Retrieved snow depth in Mainland Norway (2018.10-2022.10) based on ICESat-2 ATL08 and DEMs
<h3><strong>Introduction</strong></h3> <p>This dataset's snow depth data was derived using elevation differencing, which is simply the snow surface elevation (ICESat-2 ATL08) minus the reference surface elevation (obtained from Digital Elevation Models):</p> <ol> <li><strong>DEM Co-registration</strong>: DEMs are co-registered to ICESat-2 ATL08 snow-off reference without vertical bias adjustment.</li> <li><strong>Elevation Bias Correction</strong>: The elevation bias between the DEMs and ICESat-2 is corrected using ICESat-2 ATL08 snow-off segments.</li> <li><strong>Snow Depth Calculation</strong>: Determining snow depth by subtracting <strong>the bias-free reference ground elevation(from Step 2)</strong> from ICESat-2 ATL08 snow-on segments.</li> </ol> <p>This dataset is presented in a tabular format, which simplifies the preprocess for machine learning models. While co-registration has been done (1), users have the flexibility to train a bias correction model again (2) and retrieve snow depth measurements anew (3). Alternatively, the snow depth can be directly used for various analytical purposes. Detailed methodologies for the co-registration, bias correction, and snow depth determination are thoroughly documented in the paper (under submission) to support users in leveraging this dataset for their research needs.<br> </p> <h3><strong>Meta Information</strong></h3> <ul> <li><strong>Study Area</strong>: Mainland Norway</li> <li><strong>Acquisition Period (ICESat-2)</strong>: October 2018 to October 2020</li> <li><strong>ICESat-2 data source</strong>: ATL08 (level3, version 5)</li> <li><strong>Reference DEMs</strong>: Norway DTM1, Norway DTM10, Copernicus GLO30, FABDEM.

Topobathymetric DEMs of Short Prong marsh and tidal flat in Hog Island Bay, VA 2022-2023
Seamless DEMs of the marsh edge and tidal flat at Short Prong in 2022 and 2023 were created using a combination of aerial photogrammetry and boat-mounted single-beam echosounding. Aerial photogrammetry surveys of the subaerial intertidal flat and marsh edge were completed during low tide using a DJI Phantom 4 RTK drone. Positioning was determined using six surveyed ground control points and drone on-board RTK. During high tide, a single beam echosounder was used to survey six cross-shore transects of the subtidal and one alongshore transect near the marsh edge. The same flight plan and echosounding survey path was used both years, with surveys taking place on 7/19/22 and 7/11/23. Photogrammetric data was processed in Agisoft Metashape to produce a DEM and a photomosaic. Echosounding data was processed in Hydromagic and interpolated using the natural neighbor method in GIS. Overlap of survey extent between photogrammetric and echosounding DEMs were stitched together in GIS to create seamless DEMs with a cellsize of 3 cm from the lower elevations of the marsh platform into the subtidal flat for 2022 and 2023.
Subsample of the maximum Water Area Extent of Telangana Rainwater Harvesting System from Pléiades DEM
<p>Small Reservoirs maximum water area extent polygones composing the Rainwater Harvesting System over the Telangana state, South-India. Maximum Water Area Extent are elevation isolines selected by hand from Very High Resolution Digital Elevation Model (VHR DEM at 2 meters resolution) derived from pairs of stereoscopic Pléiades images at 50cm resolution (10.5281/zenodo.10403040). The selection is made to find the area that contain both MWAE derived from Sentinel-2 (10.5281/zenodo.10402199) and Landsat archives (Global Surface Water, <span><a href="https://doi.org/10.1038/nature20584" target="_blank" rel="noopener">10.1038/nature20584</a></span>) curated from rivers and big dams (10.5281/zenodo.10402096).</p>
2m resolution DEM based stereoscopy Pleiades acquisitions in Telangana, South-India
<p>Four steroscopy pairs of Pléiades images (Pléiades © CNES 2021 Distribution AIRBUS DS) were acquired over Telangana state in 01 and 14 of June 2016 and the 16 of June 2019 and licensed to CESBIO by Airbus. The Pléiades Digital Elevation Model is a derivative product subject to the CC-BY-NC 4.0 license preventing commercial use. The four .tif files correspond to these DEM at 2m resolution. The dates were selected because the Rainwater Harvesting System small reservoirs of the areas covered were empty. Elevations within small reservoirs are thus equivalent to a bathymetry. We verified that 2 meter resolution is very adapted to retrieve the geometries of narrow and steep dikes that dam each small reservoirs.</p>
