset.

Like the public domain files from Tennessee's STS-GIS Services, lidar data can be used to generate a variety of useful information products, from elevation surfaces to 3D products. A brief introduction to what lidar data is and how it can be used. Use ArcGIS Pro to create and symbolize an LAS dataset.

This tutorial teaches how to use bare earth and first return lidar rasters to compare natural and cultural features in ArcGIS Pro. It uses data from previous ArcUser tutorials that was collected in 2017 during a public safety event sponsored jointly by agencies in the United States and Canada called the fifth Canada-United States Enhanced ...

Two common elevation models can be created by lidar, one using the highest return lidar points and the other one using the ground elevation points. A highest return surface includes tree canopy and buildings and is often referred to as a digital surface model (DSM).

To meet these requirements, some or all of the following tasks are commonly used to manage and share lidar data using ArcGIS: Manage your separate lidar collections using LAS datasets. Perform quality control (QC) checks to verify the lidar …

Organizations can make lidar point clouds accessible via the web by hosting the data on ArcGIS Online or your ArcGIS Enterprise portal. Users can then visualize the data using either the ArcGIS Online scene viewer in a web browser or using a custom web application.

Load the LAS dataset into a 2D map or 3D scene in ArcGIS Pro, then perform a visual review of the data to ensure noise has been properly classified, or use the editing tools to reclassify erroneous points.

Calculating the difference between bare earth and first return lidar rasters provides information such as forest canopy height and character, building heights and orientation, aboveground utility alignment, a count of cars on the road, and even esti-mates of large livestock in a field.
