I’ve been talking with NOAA and USGS to corroborate on the 3DEP Lidar availability.
When I started using the newest USGS 3DEP Lidar for Florida a month ago, I noticed the newest Lidar for Florida wasn’t lining up and finally figured out that they were using Albers projection.
I contacted Kirk Waters at NOAA and asked him if he could add the USGS 3DEP Lidar to their website which is much more flexible in the format downloads. He contacted Jason Stoker at USGS and between the two of them they made this corroboration happen.
Jason mentioned “they briefly considered using Albers CONUS scheme for 3DEP so that all data would be in a single CRS for the entire Country with a goal to offer transformations from Albers to whatever on the fly. The argument was that we were a National program, but were operating more as a clearinghouse, with dozens of different CRS and unit combinations across the US, which makes big-picture assessments and combining disparate datasets together more difficult. This effort was short lived, and the main champion of it left USGS, so we decided to revert back to having all data delivered to us be in the best local coordinate system. Unfortunately the Florida project of interest was one of those few contracted for as an Albers-only trial.”
I’m happy to announce the USGS 3DEP Lidar & DEM’s is now available on the NOAA Website in FL SPC systems, and NOAA will also be adding the New SPCS in 2022 when they become available.

notice the editors pick in the email that David Newcomer's summation from this year's Geospatial Summit hosted by NGS was featured. For you that may not know, David is an active member of the Geospatial Users Group and a retiree of NGS. He was the NGS Advisor for the State of Florida up until his retirement. David is an excellent representative of the group and has a great depth and knowledge of geodesy that is a substantial benefit to the Users Group, which is evident from his featured article. We are honored that he represented the Geospatial Users Group at the Geospatial Summit and his efforts are being showcased.
The role the members and officers of the Geospatial Users Group plays in the geospatial community is vital to necessary involvement in setting guidelines and policies for which we all will be impacted. You can be involved in this by joining or participating in the group. The group is made of volunteers who all have the goal of education and outreach, you can be a part of this process.
David Newcomer, PE, PLS, and former NGS Advisor for the State of Florida and Geospatial Users Group member and contributor offered to attend the meeting on behalf of the group this year. Mr. Newcomer submitted the following report regarding the Geospatial Summit below in the Download Section. He attended the 2019 Geospatial Summit on May 6-7, 2019.
Our members have wide-ranging backgrounds and career paths that made them become members of the Geospatial Users Group. We look to showcase our members and what background they have and how it benefits the group as a whole.
The group is comprised of a three member board, President, Vice-President and Secretary. They represent the members of the group and work on outreach. There are quarterly meetings held throughout the state of Florida with participation of those interested in the group.
The Geospatial Users Group is a group within the Florida Surveying and Mapping Society that was formed over 20 years ago as the GPS Users Group. Today with the convergence of so many professional uses of GNSS based applications the group was redefined as the Geospatial Users Group.
Join us at one of the upcoming quarterly meetings. Check the calendar for more information
