Discover the road sequences of bus lines using bus stop information and historical bus locations

International Journal of Distributed Sensor Networks, 2019
Discovering the road sequences traveled by the bus lines is of great importance for public transport management, such as bus journey time prediction and multimodal travel route recommendation, as the road sequence provides important information on ...

Quadrocopter localization using RTK-GPS and vision-based trajectory tracking

, 2011
This paper presents a method for trajectory tracking control and waypoint navigation of a quadrocopter using a vision-based camera system and an exact method for outdoor positioning using the Real-Time Kinematic Global Positioning System (RTK-GPS). First

Sharing landscapes with wildlife: Conflict and coexistence between high nature value pastoral systems and large carnivores

People and Nature, EarlyView.
Abstract High nature value (HNV) pastoral systems, that is those maintained by herding, transhumance and extensive grazing practices, are recognised as cornerstones of European biodiversity, cultural heritage and ecosystem service provision. Yet these systems are currently under significant pressure from a range of economic, social and environmental ...

Semantic Enrichment of GPS Trajectories

, 2012
Semantic annotation of GPS trajectories helps us to recognize the interests of the creator of the GPS trajectories. Automating this trajectory annotation circumvents the requirement of additional user input. To annotate the GPS traces automatically, two types of automated input are required: 1) a collection of possible annotations, and 2) a collection ...

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

Integrating habitat suitability, socioeconomics, and infrastructure to assess global biological invasion risk under climate change: A case study of the rice stem borer, Chilo suppressalis

Pest Management Science, EarlyView.
We developed an invasion risk index framework that integrates socioeconomic and environmental data using an entropy‐weighting method. The case study highlights the need for region‐specific biosecurity measures for Chilo suppressalis. Abstract BACKGROUND Biological invasion risk is a multifaceted concept that, according to the Food and Agriculture ...

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.
