DHI GRAS

With more than 50 years of existence and continued growth, DHI is an independent, private and not-for-profit organization based in Denmark, with 30 offices and about 1,100 full-time employees worldwide. We have helped clients in more than 140 countries solving their most difficult challenges in water environments.
DHI provides consulting services as well as software products/solutions, often involving bespoke Decision Support Systems (DSSs) with smooth integration of water-related data and modelling tools in resilient and robust IT environments. We are considered a commercial pacesetter for development and application of comprehensive state-of-art solutions within water resources planning and management.
DHI’s Earth Observation knowledge hub, DHI GRAS, was established in 2000. It is located at the Danish DHI headquarters in Denmark but has close ties and interactions with all the global offices. Through DHI GRAS, DHI can provide key expertise in satellite image and data processing for hydrology, water quality, environmental assessment and monitoring.  DHI GRAS has completed projects in over 75 countries worldwide and ranging from large scale mapping of river basins, biomes or ecoregions at the scale of up to several hundred thousand of km² to more detailed mapping of species and habitats based on Very High Resolution (VHR) data. Mapping is often done in interdisciplinary project settings in close collaboration with hydrologists, ecologists, biologist, coastal experts, decision makers, engineers etc. Consequently, DHI GRAS is used to adapting solutions to the specific needs of the user and the project context.
