Nowadays indoor navigation and the understanding of indoor maps and floor plans are becoming increasingly important fields of research and application. This paper introduces clustering of floor plan areas of buildings according to different characteristics. These characteristics consist of computed human perception of space, namely isovist features. Based on the calculated isovist features of floorplans we can show the possible existence of greatly varying alternative routes inside and around buildings. These routes are archetypes, since they are products of archetypal analysis, a fuzzy clustering method that allows the identification of observations with extreme values. Besides archetypal routes in a building we derive floor plan area archetypes. This has the intention of gaining more knowledge on how parts of selected indoor environments are perceived by humans. Finally, our approach helps to find a connection between subjective human perceptions and defined functional spaces in indoor environments.

In this paper we propose a pipeline for highly automatic building reconstruction based on 3D point clouds. 3D building models are of great interest for many applications including city planning, navigation, emergency response and tourism and their reconstruction has been intensively studied. It is, however, still a challenge to minimize manual intervention and to achieve highly automated processing in practical applications. The main reason lies in the variability and complexity of urban scenes. We believe that one possible key to tackle this is a reliable primitive-based decomposition of urban scenes as well as their constituent buildings. It links scene interpretation with model reconstruction and, thus, naturally completes an automatic reconstruction pipeline. We propose an effective scheme for the decomposition of the whole scene straight into individual building components, i.e., primitives. The primitives are reconstructed via statistical generative modeling and assembled into individual watertight building models. An experiment has been performed on a dataset of a complete central European village demonstrating the potential of the proposed approach.

Many methods of indoor navigation for smartphones are augmented with Pedestrian Dead Reckoning (PDR) to improve accuracy and to reduce latency. PDR requires an accurate estimate of the device orientation. From the pitch and roll angles the sensor readings can be rotated to the horizontal plane, and with the yaw angle the direction of movement can be determined. While a simple implementation using only accelerometer and magnetometer is possible, more accurate results may be obtained by also including the gyroscope measurements. The approach in this paper uses a Kalman filter to fuse gyroscope with accelerometer and magnetometer readings. The system equation uses random walk on straight trajectories and additional gyroscope readings on turns. Turns are detected using a statistical test on the innovation of the Kalman filter as well as a condition on the estimated yaw-rate from the gyroscope. A second Kalman filter separates gravity from specific force by processing acceleration measurements. The estimated gravity is used in the orientation filter to determine pitch and roll. The filter has been tested using trajectories with known ground truth taken with off the shelf mobile devices in corridor and office environments. The outer heading accuracy approaches 10 degrees, dominated by systematic effects, largely due to magnetic disturbances. The achieved inner accuracy for the heading is 4 degrees.

A course named Seminar of Culture Studies is given to undergraduate students in the School of Cultural and Creative Studies of Aoyama Gakuin University in Tokyo, Japan, in which a new mobile application named Manpo was applied for the students to create location-based audio tour content in 2013, 2014 and 2015. With little background knowledge on geography and cartography, the students tried to draw maps and create georeferences for positioning on the maps using Manpo's functions. They also focused on recording audio guides for the POIs and walking routes, and bundled them to the maps together with photos and texts. The procedures of the classes and the students' performances were observed, in which the problems encountered by the students showed the difficulties, such as achieving appropriate georeferencing for accurate positioning, for non-professional users. However, the classes and students provided hints to the further development of Manpo, which also improved the classes and the students' works. As the course was proved to be a success, it inspired future research plans of a platform that can involve researchers, developers, mapmakers, local communities, and ordinary users to provide user-generated content including diverse maps for more attractive location-based services.

In this paper, we present the results of developing a geo-visual analytics application to support urban services. The goal is to allow non-GIS users to explore the taxi traveler's hot spots in Shanghai extracted from one week taxi floating car data (FCD). To achieve this, we proposed a workflow based on the visualization pipeline. Firstly, we preprocess the data to extract the origins (o) and destinations (d) from the FCD and apply data mining methods to detect taxi traveler's hot spots, to which semantics are further tagged using point of interest (POI) data extracted from OpenStreetMap (OSM) project. The detected hot spots are selected to show in the application for the user to conduct further visual analysis. Furthermore, we implement a web-based interactive visual explorative system, in which the graphic user interface contains multiple views (spatial, temporal and thematic) and interactive components are built up using the current web technologies. Finally, a possible use case of the application is introduced. Our results show that the developed geo-visual analytics application enables studying traveler's activity patterns. The visual analysis can be conducted with this tool for several aspects. The visual queries help to detect when and where hot spots occur and to compare the temporal distributions for nearby hot spots.

