Pilot LIDAR Project - Portland Metro Area

What is LIDAR?

LIDAR (Light Detection and Ranging) is a way to map the surface of the earth with more accuracy than ever before.

What is this pilot LIDAR project about?

The interactive map lets you compare the resolution of imagery generated with LIDAR with other kinds of mapping techniques such as 10-m shaded topographic relief (DEM), orthophoto, and topographic (DRG) maps (see images below for comparison). You can display additional overlays, such as tax lot outlines, streets, and five geohazard study maps. You can zoom directly to your address, if it is in the mapped area. Note that these pilot LIDAR project data are not intended for site-specific investigations. More background information.

What do I need to view the map?

To view the map, your browser must be JavaScript enabled, and if you are using Internet Explorer, allow ActiveX controls. The map itself is image intensive. Users with slower internet connections may find that resizing the browser window to a smaller size will help the map image load faster. If you are unfamiliar with online map tools, please read the help file first. Access the interactive map using one of the methods to the right.
