A PRECISE POSITION AND ATTITUDE DETERMINATION SYSTEM FOR LIGHTWEIGHT UNMANNED AERIAL VEHICLES [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
In many unmanned aerial vehicle (UAV) applications a direct georeferencing is required. The reason can be that the UAV flies autonomous and must be navigated precisely, or that the UAV performs a remote sensing operation, where the position of the ...

Direct Georeferencing of a Pushbroom, Lightweight Hyperspectral System for Mini-UAV Applications [PDF]

Remote Sensing, 2018
Hyperspectral imagery has proven its potential in many research applications, especially in the field of environmental sciences. Currently, hyperspectral imaging is generally performed by satellite or aircraft platforms, but mini-UAV (Unmanned Aerial Vehicle) platforms (<20 kg) are now emerging.

Comparison of Direct and Indirect Georeferencing Methods Using Satellite Linear Array Iimages [PDF]

فصلنامه علوم و فناوری فضایی, 2015
Comparison of direct and indirect methods for georeferencing of satellite linear array stereo images is proposed in this paper. In direct method, collinear condition and orbital elements are used for geolocation of pixels and ground control points (GCPs)

Knowledge sourcing, geopolitics, and FDI: An empirical analysis on the US green and digital sectors

Global Strategy Journal, EarlyView.
Abstract Research Summary This paper examines how foreign direct investment (FDI) shapes firms' sourcing of knowledge in the digital and green domains under rising geopolitical frictions. We assemble a firm–country dyadic panel (2013–2020) linking US patent backward citations to firms' FDI, enriched with bilateral geopolitical distance and host‐country

Where were all the trees? Computer vision meets landscape history to unlock the potential of historical Ordnance Survey maps

People and Nature, EarlyView.
Abstract The first edition of the Ordnance Survey's 1:2500 County Series is marked with treed areas, such as woodlands and orchards, and, remarkably, freestanding trees. Consequently, it is an unparalleled source of information on the distribution of trees across Britain in the mid‐late nineteenth century, when the maps were first surveyed. In order to

Adaptive Re-weighted Block Adjustment for Multi-Coverage Satellite Stereo Images without Ground Control Points

IEEE Access, 2019
Georeferencing satellite imagery is the basis for mapping and other subsequent processing in photogrammetry and remote sensing. Traditional georeferencing methods, which require adequate and well-distributed ground control points (GCPs), are time ...

Spatio‐temporal patterns, associated factors and mitigation of tiger and leopard attacks on people in western Himalayas

People and Nature, EarlyView.
Abstract Coexistence with large carnivores becomes extremely difficult in areas where there are large number of attacks on humans. An understanding of the factors that explain the spatio‐temporal context of such attacks would guide policy and management to mitigate conflict, conserve carnivores and assist coexistence.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
