LiDAR / ALSM Data

Online LiDAR / ALSM data resources:

OpenTopography Portal - Our (ASU & GEON) internet-based LiDAR data distribution and processing portal.
USGS Center for LIDAR Information Coordination and Knowledge (aka CLICK) - USGS LiDAR point cloud distribution site
National Center for Airborne Laser Mapping (NCALM) online data distribution center - Clearing house for NCALM data.
NOAA Topographic Change Mapping LIDAR Data Retrieval Tool (LDART) - web-based application for accessing NOAA coastal change LiDAR data.
Puget Sound Lidar Consortium data access page - Access to PSLC topographic survey data and derived images

October 16, 1999 Hector Mine, CA earthquake (Mw 7.1) high resolution topography data set:

A portion of the Hector Mine Earthquake LiDAR data set is available for download below. An overview of the data set can be found on Ken Hudnut's (USGS) page at http://rincon.gps.caltech.edu/.

Detailed information about these data and their application is available in the Seismological Society of America (BSSA) Special Publication: The Hector Mine, California Earthquake of 16 October 1999:

High-Resolution Topography along Surface Rupture of the 16 October 1999 Hector Mine, California, Earthquake (Mw 7.1) from Airborne Laser Swath Mapping

Bulletin of the Seismological Society of America

Ken offers downloads of the complete data set via this directory. The directory contains 13 CDs worth of data, including all return files, derived contours, GPS navigation files and laser intensity files.

Hector Mine ALSM / LiDAR data downloads:

ascii return files:
We have made a subset of the ascii formated return files from the Hector Mine data set available for download. The files are grouped by flight line and zipped for quicker download:

Flight 01

(includes files 1041.txt, 1081a.txt, 1081b.txt)

Flight 03

(includes files 5121_03.txt, 5131a_03.txt, 5131b_03.txt)

Lake Tests Maneuvers

(includes files lake_01.txt and lake_03.txt)

Bulion Line

(includes files Bulion1.txt - Bulion5.txt)

Shapefiles:
We have converted the Hector Mine Maneuvers and Bulion ALSM return data to shapefile format for import to ArcGIS:

Flight 1

Flight 3

Bulion shapefiles

We have also performed a TIN interpolation of segment 5 of the Bulion line as an example of what these data look like once interpolated. This file is available in ESRI TIN format (for import to ArcGIS):
