Anyone involved with structure-from-motion (SfM) photogrammetry has probably questioned which type of processing software is necessary for them to produce quality 3D point cloud data. Many SfM software packages exist...

Small and medium-format cameras are increasingly gaining popularity for mapping small and medium-size areas, corridors, construction sites and cities. They are also used as companions of Lidar systems, mounted on...

Phil Mills presents a case study of Derwent Reservoir in Northeast England, looking at the accuracy of photogrammetry underwater and surrounding the reservoir and at the value of the imagery...

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 sufficient for highly demanding railway applications?...

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...

Structure-from-Motion photogrammetry and GIS are being used to chart the success of a river restoration project in Northern England. Many of the world’s rivers are degraded as a result of...

At the start of this year, GIM International conducted a readers’ survey aimed at gaining a clear picture of the current state of the geospatial industry. With more than a thousand...

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...

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...

La planificación urbana se ha vuelto más complicada debido a la tasa actual de la urbanización y a la rápida expansión de las ciudades. Herramientas basadas en la Web en...
