Laying the Foundation for Location-Based Decisions
Elevation Data to Suit Your Needs
Intermap’s 3D foundation data layers provide the framework necessary for governments and businesses to make informed decisions and find intelligent solutions to their planning challenges. We provide up to 1-meter resolution elevation products in our NEXTMap Elevation Data Suite. Our comprehensive elevation data offers some of the most homogenous imagery and accurate elevation products on the market at a global scale.
Superior Value
Global Coverage – NEXTMap is available for all countries and locations worldwide
Rich Features & Bare Earth Models – NEXTMap is available as a natural terrain feature digital surface model (DSM) and as a bare earth digital terrain model (DTM)
Hydro Enforced – Water bodies and coastlines are flattened and corrected for accurate measurement
Seamless Dataset – NEXTMap delivers seamless coverage free of blunders, seam lines, or spikes that can be visible in other global datasets
Reliable & Cost Effective - Intermap’s budget-friendly fusion services support use of high-res data in high-value areas like cities or flood plains, while providing wider area coverage from medium-resolution datasets
Convenient Access – Datasets are available through our web portal or via API
In addition to creating baseline and custom elevation content, our solution creates products that derive from elevation content, including normalized DSMs, slope and aspect maps, hillshade, contours, topographic maps, flood models, and hazard maps for anything from earthquakes to landslides. It is also suitable for extraction of drainage network and hydrology data, 3D roads, infrastructure models and vegetation information.
Additional Services and Analytics
Profile. Accurate point-to-point terrain profiles anywhere in the world. Profiles can be run over either a DSM or DTM with features, such as buildings and tress, removed. Profiles consist of 3,000 points over any distance across a city or across an entire continent.
Viewshed. Perform visibility analysis from 1km to 100km in radius, clearly showing obstructions. Viewsheds can be run over either a DSM or DTM with features, such as buildings and trees, removed.
Point Values. Fast results for up to 20 locations at a time, showing height above sea level, height of vegetation, land cover, slope, and aspect.
Clutter/Land Classification. Streamlined land classification shows colorized profile and includes both clutter type and height. Clutter type information is classified into categories including bare earth, light and heavy vegetation, urban, roads, and water.
Contour Maps. Contour maps show an alternative view of our DTM data, providing a visual aid to elevation identification, slope indication, or to create detailed maps. Contours are available off-the-shelf at 10m intervals, but custom contours can be created for your area of interest (AOI).
