INITIAL STUDY ASSESSING THE SUITABILITY OF DRONES WITH LOW-COST GNSS AND IMU FOR MAPPING OVER FEATURELESS TERRAIN USING DIRECT GEOREFERENCING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Drone technology has shown the potential to act as the middle ground between satellite, light aircraft, and terrestrial or in-situ methods. However, featureless terrain such as water poses a challenge when it comes to drone mapping. The main challenge is

GeoPick: Georeferencing Made Easy [PDF]
Biodiversity Information Science and Standards, 2023 GeoPick is a new web application aimed at providing a simple yet powerful georeferencing tool to the natural history collections community (Fig. 1). Its conceptual foundation is based on the Georeferencing Best Practices by Chapman and Wieczorek (2020), whose guidelines it intends to implement.

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 ...

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 ...

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.

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 ...
