This article addresses the problem of incorporating cognitively salient landmarks in computer-generated navigation instructions. On basis a review existing literature domain with landmarks, develops algorithms for generating routing instructions that include references to landmarks. The most basic algorithm uses new weighting model annotate simple routes A key novel feature this is it depends only on commonly available data and generic capabilities web mapping environments. suite extensions...
Storing, querying, and analyzing trajectories is becoming increasingly important, as the availability volumes of trajectory data increases. One important class analysis computing similarity. This paper introduces compares four most common measures similarity: longest subsequence (LCSS), Fréchet distance, dynamic time warping (DTW), edit distance. These have been implemented in a new open source R package, freely available on CRAN [19]. The highlights some differences between these similarity...
Computing trajectory similarity is a fundamental operation in movement analytics, required search, clustering, and classification of trajectories, for example. Yet the range different but interrelated measures can be bewildering researchers practitioners alike. This paper describes systematic comparison methodical exploration measures. Specifically, this compares five most important commonly used measures: dynamic time warping (DTW), edit distance (EDR), longest common subsequence (LCSS),...
Recent technological advances in geosensor networks demand new models of distributed computation with dynamic spatial information. This paper presents a computational model change regions (such as may be derived from discretizations continuous fields) founded on embeddings graphs orientable surfaces. Continuous change, connectedness and regularity are defined local transition rules used to constrain region evolution enable more efficient inference region's state. The provides framework for...
The paper investigates whether the methods chosen for representing uncertain geographic information aid or impair decision-making in context of wildfire hazard. Through a series three human subject experiments, utilizing 180 subjects and employing increasingly difficult tasks, this research evaluates effect five different visualizations text-based representation on under uncertainty. Our quantitative experiments focus specifically task uncertainty, rather than reading levels uncertainty from...
This paper presents a new technique for information fusion. Unlike most previous work on fusion, this explores the use of instance‐level (extensional) within fusion process. proposes an algorithm that can be used automatically to infer schema‐level structure necessary from information. The approach is illustrated using example geospatial land‐cover data. method then extended operate under uncertainty, such as in cases where data are inaccurate or imprecise. describes implementation software...
Abstract Real-time information about the spatial extents of evolving natural disasters, such as wildfire or flood perimeters, can assist both emergency responders and general public during an emergency. However, authoritative sources suffer from bottlenecks delays, while user-generated social media data usually lacks necessary structure trustworthiness for reliable automated processing. This paper describes evaluates technique real-time tracking perimeters based on publicly available...
Information about dynamic spatial fields, such as temperature, windspeed, or the concentration of gas pollutant in air, is important for many environmental applications.At same time, development geosensor networks (wirelessly communicating, sensor-enabled small computing devices, distributed throughout a geographic environment) present new opportunities monitoring fields much more detail than ever before.This paper presents model querying information using networks.In order to manage...
The present paper examines whether the formal topological characterisation of spatial relations between moving geographic regions provides an adequate basis for human conceptualisation motion events those regions. focuses on gradual changes in relationships caused by continuous transformations (specifically, translations). Using a series experiments, and perception conceptual neighborhoods is investigated. In particular, role characterising scrutinised. experiments employ grouping paradigm...
