Greetings to MAGIP -
The USGS recently released some more aerial LiDAR point cloud (LPC) and
original product resolution (OPR) bare-earth digital-elevation-model
(DEM) tiles for Montana.
New coverage is of almost 3,000 square miles consisting of portions of
Broadwater, Meagher, Judith Basin, Wheatland, Fergus, Golden Valley, and
Musselshell counties, including the communities of Buffalo, Judith Gap,
and Melstone.
A georeferenced PDF map showing the area of the latest releases is
available
here. The red area on that map was published on Wednesday 15
April 2026.
The data was collected during July and August 2023. These tiles are
Quality Level 2 (QL2) data, the base-level quality typically provided by
USGS.
Right now the lighter-green QL2 coverage area does not appear on the
images currently provided at
The National Map
Download and
USGS
_
LidarExplorer when you click on "Show" but that should
change in the next few days.
As of this writing (morning of Monday 20 April), neither of the generally
easy-to-use sources in the previous paragraph seem to have this new data
available. They usually have the data available for downloading
soon after release, before it appears on their respective maps.
If someone is anxious to begin using the new data, it is available from
the USGS Rockyweb server (step-by-step instructions are
here) and via Amazon Web Services (AWS - step-by-step instructions
are
here). On Monday 20 April 2026 both the LPC and OPR data was
available via both of those methods.
To facilitate use of those sources -
The project is "MT_Statewide_Phase5_D23"
The work unit is "MT_Statewide_P5_2_D23", both without the
quotes.
Product-level raster (GeoTIFF) one-meter 10-km x 10-km digital elevation
models (DEMs) are not yet available for this new data. Generally
USGS delays issuing new product-level DEMs until after all LPCs and OPRs
in a project are completed and released.
Finally, a reminder that if the USGS is not yet providing LiDAR point
cloud (LPC) or LiDAR-derived DEM data for your area of interest, the
Montana_Lidar_Inventory at the Montana State Library has and offers
LiDAR coverage not available from USGS. The Montana Lidar Inventory
also provides countywide mosaics as well as derived products such as
digital surface models (DSMs - including trees, buildings, etc.),
tree-canopy-height models, hillshades, contours, and building footprints
depending on the area.
