Hydrological Modelling

Longitudinal and cross-section profiles can be produced with DTMs, land survey or a combination of the two. Topographic and textual information can be added for hydrodynamic modelling work.

Infrastructure Networks

Water and sewerage networks and attributes are collected by Blom by means of levelling planimetric measurements with GPS receivers from a topographic network designed for this purpose.

Aerial Imagery Control Points

In order to achieve accurate aerial imagery and DTMs a network of ground control points need to be precisely determined by GPS measurements and subsequently validated for cadastre.

Stereo Restitution

When photogrammetric imagery cannot be interpreted Blom’s experienced Survey staff carry out field measurements with survey quality GPS or electronic EDM systems.
