This book is your guide to 3D elevation technologies, products and
applications. It will guide you through the inception and implemen-
tation of the U.S. Geological Survey’s (USGS) 3D Elevation Program
(3DEP) to provide not just bare earth DEMs, but a full suite of 3D
elevation products using Quality Levels (QLs) that are standardized
and consistent across the U.S. and territories. The 3DEP is based on
the National Enhanced Elevation Assessment (NEEA) which evaluat-
ed 602 different mission-critical requirements for and benefits from
enhanced elevation data of various QLs for 34 Federal agencies, all
50 states (with local and Tribal input), and 13 non-governmental
organizations. The NEEA documented the highest Return on Invest-
ment from QL2 lidar for the conterminous states, Hawaii and U.S.
territories, and QL5 IfSAR for Alaska.
Chapters 1, 3, 5, 8, 9, 13, 14, and 15 are “must-read” chapters for
users and providers of topographic lidar data. Chapter 8 addresses
linear mode, single photon and Geiger mode lidar technologies,
and Chapter 10 addresses the latest in topobathymetric lidar. The
remaining chapters are either relevant to all DEM technologies or
address alternative technologies including photogrammetry, IfSAR,
and sonar.
As demonstrated by the figures selected for the front cover of
this manual, readers will recognize the editors’ vision for the future
– a 3D Nation that seamlessly merges topographic and bathymetric
data from the tops of the mountains, beneath rivers and lakes, to the
depths of the sea.
