DEM (DSM/DTM/nDSM)

Our digital elevation models are built from our own data. With a resolution from 5 cm they offer a detailed and reliable picture of the terrain, with or without objects. The models can be delivered in tiles or per region. They are ideal for applications such as volume calculations, terrain analyses, drainage studies and rooftop solar potential.

About this service

Product

Onze digitale hoogtemodellen omvatten nauwkeurige DTM’s (Digital Terrain Models) en DSM’s (Digital Surface Models), opgebouwd uit onze eigen data. Met een resolutie vanaf 5 cm bieden ze een gedetailleerd en betrouwbaar beeld van het terrein – met of zonder objecten. De modellen kunnen geleverd worden in tiles of per area bepaald door de klant. Ideaal voor toepassingen zoals volumeberekeningen, terreinanalyses, afwateringsstudies en zonnepotentieel op daken.

Format & Delivery

The elevation models are delivered via hard drive or FTP, in common raster formats and split into tiles as required. Delivery always takes place as quickly as possible, with a schedule clearly agreed in advance based on the scope of the project.

Our commitment to you

We always deliver our DEM models in the agreed formats, with full quality control, and according to a schedule that is clearly agreed in advance so you always know when the data will be available.

The value of our product

Complete insight into terrain and surroundings

With our DEM models you get a detailed picture of both the terrain and everything on it. Ideal for applications in spatial planning, infrastructure design, hydrology and volume calculations, where precision is crucial.

Realistic 3D analysis with nDSM

The nDSM (normalized Digital Surface Model) shows the actual height of objects above the ground surface, such as buildings, trees and infrastructure. This allows you to directly measure height differences, volumes and object sizes, which is extremely valuable for urban modelling, shadow analyses or AI-based object detection.

A reliable basis for calculating earthworks

DTMs are frequently used for calculating earthworks. They map terrain heights in detail and can be used to efficiently calculate how much ground needs to be moved. This ensures smooth execution, cost savings and minimal surprises on site.
