Across all industries, three common LIDAR survey data requirements are Digital Surface Models (DSM), Digital Terrain Models (DTM), and Contour Maps.
DSMs will include all surface features, including vegetation and man-made structures, whereas DTMs will represent the bare-earth land features with all of those surface features removed.
Contour Maps are often overlaid on top of a DTM, and will use break lines distributed systematically across elevations, in order to further understand the fundamental characteristics of the terrain in a survey area.
These three basic types of LIDAR map outputs will enable a wide range of further applications across industries, and are almost always basic requirements for any LIDAR survey project.
Pipeline and Power Line surveys cover long horizontal distances, which can often require different LIDAR drone technology for optimal results.
Vegetation encroachment is a common problem in management of these long assets, and LIDAR surveys are useful to locate areas where
vegetation is encroaching into the corridor beyond a tolerable limit – as well as to calculate the volume of vegetation that should be removed.
For Power Transmission specifically, LIDAR data is often used for Sag Analysis of power lines, to analyze the condition of the power lines,
as well as the proximity of the lines to nearby vegetation.
For Pipeline assets, LIDAR surveys are also useful to analyze land and soil changes, as well as any movement of the pipelines themselves – which can be significant over time.
LIDAR surveys provide high accuracy 3D data that is essential for volumetric calculations in Mining, Cement, Construction and Infrastructure.
Volumetric data requirements range from frequent stockpile calculations, all the way to advanced geotechnical analysis for massive earthworks and ground support systems.
Because LIDAR survey data provides valuable structural and volumetric information about a land area, other common requirements include land morphology and hydrological analysis, simulating water flows and other variable conditions across the survey area over time, and in certain scenarios.
With autonomous drone technology, LIDAR surveying is possible in even the most challenging and complex environments, including a wide range of functions in underground mining.
Structures that are essential for surveying in underground mines include: stopes, drifts, ore passes, slot raises, drill bores and ventilation shafts.
Halo Robotics has a unique specialization in underground mining and confined space drone technology, with significant operating experience executing LIDAR surveys and inspections in these high risk environments.

LIDAR technology makes it possible to quickly scan and digitize a 3D model of an asset,
and this can be hugely valuable to asset managers and EPC contractors,
which frequently require updated schematics and as-built models in order to construct or maintain an asset.
With LIDAR payloads that can be used as hand-held scanners or mounted to a drone,
we can quickly generate an accurate 3D model of the real asset, with flexible file formats
that can be used with any major CAD, BIM or planning software.