Distance measures, such as the Euclidean distance, network distance, and travel time, have been used in various urban models, such as models for transportation, land use, and human behavior. In this paper, we propose a novel distance measure based on the spatiotemporal distribution of residents, which is called the "Distance Measure based on Spatiotemporal Coexistence of Residents (DM_SCORE)". It is defined as the square root of the Jensen-Shannon Divergence, and can be calculated using person-trip survey data. We discuss the difference between the DM_SCORE and other distance measures, and apply it to urban models for the population density function, the spatial interaction model, and the spatial cluster analysis. The results of numerical analyses using actual data from Tokyo metropolitan area demonstrate that the DM_SCORE can be of great value in urban models.

Spatial similarity plays an important role in automated map generalization, spatial computations, spatial reasoning, spatial retrieval and the construction of multi-scale spatial databases. Nevertheless, the features of spatial similarity relations have never been investigated systematically, yet. To fill the gap, this paper focuses on quantitative expressions of the features of spatial similarity relations in map spaces. It firstly summarizes and analyzes the features of similarity in other fields, such as computer science, psychology and geography;then it proposes a number of features of spatial similarity relations in map spaces, i.e., equality, minimality, auto-similarity, symmetry (reflectivity), non-transitivity, triangle inequality, and scale dependency. Mathematical expressions of the features are presented and explained. Finally, potential research issues in spatial similarity relations are reviewed.

Daily mobility patterns in highly populated urban environments rely on a well-functioning effective road network. Nevertheless, traffic bottlenecks are typical for urban environments with periodic traffic congestion. In this paper, we focus on the investigation of how traffic congestion is related with complicated crossings. First, we select an approach for the classification of the complexity of road partitions and the derivation of complicated crossings based on geodata from OpenStreetMap (OSM). Second, we calculate traffic congestions using Floating Taxi Data (FTD) from Shanghai in 2007. Then, we develop a matching technique to link the congestion and complicated crossings, and subsequently define the concept of traffic bottlenecks represented by polygons. The bottlenecks indicate locations where the transportation infrastructure is complex and traffic congestion appears periodically. Finally, we select suitable cartographic representations of traffic bottlenecks in potential thematic vehicle traffic maps.

Efficient Computation of Bypass Areas

Route planning in road networks is a basic operation in the area of location-based services. Very often, the knowledge of the optimal route is not the only important information for a driver. Complex services could also present points of interest (e.g. hotels or gas stations) nearby the optimal route as stop-over. Here, 'nearby' means: the bypass route from a start to target that passes that point does not exceed certain costs. In this paper, we present an efficient approach to compute all bypasses that are within a given cost limit. We may additionally request only locally optimal bypasses, e. g., that reach an intermediate point without driving U-turns. The set of all bypasses called bypass area can be used for further queries, in e. g. geo databases to find nearby points of interest for a certain application or service. Our approach is fully implemented and evaluated and computes the respective bypass areas very runtime-efficient, whereas it re-uses similar structures as for optimal route planning.

Eye movements provide information on the mental processing of landmark objects while navigating. The present study investigates landmark-based navigation by pedestrians in real world environments using mobile eye tracking technology. The goal of the study is to identify whether landmarks on maps optimize the navigation procedure and the usage of a map, and imprint the cognitive map sustainably. Two independent test groups navigated through unfamiliar urban environment and were subsequently interviewed. One group had landmark visualized on a map as an additional aid, the control group did not. The results show that objects that are focused longer and more frequently transfer onto the mental map. Upon recalling objects present in the surroundings, on average 8.3 landmarks were named per interview by the landmark group, compared to 7.0 for the control group. For the control group, the usage and duration of observation of the map was thereby approximately 1.7 times greater than for the landmark group. Following the memory test, the participants in the landmark group remembered significantly more objects and located these correctly as compared to the control group. In summary, the results show that the visualization of landmarks on maps optimizes the use of maps for navigation, whereby more landmark objects transfer to long-term memory and the mental map.
