Unmanned aerial vehicles (UAVs or ‘drones’) have become an essential tool for land surveyors. The geospatial industry is turning to drones to map the environment, which...

Unmanned aerial systems (UASs) include imaging systems and/or airborne Lidar systems on an ever-increasing number of variously sized, remotely piloted fixed-wing or multi-propeller...

its4land is an EU-financed project to assist Kenya, Rwanda and Ethiopia in mapping land tenure more quickly, cheaply and transparently. It will end in three years’ time; righ...

Today’s photogrammetric software is able to create dense and precise digital surface models (DSMs), digital elevation models (DEMs) and orthoimages. But is the accuracy suffi...

What is the best way to generate a high-precision 3D model to estimate the storage capacity of a lake that is surrounded by mountains? Rapid weather changes, low clouds and steep m...

Topographic mapping is a standard surveying task and the instrument of choice used to be a total station. The use of terrestrial laser scanning has become popular over the past dec...

UAS photogrammetry has been used to create a printed 3D model of the area around Tintagel Castle in Cornwall, UK. The model is on display in the new visitor centre at the castle. V...

Unmanned aerial systems (UASs) can be easily transported and this beneficial feature is ideal for photogrammetric surveys of remote spaces. Rapa Nui (Easter Island), the most isola...

Airborne laser scanning (ALS) offers a range of opportunities for mapping and change detection. However, due to the large costs typically associated with traditional ALS, multi-tem...

While unmanned aerial systems offer huge possibilities in modern farming, most of them lie in the future. These airborne vehicles currently mainly deliver images that are subsequen...

Irregular settlements, also known as 'villas' or 'favelas', present a big challenge in urban planning. When collecting data, whether to determine the existing situation or to plan...

In a recent project to obtain detailed and accurate orthoimages and 3D models to support technical staff in maintaining Prague Castle in the Czech Republic, the site was captured b...

Reconstruction and maintenance work in historical buildings such as churches requires detailed and accurate information about them, but it can be difficult and expensive to acquire...

When conducting surveys in countries near the equator, environmental conditions can be harsh. Heat, dust and humidity may disrupt sensitive equipment, while distrustful locals may...

Large corridor surveys, such as roads and railroads, used to be the domain of airborne photogrammetry or Lidar using conventional aircraft. In Turkey, it has been demonstrated how...
