We are experts in Digital Elevation Models (DEM) generation for flood modelling, hydrology and bathymetric projects. The Digital Terrain Model (DTM) and/or Digital Surface Model generated (DSM) are generated using LiDAR data and/or imagery. DIELMO3D provides the service of final products generation both from existing LiDAR data or imagery and new LiDAR survey.
Our experience and exclusive interpolation method for DEM generation allow us to offer customized and high quality products for bathymetry, hydrology and flood modelling among others.
DIELMO3D provides the service of high quality Digital Elevation Model generation generation (Digital Terrain Model & Digital Surface Model) for flood modelling and risk analysis. Thanks to our experience of more than 15 years in the field of LiDAR mapping and to our exclusive tools for custom products and developments, we are able to identify and correct most typical errors found on riverbed corrections (deformations, vegetation cleaning, noise removal, etc.)
The final result are optimal and custom Digital Terrain Models (DTM) and Digital Surface Models (DSM) for each hydrological analysis or flood modelling study. One of the most common products are DTM versions containing or not bridges and/or buildings.
Ocasionally, errors can be found on the riverbed due to the presence of water or riverside vegetation. These errors or problems may ruin simulations or hydraulic studies and have to be detected and cleaned. To solve this problem, DIELMO3D has developed a riverbed correction methodology, allowing to clean these errors and run analysis and bathymetric studies more efficiently.
To obtain the best possible accuracy in 3D models, both original raw data quality and LiDAR data processing methodology are important. Our exclusive interpolation method guarantees the use of the original data accuracy obtained by the sensor, interpolating only the points where there is no data.
In the image we can see how, to represent water bodies in the most realistic way, DIELMO3D classifies and interpolates them separately, avoiding potential errors on riverbeds.
