A new topobathymetric lidar dataset for the Potomac River from the 3D Elevation Program (3DEP) is available for download. Uses: estimating concentrations of contaminant plumes; engineering for bridges and roads; mapping aquatic habitats for biological assessments; and flood mapping.

Learned about this fun dataset on a regional IL GIS call recently.

sciencebase.gov/catalog/item/6

It's a point cloud of the River and Ship Canal, and it's detailed enough to spot cars!

7%  25% Of The Ocean Floor Mapped From 2017 (Seabed 2030)
--
seabed2030.org/ <-- @Seabed2030 web site

H/T Dennis Haines
“🗺 Did you know that in 2017, only 6% of the world’s seafloor had been mapped to modern standards? Considering the ocean spans some 70% of the Earth’s surface, that’s a significant gap!
But over the past five years since Seabed 2030 launched, we’ve been able to map almost 25% of the ocean floor.
By discovering more about the seabed, we gain a greater understanding of our environment and can ensure its protection. After all, we can’t protect what we don’t know…”

Made a map of the sea depth around Greece (deepest point SW of Peloponnesos = around 5100 m deep). Curious about the origin of the structures west of Kefalonia.

Pro tip for anyone who happens to be looking for high resolution and data. Nasa's publicly available images top out at 3.6k pixels wide, which might not be enough for say a detailed 3D model. But if you go to the web page where they're available e.g. neo.gsfc.nasa.gov/view.php?dat and click one of the download links, it actually renders the data live. So if you hack the URL you can dial up any* resolution you want.
The URL for the bathymetry data for example ends with `&format=PNG&width=3600&height=1800`. If you want an image with say, 10 times the resolution, just add a zero to both dimensions.
*Not sure what the upper limit is, or what resolution the original data set is. Don't abuse it or it might get taken away.

Satellite-derived bathymetry (SDB) with Sentinel-2A/B imagery retrieves depths down to 14 m with an average bias of 0.02 m and an average absolute error of 0.71 m compared to echosounder data multi beam

What Is A Digital Elevation Model (DEM)?- A Practical Guide
--
equatorstudios.com/what-is-a-d <-- shared tutorial
--
“A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”

spent 4 days in Eltanin Bay conducting a geological survey and selecting core sites. This area is largely unmapped and therefore a great chance to collect new hi-res bathymetric data! A major interest is to understand the geomorphic structures created by the ice flow.

Ronne Entrance is the southern entrance from Bellingshausen Sea to George VI Sound. Although it was discovered by Finn Ronne in 1940, only a few have mapped small sections in high resolution. contributes an area 5.5 times the size of in unprecedented detail.
