Our experience working with LiDAR has been varied and includes surveying transmission line surveys for infringement surveys, forestry and coastal mapping. We also provide ground control, quality control and post processing services for laser scanning work. We also own and operate a terrestrial laser scanner, capable of scanning up to 50,000 points per second and obtaining high accuracy measurements, please visit our terrestrial laser scanning website.

The image (right) shows Digital Elevation Model with aerial photography overlaid, hover your cursor over the image to see a contour model (shaded by elevation) that was created from the Digital Elevation Model.

We can process the LiDAR for analysis to best suit your requirements. For example, we can produce contour models, cross sections, maps coloured by elevation, reflectance, aspect etc...We can output the data in many formats for use in a variety of programs including AutoCAD or for use in a GIS. We can also analyse the data, for example by producing maps showing water flow directions and flood maps or by calculating volumes. Data can be exported as a file containing points for use in PLS CADD for example or we can process the data to view it as a 3D Digital Terrain Model. Digital Terrain Models can be enhanced by overlaying photography for realistic 3D renderings.

Merrett Survey Partnership have developed in-house software for processing LiDAR data. For example, we have developed our own software to remove foliage so that a 'bare earth model' can be created and are able to transform LiDAR data into any coordinate system.
