*Abstract: *The U.S. Geological Survey (USGS) National Geospatial Program
(NGP) Lidar Base Specification Version 1.0 was published in early 2012, and
revised as Version 1.1 in 2014. The notable revisions in version 1.1 were
definitions for 3D Elevation Program (3DEP) Quality Levels, alignment with
the American Society for Photogrammetry and Remote Sensing Positional
Accuracy Standards for Digital Geospatial Data, updating the delivery
format to LAS version 1.4, and clarification of several requirements. The
version 2.0 update will further align with new industry standards and best
practices, define requirements for additional 3DEP products and services,
and address new lidar technologies.

As a cooperative effort of the 3DEP and the National Hydrography Dataset
(NHD) program, the NGP is developing a common data dictionary for both
topographic and hydrologic breaklines. The goal is to enhance the
integration of the NHD and 3DEP elevation products by enabling the use of
common linework to the highest degree possible. This data dictionary is the
most exciting update to the specification. Although 3DEP lidar projects
require only minimal hydrographic breaklines to be collected for
hydro-flattening, those features will be consistently formatted and
immediately usable by the NHD as well.

This presentation will preview the changes from version 1.1 to version 2.0
and provide an opportunity for attendees to have questions about the
specification answered.
