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 remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality las...
Dr Pascal Sirguey had waited two years for this day and took a few final minutes to savour the moment. It was a sunny morning in early 2017, and students, historians and scholars had gathered in Arras...
Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by su...
Culturally rich Canyons of the Ancients National Monument, Colorado, are managed by the Bureau of Land Management as an integral cultural landscape containing a wealth of historic and environmental re...
A Brazil-based architecture firm benefited from using innovations in GeoSLAM’s handheld scanners, enabling site teams to complete a survey four times faster than by using traditional methods. To pro...
The arrival of airborne Lidar, also referred to as airborne laser scanning (ALS), has revolutionized area-wide 3D data acquisition of topography, bathymetry, vegetation, buildings and infrastructure. ...
Archaeologists have been studying the Sand Canyon Pueblo in Colorado, USA, for decades. Today, painstaking traditional mapping and visualizations no longer suffice for detailed studies. A survey combi...
Reality 3D models, Lidar points clouds, superhigh-resolution aerial imagery and artificial intelligence from aerial imagery… these are just a few of the products derived from aerial mapping that the...
While it is positive news for our industry that the use of unmanned aerial vehicles (UAVs or ‘drones’) is continuing to increase, the rise has brought with it a key question: how do we ensure that...
Since the last autonomous underwater vehicle (AUV) review in 2016, the market has continued to grow. The biggest market for AUV systems remains the military. The world’s most advanced navies own and...
Wetlands are essential ecosystems which provide numerous benefits to society as a whole. But their functionality strongly depends on the hydrology and topography of the watershed, thus creating the ne...
Telecommunication operators are working at full speed to bring the 5G network to life. Most operators are currently at the signal propagation planning stage and are defining optimal locations for the ...
In the German geospatial industry, there is a longstanding platform for open and constructive dialogue with researchers but also informal talks and discussion in between. It is called the Oldenburger ...
Could drones form the missing link between aerial imaging and terrestrial data capture? Aeroscan's Mark Nicolai believes so, as he explains in this interview. There have been rapid advancements in unm...
DGI 2019 followed the pattern of previous years with a subtitle of Geospatial Intelligence for National Security and with similar themes, the main ones being collaboration, integration and partnership...
