The 3D Elevation Program Distributing Lidar Data in LAZ Format
In support of ongoing efforts to provide efficient, cloud ready, open data formats for the use of lidar data, the USGS National Geospatial Program and its associated 3D Elevation Program is transitioning all of its lidar data distribution files to LAZ format by September 30, 2018.
USGS Releases New Web-Based Groundwater Model Visualization Tool
A new U.S. Geological Survey groundwater model visualization tool is now available to help users visualize the inputs and outputs of complex groundwater models across the country.
2018 Lidar Partnership Awards Announced
Collaboration continues to move the 3D Elevation Program forward.

The 3D Elevation Program – Flood Risk Management
Flooding is the leading cause of Presidential disaster declarations. On average, the water hazard has resulted in more than 80 fatalities and cost the U.S. nearly $8 billion annually.
Lidar Base Specification Version 1.3 Released
The US Geological Survey National Geospatial Program has released a new version of the USGS Lidar Base Specification that defines deliverables for nationally consistent lidar data acquisitions.
New 3D Measurements Improve Understanding of Geomagnetic Storm Hazards
Measurements of the three-dimensional structure of the earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms.
Reservoir Sediment Can be Used as Fracking Proppant
Instead of requiring costly dredging to remove sediment buildup behind water reservoirs and diversions, sediment from reservoirs in the Missouri River Basin could actually be used as fracking proppant feedstock, also known as frac sand, according to a recently published U.S. Geological Survey study.
Not All Arsenic Tests are Created Equal
The reliability of arsenic testing for drinking water in Minnesota depends on how and when well water samples are collected, according to a new U.S. Geological Survey and the Minnesota Department of Health study, which highlights ways to improve the accuracy of arsenic tests for private wells.
Water-Quality Monitoring Program Aids Restoration of Great Lakes
A new water-quality monitoring program, established by the U.S. Geological Survey, can provide scientists and managers with the best available data to help evaluate the health of Great Lakes ecosystems and improve water quality for recreation and commercial fishing.
Salinity Decreased throughout Upper Colorado River Basin Over Time
Salinity loads that originate from groundwater within the Upper Colorado River Basin have decreased from 1986-2011, according to a new U.S. Geological Survey study done in cooperation with the Colorado River Basin Salinity Control Program.
