GeoFRESH (geofresh.org) is a platform that helps freshwater researchers to process point data across the global river network by providing a set of spatial tools.
Follow the tutorial or upload your csv-table that contains geographic coordinates. GeoFRESH allows you to
- map your points,
- move points to the nearest stream network segment,
- delineate upstream catchments of each point,
- extract a suite of environmental attributes across the catchment,
- and download the data for further analyses.
GeoFRESH is based on the Hydrography90m stream network. For more information, please visit hydrography.org.
For further analyses of your freshwater data, you can use the hydrographr R package that facilitates the download and data processing of the Hydrography90m data (publication in Methods in Ecology and Evolution, website with details and examples, source code on GitHub).
