UK-based geospatial mapping specialist, GeoSLAM, has expanded its mining offering, building on its world-leading reputation in the sector to provide advanced underground mining solutions. The news follows the unveiling of...

The mission: capturing 21 quarries in 60 days. Squeezed into that timeframe were planning and performing the UAV photogrammetry flights, editing the RAW images, processing the data, extracting the topography using Virtual Surveyor, and production of the orthophotos, Digital Surface Model (DSM), Digital Terrain Model (DTM) and contour maps for each site. The main client, a government institute, needed highly precise and reliable 3D models and maps fast, as well as data their engineers could work with in a CAD environment. “There was a lot of pressure because of the short timeline”, said Nuno Santos, owner and CEO of Aerisurvey, a Mangualde, Portugal-based company specialized in high-precision UAV surveying.

The Irish Department for Agriculture, Food and the Marine (DAFM) has awarded Getmapping a contract to supply new high-resolution aerial photography and digital height models for the Republic of Ireland....

An inertial navigation system (INS) is a critical part of a surveyor’s armoury. The measurements provided by the INS, including heading, pitch/roll, timing and absolute position, ensure that surveyors can confidently measure their environment, safe in the knowledge that every area and angle is covered precisely.

Trimble and Amberg Technologies have entered a collaboration to provide a tunnel survey solution. The combined hardware and software solution will enable construction, mining professionals and surveying service providers in...

A new INS from Oxford Technical Solutions aims to break new ground in bringing high-quality navigation data to the Lidar surveying industry. Launched on 22 March 2021, the xNAV650 promises...

Is it possible to enhance point cloud accuracy and density by merging Lidar with photogrammetry technologies? Lidar data can penetrate trees and measure shadow areas to produce a very accurate...

The technique known as structure from motion (SfM) has been suggested as a valid alternative to traditional photogrammetric methods. In a project in Glasgow, UK, an RTK-based point-to-point validation technique...
