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.
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 ...
Geospatial intelligence can play a fundamental role in communicating the economic cost of climate change in the 21st century. With more availability of spatial resolution, the environmental effects of...
The presence of drones for aerial mapping on construction sites is steadily growing. This is mostly due to the benefits of drones and how they help ensure construction projects go according to plan. T...
A new measurement system is being developed to evaluate night-time road lighting and safety conditions based on luminance-calibrated 3D point cloud data. This new approach integrates imaging photometr...
