This semester I gave a couple of lectures to the graduate students in University of Houston on water science. I was astonished to find out that several students are very interested in #DGGS #DGGRID for hydrologic research. The Q&A session was filled with in-depth discussions.

Justus made a great intro on using #DGGS through #xarray #xdggs at the #Pangeo showcase talk. Xdggs is now in a stage where you can use it fairly robustly with #HEALPIX and #H3. Other integrations like for #DGGRID are developed as separate plugins.

Using a discrete global grid system for a scalable, interoperable, and reproducible system of land-use mapping An accurate and timely land-use map of an area is a valuable geospatial dataset. Making one requires assembling heterogeneous geospatial input data. This becomes computationally expensive as the nu...

Great new paper in #BigEarthData on #DGGS practical application on #landuse mapping at #ManaakiWhenua #LandcareResearch New Zealand. While they used #H3 due to available tooling they described the generalisable methodology really well.

OGC requests Public Comment on candidate OGC API – DGGS Standard - Open Geospatial Consortium The candidate OGC API - DGGS Standard enables compliant APIs to retrieve geospatial data for a specific area, time, and resolution, based on a specific DGGRS, and also inquire which zones of interest ...

#DGGS #API is for a new and innovative way of sharing and indexing #geospatial data, that works with multi-resolution location identifiers across scales on the whole globe. API ergonomics are important for wide uptake and usability - open for feedback 🌍🌐💠 www.ogc.org/requests/ogc...

Discrete Global Grid System-based Flow Routing Datasets in the Amazon and Yukon Basins Abstract. Discrete Global Grid systems (DGGs) are emerging spatial data structures widely used to organize geospatial datasets across scales. While DGGs have found applications in various scientific d...

We recently made the first leap to apply our mesh independent flow direction model workflow to the DGGs. This will allow us to run hydrologic models on virtually any resolution supported by DGGs. #earth #hydrology #dggs #dggrid #GIS
