LiDAR is a remote-sensing technology that uses laser pulses to measure surfaces and objects in three dimensions. Millions of data points are collected from a sensor that can be mounted in a variety of aircraft and ground-based mobile platforms.

LiDAR is the predominant method for county-wide topographic mapping and elevation modeling in Missouri. The technology has changed the way elevation data is acquired and processed, and has made topographic data more accurate and affordable.


Available LiDAR imagery for Missouri

LiDAR data for Missouri is hosted by the University of Missouri and Washington University.  This map shows the extent of available data as of March 2020.  Missouri’s LiDAR is blend of QL1, QL2 and QL3. These quality levels (QL) help users assess the usability of each level for a particular purpose.  Levels identify both accuracy and spacing between the points, with QL1 being the highest level .  The majority of the LiDAR data for Missouri is at QL2. 


If you are familiar with LiDAR and want to directly access the download tool for LAS data, you can access this through the LAS Download Tool.

This LAS Download Tool is hosted at the GIS Clearinghouse.

This is no state-wide sponsored LiDAR program in Missouri. Missouri relies on federally sponsored programs for most LiDAR data.
