NetMap review
Specialized GIS analysis for watershed, habitat, erosion, wildfire, and climate risks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NetMap is a watershed analysis and decision-support system from TerrainWorks Inc. It is designed for resource managers, conservation and restoration practitioners, researchers, consultants, and public agencies working at project, watershed, and landscape scales. The system combines virtual watershed datasets with tools for river networks, terrain, aquatic habitats, erosion, roads, wildfire, climate change, riparian zones, and watershed processes. It supports web and Windows environments through a hybrid cloud and desktop deployment model.
Its main strength is analytical depth within environmental and watershed work. NetMap supports fluvial process analysis, flow calculations, floodplain mapping, aquatic and fish habitat analysis, erosion and landslide assessment, debris-flow and sediment-delivery analysis, and road-related drainage and stability analysis. It also covers wildfire probability, fire intensity, climate-change forecasting, riparian zones, shade, thermal energy, and wood recruitment. Watershed delineation, risk analysis, data management, and Google Earth export extend its use from individual analyses to broader planning workflows. The ArcMap add-in, along with NHD and NHDPlus integrations, makes the platform a fit for teams already working with those datasets and tools.
NetMap uses contact-sales pricing rather than a free plan. Licensing terms describe annual subscriptions, with costs dependent on users and datasets. TerrainWorks also provides online data visualization services and runs analyses for clients, which may suit organizations that need specialist support alongside the software. The product is a strong choice for environmental teams that need detailed watershed, fluvial, habitat, erosion, wildfire, or climate analysis. Organizations seeking a general-purpose GIS, or teams that do not work with ArcMap and watershed datasets, should consider a broader platform instead.
NetMap pros and cons
- Where it wins
- Connects terrestrial and aquatic attributes in virtual watershed simulations
- Covers fluvial, habitat, erosion, wildfire, climate, and riparian analysis
- Integrates with ArcMap, NHD, NHDPlus, and Google Earth
- Where it doesn't
- Contact-sales purchasing requires an annual subscription
- ArcMap is required for the add-in tools
- Its environmental focus may exceed general GIS requirements