DEM and associated kinematic GPS coordinates of September 2009 survey of the salar de Uyuni, Bolivia
<p>This dataset consists of two parts: 1) the post-processed kinematic GPS coordinates of a September 2009 survey of a 45 x 54 km region of the salar de Uyuni, Bolivia. 2) a digital elevation model (DEM) of the salar de Uyuni surface derived from those kinematic GPS data.</p> <p>Details of the survey design are identical to that from an earlier survey in 2002 and can be found in the manuscript, "Topography of the salar de Uyuni, Bolivia from kinematic GPS" (doi: 10.1111/j.1365-246X.2007.03604.x). The DEM is described in the manuscript "A Terrestrial Validation of ICESat Elevation Measurements and Implications for Gloval Reanalysis" (doi: 10.1109/TGRS.2019.2909739). The DEM was generated from fitting two-dimensional Fourier basis set with parameters: L_x = L_y = 70000 meters, m = n = 10. This results in a basis set with a nominal resolution of 7 km.</p> <p>The attached "salar_de_uyuni_2009_dem" files duplicate Figure 1 from the authors' "A terrestrial validation of ICESat elevation measurements and implications for global reanalyses," whose caption is: </p> <p>Landsat image of the salar de Uyuni, showing ICESat tracks 85, 241, 360 and 1320 (red) and the GPS-derived DEM from 2009 (color-coded with respect to mean elevation). The portion of each track plotted in Figure 2 is boxed in black. Total relief on the GPS DEM is less than 1 m over 50 km.</p>

Digital Elevation Model (DEM) of the Duplin River and adjacent intertidal areas near Sapelo Island, Georgia
Topographic and bathymetric data were collected for the Duplin River and adjacent intertidal areas near Sapelo Island, Georgia, using high-precision multibeam SONAR equipment. The bathymetric survey was performed from 09-Dec-2009 to 12-Dec-2009. This study was conducted to create a base map of bathymetry, morphology and physical habitat of the Duplin River, which is a primary study site of the Georgia Coastal Ecosystems Long Term Ecological Research (GCE-LTER) project.
Digital Elevation Model (DEM) of Doboy Sound at the mouth of the Duplin River near Sapelo Island, Georgia
The purpose of this study was to map the bathymetry of Doboy Sound near the mouth of the Duplin River adjacent to Sapelo Island, Georgia. This study extends a previous bathymetry mapping project conducted in 2009. The primary objective of the Duplin River project in 2009 was to provide data in support of understanding the sediment and water exchange process between intertidal areas and tidal creeks of the Duplin River. The Center for Marine and Wetland Studies (CMWS) surveyed the Doboy Sound using the Simrad EM3002D Multibeam Echosounder (MBES) in April 2011. A digital elevation model (DEM) was then developed based on the depth survey data.
Soja toasten auf dem Betrieb
<p>Die Sojabohne ist eine hervorragende Eiweissquelle für den menschlichen Verzehr und für die tierische Ernährung. Sie hat aber auch Verdauungshemmstoffe. Diese müssen vor einer Nutzung durch eine Hitzebehandlung deaktiviert werden. Das Toasten von Sojabohnen ist dafür ein mögliches Verfahren. In folgendem Video zeigen wir, wie die Verarbeitung von Sojabohnen auf dem Betrieb von Johannes Edhofer funktioniert. Er baut selbst Soja an und verfüttert sie nach einer Aufbereitung auf seinem Betrieb an seine Legehennen.</p> <p>The second video ‘On-farm soy processing’, published on the <a href="https://www.youtube.com/channel/UCTelsVBJ4E2pRv9TXE7zycg">Legumes Translated Youtube channel</a>, provides a demonstration of the processing of soybeans on the farm of Johannes Edhofer, in Sankt Pöllten, Austria. Soya beans are an excellent source of protein for human and animal consumption. They also contain digestive inhibitors.These must be deactivated by heat treatment before use. The toasting of soybeans is a possible method for this. Johannes cultivates and processes soya himself and feeds it to his laying hens on his farm. </p> <p>The video, which was produced by Donau Soja and FiBL and is available in German with English, French, Romanian, Russian, Serbian, and Ukranian subtitles. It is the result of a collaboration of Legumes Translated and OK-Net EcoFeed. OK-Net Ecofeeed aims to help organic pig and poultry farmers in achieving the goal of 100% use of organic and regional feed.</p>
