A key feature of NetMap's synthetic river networks and virtual watersheds is the ability to customize various aspects of their design to meet your analysis and decision support needs. Adjust various watershed components to provide the best possible solutions.
A rigid delimited set of stream lines (or hydrography) may not be suitable for your project considering the great diversity of analysis and decision support needs in resource management, risk mitigation, restoration, conservation and research.
Another form of flexibility is that any information contained within NetMap's synthetic stream network can be transferred to other stream layers, including the NHD/NHDPlus, as needed (read more).
