Light Detection and Ranging
Light Detection and Ranging (LIDAR) sensors are laser radar sensors that measure ground terrain
elevations from airborne platforms and produce a very high resolution point cloud. These sensors
return data sets consisting of millions of 3D points and are capable of creating Level V terrain
digital terrain elevation data (DTED) images.
Lidar Explorer for ArcGIS is an extension to ArcGIS that enables GIS
users to work with Lidar data directly within their GIS system, and with their
other existing GIS data. The vast majority of ArcGIS functionality is
supported for the Lidar data. Lidar Explorer FCE provides access to Lidar
data as points in 2D and 3D environments. It does not convert or
represent the data as TIN or raster surfaces. If the user requires such
surfaces, standard ESRI tools can be used to produce them.
With the combined features of FCE and DME, Lidar Explorer for ArcGIS is
the most powerful and flexible Lidar tool available to ESRI GIS users
today. Its modular architecture allows for easy incorporation of future taskspecific
add-ons being developed for niche markets such as data providers,
researchers, forestry, urban analysts, military, intelligence, and homeland
security. License for Lidar Explorer for ArcGIS allows full use of both
modules.
The Lidar Explorer FCE module allows users to work directly with Lidar points as a point
feature class, enabling the application of virtually all ArcGIS functionality against the
Lidar data, including 3D visualization in ArcScene.

The Lidar Explorer DME module provides a specialized framework for managing, visualizing,
analyzing, and processing an entire project of LAS files as a single layer within ArcMap. DME
eliminates the difficulties of managing vast Lidar datasets in large numbers of tiles, and has been
tested with datasets of over 1.5 Billion points, spanning 4300+ tiled LAS files.
