Constructing Synthesizable Evaluations of Technical Interventions to Reduce Wildlife‐Caused Agricultural Losses 构建易用于证据整合的野生动物致农业损失缓解措施成效评估

Integrative Conservation, EarlyView.
A framework with eight key components to assess the effectiveness of technical measures to reduce wildlife‐caused agriculture loss. ABSTRACT Technical interventions to reduce wildlife‐caused agricultural losses (e.g., crops, livestock, and fisheries) are essential for human‐wildlife coexistence.

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.

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

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)

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.

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 ...

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.
