Oliver Roick GIScience. Research assistant.

I'm a research assistant at Chair of GIScience at Heidelberg University. My research activities are focused on Crowdsourced Geographic Information, especially quality, exploration and utilization of geo-spatial data from Location Based Social Networks.

Activities

Location Based Social Networks

My PhD focuses on the exploration and utilization of geodata from location based social networks. I'm especially concerned with quality aspects, data integration and the application within spatial data infrastructures.

OSMatrix

OSMatrix is a web based geovisual exploration application that visualizes information from the OpenStreetMap project, which is typically not shown on maps. It aims at providing tool to understand OpenStreetMap's user activity, topicality of data as well as number and types of mapped features in order to help identifying areas with unusual activities that might indicate spots with an increased need for quality control.

OpenRouteService

OpenRouteService is a web-based routing service which is entirely based on OpenStreetMap data and implemented using Open Source technologies and open standards. I am currently involved with the re-design and re-implementation of the client side components.
