Our
NEXTMap digital elevation data can help you make critical water resource and floodplain management decisions. The data is current and wide-area, allowing you to perform water-related analyses with a single, seamless digital elevation dataset across your entire area of interest (local, region, country, and watershed boundaries).
In addition, our
digital elevation data is hydro-enforced to ensure that structures over water bodies (such as bridges and culverts) are removed, water surfaces are flat, and watercourses flow downstream – resulting in reliable representations of drainage basins for detailed slope and flow analyses.
Use our
hydro-enforced digital elevation data for more accurate and cost-efficient ways to:
- Create flood maps and perform flood risk assessment
- Determine watershed boundaries and sites for hydraulic structures
- Perform hydrological analyses
- Address environmental planning issues
- Plan and monitor water resource projects
Risk Management Solutions
Our digital elevation data enables more accurate natural hazard risk evaluation and control. Use our data for efficient flood modeling, portfolio analysis, insurance rating, and more. Web-based tools for underwriting and accumulation control are also available via our Risk Assessment Portal.
Floodplain Mapping in the U.S.
Our NEXTMap digital elevation data is also a potential source of data to satisfy the FEMA guidelines for accuracy and density for low and medium risk specification levels within watersheds.
Value-added Layer: Terrain-derived Hydrology Dataset
We also offer a hydrology dataset that provides water bodies and double line drainages, enabling more accurate flood analyses.
