LiDAR FLOOD RISK MAPPING

Generating the most accurate Digital Elevation Models for flood modelling and hydraulic studies since 2003.

Thanks to our in-house software for interpolation, riverbed correction and bathymetric profiles integration, Dielmo 3D transforms any existing pointcloud dataset into valuable LiDAR flood mapping productos and hydrological information ready to be used.

Digital elevation models (DEM) for hydraulics

Reliable Digital Elevation Models (DEM) and accurate LIDAR data are key for LiDAR flood mappping and modelling projects. Since 2003, Dielmo 3D provides the most accurate Digital Terrain Models for hydrological studies and flood modelling. We optimize our workflow and products to each project depending on available LiDAR data (from low point density /public data up to ultra-dense point clouds).

Riverbend correction in DEM

When it comes to carrying out a flooding and river flows study, the most important thing is to have the riverbed and its surroundings well defined.

To respond to this, in DIELMO we have developed specific and customizable algorithms to prevent the riverbed from closing on 3D models. In addition we integrate bathymetric profiles with LIDAR data to obtain a continuous model resulting from the fusion of both data sources (more info below).

INTEGRATION OF LiDAR BATHYMETRIC PROFILES

LiDAR topographic sensors are not capable of penetrating underwater. This translates into the absence of a LiDAR point cloud in the water bodies or in the measurement of the surface in the case of vegetation.

In certain hydraulic studies, it is interesting to incorporate into the two-dimensional model the real dimensions of the riverbed that remain submerged.

To solve this problem, in DIELMO we have developed our own LiDAR flood mapping methodology, to integrate bathymetric profiles made by classical topography into the LiDAR Digital Terrain Model (DTM), for an optimal riverbed correction.

The bathymetric profiles are interpolated in the direction of the river.
A new DTM is obtained by estimating the bathymetric dimensions from topographic profiles.
It ensures that the water does not run out of the channel due to interpolation problems.
The accuracy of the original LiDAR data is maintained in DTMs thanks to our unique interpolation method.

Benefits of working with Dielmo 3D

Confidence

Our systems have been tested and refined. We implement exhaustive quality controls at every step of production. This ensures 99.9% accuracy in power line inspection. Our production team is committed to working with our ISO 9001 quality standards.

Peace of mind

Our experience and production capacity in this type of project is your guarantee of compliance with deadlines.

Customization

Customization of the product to meet your specification. We are not limited by the constraints in of off-the-shelf software. Our R&D Department develops what our clients need.

Capacity

We are able to spin up additional servers on demand using parallel computing and our own software, if we need to meet very short deadlines. All in house.

Value

Our service is not the cheapest, but cheap service can be the most expensive if you are penalised for non-deliveries, unexpected errors, etc leading to the loss of the customer.

Flexibility

If you are an acquisition company and work seasonally, you do not need to maintain specialised staff all year round for processing. We are your contracted processing team.
