Global Subnational River Borders | Zenodo
Data » Vector
This dataset presents Global Subnational River-Borders (GSRB), a first global geospatial dataset of subnational, as well as national, political borders set by large rivers. GSRB incorporates three previous vector datasets (GAUL, GRWL + +, and WDBII) to map and quantify the use of large rivers as political borders at local (Level 2), state (Level 1), and national (Level 0) scales. When referencing this dataset, please use the full paper citation: Sarah J. Popelka, Laurence C. Smith; Rivers as political borders: a new subnational geospatial dataset. Water Policy 1 June 2020; 22 (3): 293–312. doi: doi.org/10....wp.2020.041

Software | Marxan
Software » GIS
Marxan is a family of software that can be applied to different types of planning challenges. Over the years, Marxan has grown from its standard two zone application to consider more complex challenges like incorporating connectivity, probabilities and multiple zones. Along the way, Marxan’s user community has also built plug-ins and interfaces to assist with planning projects.

SaTScan - Software for the spatial, temporal, and space-time scan statistics
Software » GIS
SaTScan™ is a free software that analyzes spatial, temporal and space-time data using the spatial, temporal, or space-time scan statistics. It is designed for any of the following interrelated purposes:
- Perform geographical surveillance of disease, to detect spatial or space-time disease clusters, and to see if they are statistically significant.
- Test whether a disease is randomly distributed over space, over time or over space and time.
- Evaluate the statistical significance of disease cluster alarms.
- Perform repeated time-periodic disease surveillance for early detection of disease outbreaks.
The software may also be used for similar problems in other fields such as archaeology, astronomy, botany, criminology, ecology, economics, engineering, forestry, genetics, geography, geology, history, neurology or zoology.

GitHub - dlgeorge/D-Claw: software for granular-fluid flows
Software » CAD for Remote Sensing
Software for granular-fluid flows. Contribute to dlgeorge/D-Claw development by creating an account on GitHub.
D-Claw is numerical software for modeling granular-fluid flows. It is built on top of Clawpack (clawpack.org), and is an extension and generalization of the shallow-water code GeoClaw (geoclaw.org), which includes algorithms for general shallow earth-surface flows. D-Claw solves a more general two-phase (granular-fluid mixture) model for landslides, debris flows, and lahars. D-Claw can also be used for simulating hybrid problems that involve the interaction of granular-fluid flows with bodies of water (eg., landslide-generated tsunamis, dam-breach floods, fluid or solid entrainment by inundating flows, such as debris-laden run-off or debris-entraining tsunamis). In the limit of vanishing solid concentrations, D-Claw results theoretically reduce to Geoclaw results (though details of the numerical imp
