NASA Earth Observations (NEO)

Imagine seeing daily snapshots of climate and environmental conditions of Earth. NASA’s Earth Observations (NEO) is like a real-time climate snapshot of the world.

NEO focuses on 5 themes with 50+ global datasets, mostly climate-related. For example, data ranges from aerosols, chlorophyll to sea surface temperature. All are free GIS data sets that you can download in JPEG, GeoTIFF and Google Earth formats.

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: https://doi.org/10.2166/wp.2020.041

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.
