Acquiring geospatial data in GNSS compromised environments remains a problem in mapping and positioning in general. Urban canyons, heavily vegetated areas, indoor environments represent different leve...
Pleiades 1A and 1B are twin optical satellites of Optical and Radar Federated Earth Observation (ORFEO) program jointly running by France and Italy. They are the first satellites of Europe with sub-me...
Image-based mobile mapping systems enable an efficient acquisition of georeferenced image sequences, which can be used for geo-data capture in subsequent steps. In order to provide accurate measuremen...
Unmanned Aerial Vehicle (UAV) data acquisition is more flexible compared with the more complex traditional airborne data acquisition. This advantage puts UAV platforms in a position as an alternative ...
The use of rational functions has become a standard for very high-resolution satellite imagery (VHRSI). On the other hand, the overall geolocalization accuracy via direct georeferencing from on board ...
Efficient mapping from unmanned aerial platforms cannot rely on aerial triangulation using known ground control points. The cost and time of setting ground control, added to the need for increased ove...
The options available for orientation of satellite imagery in cases requiring optimal metric precision are generally rational functions, where the RPCs are provided by the image supplier, or a rigor...
GeoEye-1 was launched in September 2008, and after some five months of commissioning commenced commercial operations in February, 2009. With its 0.41m panchromatic and 1.65m multispectral resolution...
High resolution stereo satellite imagery is well suited for the creation of digital surface models (DSM). A system for highly automated and operational DSM and orthoimage generation based on CARTOSAT...
In recent decades, photogrammetrists have been exploring the georeferencing approaches that can improve consistency, completeness, and reliability of referenced spatial information. In this paper, an...
Due to the SAR1 geometry imaging, SAR images include geometric distortions that would be erroneous image information and the images should be geometrically calibrated. As the radar systems are side lo...
Over the last few years low-cost micro and mini UAV systems equipped with light-weight geosensors such as video cameras have started to appear on the market. These UAV systems are mostly instrumented ...
According to the principle of space intersection、collinearity equations and error propagation law, mathematical models of theoretical accuracy of direct georeferencing are proposed in this paper. The ...
In the years of 2004 to 2006, the Portuguese authority for forestry, the Direcção Geral dos Recursos Florestais (DGRF) ordered a digital photo flight over the whole country. The images, acqu...
There are many disasters happened because the weather changes extremely in these years. To facilitate applications such as environment detection or monitoring becomes very important. Therefore, the de...
