A Spatial Analysis of MoscowFuel Stations - GIS Lounge

Mapping Fuel Stations in MoscowUnderstanding The Impact of Fuel Stations in MoscowSpatial Location of Fuel Stations in MoscowEconomics of Fuel StationsEnvironmental Impacts of Fuel StationsThe Road/Traffic Safety AspectsAs input data the OpenStreetMap(OSM) and the Moscow Government OpenData were used. The OSM data contains not only geotargeted points but also has attributive data like the brand-name of the fuel-stations. It took a lot of manual work to add dozens of fuel stations and to verify their location (on foot, by car, through Yandex (the Russian search engine), Google StreetView, and with high resolution satellite images, etc). While I am not sure that the final map contains all fuel stations, the majority of them have been located and mapped. You can viewed the results of this project on the web GIS GeoMixer site. This web map is hosted by the Moscow State University Business School server: http://geo.mgubs.ru:8080/api/index.html?permalink=KA1Y4&A96WP. MSU BS is a leading business school in Russia where I taught the course, “Geographical Aspects of Business”. The “Fuel Stations” layer is presented on the “Social infrastructure Map of Moscow” which is actively used in the process of training.Get price
