Measuring the Reliability of Wheelchair User Route Planning based on Volunteered Geographic Information (OpenStreetMap)
The development of a wheelchair user friendly route planning application inherits a number of special requirements and details that need to be considered during the generation of the routing graph and the corresponding algorithm, making this task much more complex than car or pedestrian related applications. Each wheelchair type and, more importantly, each individual user…

Exploiting Big VGI to Improve Routing and Navigation Services
Due to development of communication technologies, the amount of data, which each organization has to deal with, has been rapidly growing. The huge volumes of data appear as an opportunity to improve the performance and reliability of various applications, as such routing and navigation services can be named. However, the analysis of large datasets, commonly…

Integrating and Generalising Volunteered Geographic Information
Our book chapter contribution in “Abstracting Geographic Information in a Data Rich World” has appeared. Abstract: The availability of spatial data on the web has greatly increased through the availability of user-generated community data and geosensor networks. The integration of such multi-source data is providing promising opportunities, as integrated information is richer than can be…

The emergence and evolution of OpenStreetMap: A cellular automata approach
Collaborative mapping projects, such as OpenStreetMap (OSM), have received tremendous amounts of contributed data from voluntary participants over time. So far, most research efforts deal with data quality issues, but the OSM evolution across space and over time has not been noted. Therefore, a new study is dedicated to the evolution of the contributed information…

Mapping land-use from OpenStreetMap
An approach toward generating land-use patterns from volunteered geographic information (VGI) without applying remote-sensing techniques and/or engaging official data has just been published in the latest issue of the International Journal of Geographic Information Science. Collaboratively collected OpenStreetMap (OSM) data sets are employed to map land-use patterns. Initially the spatial pattern of the landscape was…

Open Data Opportunities for LBS
The advent of web technologies and the promotion of data sharing practices have fostered open data initiatives. The main motivation of governments in sharing data with the public is to stimulate economic growth by enabling the creation of new products. One of the areas that could benefit from open data initiatives is that of location-based…

Call for Paper: Special Issue “GeoWeb 2.0” of the ISPRS International Journal of Geo-Information
The advancement of Internet technology is constantly changing the way geographic information is being collected, managed, processed, analyzed, and used. While a first wave of innovation has transformed Geographic Information Systems into Geographic Information Services, a second paradigm shift has recently been observed. This paradigm deals with crowdsourcing and the collaborative generation of geographic information.…
