Georeferenced Dynamic Event Handling [PDF]
, 2015 A fast and efficient response to hazardous events can make the difference between life and death. Using this necessity as premise, surveillance systems are evolving, increasing the number of sensors used in event detection and developing new methods and algorithms for events handling.

A georeferenced river quality model [PDF]
Water Science and Technology, 2001 Water quality models have reached a high degree of sophistication, but their weak side remains user interface and output georeferencing. The aim of this paper is to propose an interfacing procedure between two widespread but specialised programming environments: ArcVIEW as a Geographical Information System (GIS) and Matlab as a scientific programming ...

Automatic Georeferencing of Astronaut Auroral Photography [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2016 Abstract. Astronauts on board the International Space Station have taken thousands of high resolution, colour photographs of the aurora which could be made useful for research if their pointing information could be reconstructed. We describe a method to do this using the starfield in the images, and how the pointing can then be used to georeference the

Comparison of Distance Discrepancies in Georeferenced and Non-Georeferenced Terrestrial LiDAR Models
EPiC Series in Built Environment, 2021 The objective of this study is twofold: (a) To investigate the magnitude of errors introduced by a typical georeferencing procedure when it is applied to a relatively large (five acres), non- georeferenced, but still accurate point-cloud model. The modeled area is a commercial site, and its model was generated via static terrestrial LiDAR.
