Accuracy assessment of high-resolution terrain data produced from UAV images georeferenced with on-board PPK positioning [PDF]
Journal of the Bulgarian Geographical Society, 2023 In recent years, unmanned aerial vehicles (UAVs) have increased rapidly and successfully established themselves as a tool for the rapid collection of high-resolution images as baseline data in land cover studies and topographic mapping. In photogrammetry

Evaluation of georeferencing [PDF]
Proceedings of the 6th Workshop on Geographic Information Retrieval, 2010 In this paper we describe a georeferencing system which first uses Information Extraction techniques to identify place names in textual documents and which then resolves the place names against a choice of gazetteers. We have used the system to georeference three digitised historical collections and have evaluated its performance against human ...

Methods for FMCW radar map georeferencing [PDF]
ISPRS Journal of Photogrammetry and Remote Sensing, 2013 Abstract In a context of mobile environment mapping, a vehicle-based radar system, K2Pi, has been developed. A mapping of the environment is carried out from the radar datasets. Given the specificities of radar maps, the main problem at this stage is to find a method to georeference these maps.

Understanding collective human movement dynamics during large-scale events using big geosocial data analytics [PDF]
Computers, Environment and Urban Systems Volume 87, May 2021,
101605, 2021 With the rapid advancement of information and communication technologies, many researchers have adopted alternative data sources from private data vendors to study human movement dynamics in response to large-scale natural or societal events. Big geosocial data such as georeferenced tweets are publicly available and dynamically evolving as real-world ...

Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Arthropod biomass is a key element in ecosystem functionality and a basic food item for many species. It must be estimated through traditional costly field sampling, normally at just a few sampling points. Arthropod biomass and plant productivity should be narrowly related because a large majority of arthropods are herbivorous, and others ...

DIRECT GEOREFERENCING OF UAVS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Abstract. UAV systems have become an attractive data acquisition platform in emerging applications. As measuring instrument they extend the lineup of possible surveying methods in the field of geomatics. However, most of UAVs are equipped with low-cost navigation sensors such as GPS or INS, allowing a positioning accuracy of 3 to 5 m.
