North Arrow Research developed the RAVE suite of tools.
Part of what makes RAVE useful is that layers are added to the map using consistent, meaingful symbology that has been carefully developed by the Riverscapes Project Curators Team based largely in the Utah State University Ecogeomorphology and Topographic Analysis Lab.
For a complete list of curators and developers and their contributions, see Github RiverscapesXML Repository.
RAVE development has been funded primarily by the Bureau of Land Management and Anabranch Solutions. BLM has supproted the development of ArcRAVE & WebRAVE. This support has been through co-operative agreements between BLM and Utah State University, with subawards to North Arrow Research.
