Our value-added layers are ready to use and can help you save time performing your geospatial analyses. Many of our value-added layers are non-licensed, built from our best-of-breed
NEXTMap data and easily available through traditional distribution methods or via our web services.
Our offerings include:
- Custom contours
- Terrain-derived hydrology dataset
- Terrain-derived coastline dataset
- Road and trail network
- Land steward boundary dataset
- Slope map
- Aspect map
- Hillshade image
Custom contours: enable you to perform profile analyses, elevation identification, slope modeling, or to create detailed maps. You can specify your contour parameters for interval, index line spacing, and level of detail.
Terrain-derived hydrology dataset: provides water bodies and double line drainages. With this dataset, you can perform more accurate flood, stream flow, and soil erosion analyses, and snowmelt runoff predictions.
Terrain-derived coastline dataset: represents coastal boundaries in your area of interest. You can use it in your coastal GIS applications for more efficient and correct analyses.
Road and trail network: displays transportation routes within GPS devices, GIS databases, and / or paper maps. The network covers roads, hiking and biking trails, and 4x4 tracks across the entire United States.
Land steward boundary dataset: shows public land areas (federal, state, and local boundaries) in the United States. This enhanced dataset enables you to display public land in a region, plan access routes to remote areas, and build initial site maps and recreational maps.
Slope map: represents the terrain’s degree of slope. This is useful for quick and effective slope analyses of the terrain.
Aspect map: displays the cardinal direction of the slope for effective terrain analyses. The aspect helps define the amount of sunlight striking the surface of the terrain.
Hillshade image: provides you with a more accurate and clear visualization of the topography. It is ideal for hiking applications, site planning, presentations, and plotting.
