NetMap Portal watersheds only cover a select subgroup of all NetMap datasets, primarily using LiDAR developed after 2017. NetMap provides derivation of detailed hydrography extending to the ephemeral and unchanneled portions of landscapes, connectivity and routing analyses, and advanced tools for resource management, risk mitigation and conservation, with transfer of that information to the NHDplus. Searches can be made to identify locations where two attributes overlap, like the highest 1 of coho habitat quality and the highest 10 of erosion potential.

NetMap applications include fish habitat mapping, floodplain delineation, road analyses, slope stability, riparian management and wildfire. NetMap also provides support in the form of (1) online technical help, (2) step-wise guides, (3) online mapping tools and a (4) community based approach to tool development and dissemination. Our goal at TerrainWorks is to make user-friendly GIS virtual watersheds and smart river networks available to agencies, NGOs, universities and the private sector. NetMap was created to provide off-the-shelf analysis capabilities in resource management, risk mitigation and conservation unavailable in other formats. TerrainWorks, with its flagship analysis technology “NetMap”, is being used by NOAA, US Forest Service, EPA, BLM, US Fish and Wildfire Service, Conservation NGOs, watershed councils, tribes, private sector, universities and internationally. NetMap can be built and applied anywhere in the world (Global Opportunity). Hostname1/IP address, Hostname2/IP address, Hostname3/IP address Host name Host name associated with the IP address. Doing so lets netmap checking succeed when the remote node connects to the local node using any of the possible outgoing IP addresses. TerrainWorks provides comprehensive analyses, ranging in scale from entire landscapes to watersheds to individual stream reaches, and is designed to be collaborative and accessible. The outgoing IP addresses are then contained in the local node netmap entry for that remote node.
NetMap’s unique set of virtual watersheds, analysis tools and online technical help, is designed to provide decision support in forestry, fisheries, restoration, riparian management, conservation, pre- and post-wildfire planning and climate change. It enables users to extrapolate survey results to unsurveyed streams by using GIS to estimate habitat abundance, potential fish abundance, or fish carrying capacity, for example. The output is a shapefile of survey reaches with both the survey data and attributes associated with the digitally produced stream layer (e.g., drainage area, gradient, and valley width). It hosts a climate change component that includes projected changes in seasonal hydrographs, changes in the likely location of snow-to-rain transition zones, and thermal loading. This tool based on a geographic information system matches stream-survey data to digitally produced stream layers created with NetStream software.NetMap contains models that allow the user to conduct analyses on various parameters that influence aquatic ecosystems such as wood recruitment, erosion sources, and potential habitat. Refer to NetMap Portal’s technical help and tutorial.A GIS-based tool for linking field and digital stream data. Valley width is calculated according to distance above bankfull depth. Searches can be made to identify locations where two attributes overlap, like the highest 1% of coho habitat quality and the highest 10% of erosion potential. text of NetMap, watershed-level controls on aquatic eco. Here users can pan, zoom in and out, and search for specific watershed attributes, like the best fish habitats, highest erosion potential, best riparian areas and widest floodplains, among other attributes.

The NetMap Portal, a free online mapping application, was developed to ease access and use of virtual watershed information in the form of maps. Thus, many people may have difficult accessing and using the wealth of watershed information contained in NetMap datasets.

Using ArcGIS requires adequate computer hardware, proprietary software and some experience. NetMap’s virtual watersheds work within an ArcGIS environment as a set of digital shapefiles, and contain information pertaining to river networks, channel environments, floodplains, riparian zones, erosion potential and roads.
