Remote sensing is all about gathering information on the earth using techniques that are ‘at a distance’ rather than touching the earth. Generally speaking remote sensing produces either point cloud data or imagery. The data is further processed using [geographical information systems] as part of [cartography].
Often Remote Sensing is differentiated by the type of platform or sensor used. Platforms can range from satellites through aircraft and drones to cars and ships. From a sensor perspective, Remote Sensing is a broad field that encompasses techniques such as [photogrammetry] and [lidar] but also [echosounding]. Often a form of ground truthing is required to transform the Remotely Sensed data into comprehensible products.
The Netherlands’ new Quality Assurance Act means that crews may be called on to prove they are building to plan at any point. For this, teams need to have a day-by-day overview of the project situat...
What will be the impact of beyond visual line of sight (BVLOS) on the application of drones in the geospatial surveying profession? At 'GIM International', we received this question from one of our re...
What if circling the Earth were as easy as going on a bike ride? Just imagine: the extraordinary, stunning views from orbit would be accessible to everyone with the same amount of effort as cycling th...
Increased focus on cloud computing and point clouds in the construction sector is expected to result in new levels of speed, collaboration and real-time communication. The construction sector is under...

To what extent will the smartphone become a professional mapping tool? Modern smartphones already contain many of the important functions to be used as mapping tools. However, whether they are suitabl...
Lidar mapping based on unmanned aerial vehicles (UAVs or ‘drones’) can generally be thought of as a close-range version of manned airborne laser scanning. In brief, lower mobilization costs and mu...
In June 2018, RSPSoc's 'Photogrammetric Record' publication devoted 11 pages to determining which term they would use for drones. They ultimately decided on ‘unmanned aircraft system’ or ‘UAS’...
Aerial surveys conducted in the UK and Ireland demonstrate the potential of a combination of nadir camera, oblique cameras and a Lidar unit in one to meet the need for accurate, detailed and up-to-dat...
This aerial acquisition mission in Greenland was made all the more challenging by the unique Arctic location. Precise geodata is considered vital to support almost all aspects of community activities ...
Read this interview with five pioneers in the field for insights into the best ways to introduce drones into your business model. Unmanned aerial vehicles (UAVs or 'drones') are increasingly becoming ...
A dense annotated ground-truth Lidar dataset of the city of Dublin is the first of its kind regarding the accuracy, density and diversity of classes. The hierarchical labels offer excellent potential ...
