Point Labeling with Sliding Labels in Interactive Maps 17

Point Labeling with Sliding Labels in Interactive Maps

17th AGILE Conference on Geographic Information Science

We consider the problem of labeling point objects in interactive maps where the user can pan and zoom continuously. We allow labels to slide along the point they label. We assume that each point comes with a priority;the higher the priority the more important it is to label the point. Given a dynamic scenario with user interactions, our objective is to maintain an occlusion-free labeling such that, on average over time, the sum of the priorities of the labeled points is maximized. Even the static version of the problem is known to be NP-hard. We present an efficient and effective heuristic that labels points with sliding labels in real time. Our heuristic proceeds incrementally;it tries to insert one label at a time, possibly pushing away labels that have already been placed. To quickly predict which labels have to be pushed away, we use a geometric data structure that partitions screen space. With this data structure we were able to double the frame rate when rendering maps with many labels.

Current positioning and sensing technologies enable the collection of very large spatio-temporal data sets. When analysing movement data, researchers often resort to clustering techniques to extract useful patterns from these data. Density-based clustering algorithms, although being very adequate to the analysis of this type of data, can be very inefficient when analysing huge amounts of data. The Shared Nearest Neighbour (SNN) algorithm presents low efficiency when dealing with high quantities of data due to its complexity evaluated in the worst case by O(n(2)). This chapter presents a clustering method, based on the SNN algorithm that significantly reduces the processing time by segmenting the spatial dimension of the data into a set of cells, and by minimizing the number of cells that have to be visited while searching for the k-nearest neighbours of each vector. The obtained results show an expressive reduction of the time needed to find the k-nearest neighbours and to compute the clusters, while producing results that are equal to those produced by the original SNN algorithm. Experimental results obtained with three different data sets (2D and 3D), one synthetic and two real, show that the proposed method enables the analysis of much larger data sets within reasonable amount of time.

Due to the dynamic nature and heterogeneity of Volunteered Geographic Information (VGI) datasets a crucial question isu concerned with geographic data quality. Among others, one of the main quality categories addresses data completeness. Most of the previous work tackles this question by comparing VGI datasets to external reference datasets. Although such comparisons give valuable insights, questions about the quality of the external dataset and syntactic as well as semantic differences arise. This work proposes a novel approach for internal estimation of regional data completeness of VGI datasets by analyzing the changes in community activity over time periods. It builds on empirical evidence that completeness of selected feature classes in distinct geographical regions may only be achieved when community activity in the selected region runs through a well-defined sequence of activity stages beginning at the start stage, continuing with some years of growth and finally reaching saturation. For the retrospective calculation of activity stages, the annual shares of new features in combination with empirically founded heuristic rules for stage transitions are used. As a proof-of-concept the approach is applied to the OpenStreetMap History dataset by analyzing activity stages for 12 representative metropolitan areas. Results give empirical evidence that reaching the saturation stage is an adequate indication for a certain degree of data completeness in the selected regions. Results also show similarities and differences of community activity in the different cities, revealing that community activity stages follow similar rules but with significant temporal variances.

With the advent of Volunteered Geographic Information (VGI) the amount and accessibility of the spatial information such as sketched information produced by layperson increased drastically. In many geo-spatial applications, sketch maps are considered an intuitive user interaction modality. In sketch maps, the spatial objects and their relationships enable users to communicate and reason about their actions in the physical environment. The information people draw in sketch maps are distorted, schematized, and incomplete. Thus, processing spatial information from sketch maps and making it available in information systems requires suitable representation and alignment approaches. As typically only qualitative relations are preserved in sketch maps, performing alignment and matching with geo-referenced maps on qualitative level has been suggested. In this study, we analyzed different qualitative representations and proposed a set of plausible representations to formalize the topology and orientation information of extended objects in sketch maps. Using the proposed representations, the qualitative relations among depicted objects are extracted in the form of Qualitative Constraint Networks (QCNs). Next, the obtained QCNs from the sketch maps are compared with QCN derived from the metric maps to determine the degree to which the information is identical. If the representations are suitable, the QCNs of both maps should be identical to a high degree. The consistency of obtaining QCNs allows the alignment and integration of spatial information from sketch maps into Geographic Information Systems (GISs).

Location-based applications require knowing the user position constantly in order to find out and provide information about user's context. They use GPS signals to locate users, but unfortunately GPS location systems do not work in indoor environments. Therefore, there is a need of new methods that calculate the location of users in indoor environments using smartphone sensors. There are studies that propose indoor positioning systems but, as far as we know, they neither run on Android devices, nor can work in real environments. The goal of this chapter is to address that problem by presenting two methods that estimate the user position through a smartphone. The first method is based on euclidean distance and use Received Signal Strength (RSS) from WLAN Acces Points present in buildings. The second method uses sensor fusion to combine raw data of accelerometer and magnetometer inertial sensors. An Android prototype that implements both methods has been created and used to test both methods. The conclusions of the test are that RSS technique works efficiently in smartphones and achieves to estimate the position of users well enough to be used in real applications. On the contrary, the test results show that sensor fusion technique can be discarded due to bias errors and low frequency readings from accelerometers sensor.

This chapter presents an original approach to anomalous behavior analysis in trajectory data by means of a recursive Bayesian filter. The anomalous pattern detection is of great interest in the areas of navigation, driver assistant system, surveillance and emergency management. In this work we focus on the GPS trajectories finding where the driver is encountering navigation problems, i.e., taking a wrong turn, performing a detour or tending to lose his way. To extract the related features, i.e., turns and their density, degree of detour and route repetition, a long-term perspective is required to observe data sequences instead of individual data points. We therefore employ high-order Markov chain to remodel the trajectory integrating these long-term features. A recursive Bayesian filter is conducted to process the Markov model and deliver an optimal probability distribution of the potential anomalous driving behaviors dynamically over time. The proposed filter performs unsupervised detection in single trajectory with solely the local features. No training process is required to characterize the anomalous behaviors. Based on the results of individual trajectories collective behaviors can be analyzed as well to indicate some traffic issues, e.g., turn restriction, blind alley, temporary road-block, etc. Experiments are performed on the trajectory data in urban areas demonstrating the potential of this approach.

Sketch maps of routes have been widely used to externalize human spatial knowledge and to study wayfinding behavior. However, specific studies on what information and how people recall route information they obtain from verbal instructions by drawing sketch maps are limited. This chapter aims to know how much information, especially landmarks and streets, people recall after following a wayfinding task. We conducted an experiment and asked participants to draw a sketch map of the route they travelled. Landmarks were classified based on their locations on the route. Sketch maps were compared with verbal instructions to analyze what specific landmarks and street information people recalled as well as what other information was added. Our study showed that (1) landmarks along the route were sketched as often as landmarks located at decision points;(2) participants added landmarks and streets which were not mentioned in the verbal instructions. This chapter provides a better understanding of wayfinding strategies and spatial learning.
