Welcome to the Lidar Base Specification online edition 

Historically, the Lidar Base Specification (LBS) was published as U. S. Geological Survey Techniques and Methods, book 11, chapter B4 (TM-11B4) with Hans Karl Heidemann as the primary author. In 2018, the USGS changed the review and approval method for updating the LBS and, concurrently, changed the publication method to make the updates more timely (see the Elevation Specifications Review Board page for more information). Along with these changes, the version of the specification was updated to 2.0. Version 2.1 of the specification was approved in September, 2019, by the USGS Elevation Specifications Review Board and the 3DEP Working Group.
