A SYSTEMATIC COMPARISON OF DIRECT AND IMAGE-BASED GEOREFERENCING IN CHALLENGING URBAN AREAS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
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 measurements in a given reference frame while e.g.

Aridity could have driven the local extinction of a common and multivoltine butterfly

Ecological Entomology, Volume 48, Issue 1, Page 40-54, February 2023., 2023
Coenonympha pamphilus is a common, generalist, and multivoltine butterfly, widely distributed throughout the Western Palearctic. However, it has seemingly disappeared from the southeast of the Iberian Peninsula. We performed ensemble species distribution models to detect the environmental variables that could be limiting the habitat suitability of this

Georeferencing experiments with UAS imagery [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Abstract. Comparing typical airborne mapping systems with Unmanned Airborne Systems (UAS) developed for mapping purposes, there are several advantages and disadvantages of both systems. The unquestionable benefits of UAS are the much lower costs of equipment and the simple operation; though, the regulations to fly UAS greatly vary by country. Low cost,

Positioning in time and space: cost-effective exterior orientation for airborne archaeological photographs [PDF]

, 2013
Since manned, airborne aerial reconnaissance for archaeological purposes is often characterised by more-or-less random photographing of archaeological features on the Earth, the exact position and orientation of the camera during image acquisition ...

A 2D Georeferenced Map Aided Visual-Inertial System for Precise UAV Localization [PDF]

2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2021
Precise geolocalization is crucial for unmanned aerial vehicles (UAVs). However, most current deployed UAVs rely on the global navigation satellite systems (GNSS) or high precision inertial navigation systems (INS) for geolocalization. In this paper, we propose to use a lightweight visual-inertial system with a 2D georeference map to obtain accurate ...
