To handle input data rates in the order of gigabits per seconds, programmable switch platforms are typically used, although they offer limited expressiveness. Recent solutions based on traditional SPSs, such as Storm and Flink, can support the definition of general complex queries, but they show poor performance at scale. In a softwarized network context, Stream Processing Systems (SPSs) can be adopted for this purpose. Implementing this mechanism requires the analysis of packet streams in a real-time (or close to) fashion. Upon critical event detection, corrective actions must be taken to keep the network running smoothly. The NHDplus allows for the communication of NetMap’s attributes and analysis results to the common national hydrography platform used for distributing data and modeling results across large and diverse stakeholder groups.One of the most challenging tasks for network operators is implementing accurate per-packet monitoring, looking for signs of performance degradation, security threats, and so on. 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.

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). TerrainWorks provides comprehensive analyses, ranging in scale from entire landscapes to watersheds to individual stream reaches, and is designed to be collaborative and accessible. 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. A GIS-based tool for linking field and digital stream data.
