Accuracy assessment of high-resolution terrain data produced from UAV images georeferenced with on-board PPK positioning [PDF]

open access: yesJournal 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

Comparison of Distance Discrepancies in Georeferenced and Non-Georeferenced Terrestrial LiDAR Models

open access: yesEPiC 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.

A georeferenced river quality model [PDF]

open access: yesWater 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 ...
