Integration of Arctic Places with Multi-sources Data


Geographers describe the world more and more on the base of networks and flows. It is a matter of fact that one locality shows its development level through its connectivity to other localities, the national core and more largely the world-system. If this quality is low or missing, locality falls into the periphery. Therefore, within a regional or a city core, one can find pockets of periphery that seem left apart. Thus, the world is no longer organized by concentric circles from the core.The high latitudes is generally regarded as a periphery of the global system that experiences rapid and huge changes under two main drivers: globalization and climate change. Given its rapid evolution, it is difficult to represent emerging Arctic places and those that face decline.As cities and transport network have been intertwined throughout history, this research aims to picture the integration of Arctic localities. To do so, we examine transportation as well as social networks connecting Arctic settlements within the Arctic region and with the non-Arctic region. In this study, a sample of localities was extracted from Arcticapolis, a part of the French Research Group Geopolis dedicated to a geohistorical and worldwide settlement database. Arcticapolis targets all circumpolar countries. Selected localities are located within the Arctic limit created by the Canadian geographer Louis-Edmond Hamelin on the base of physical and human dimensions of the environment such as coldness, number of inhabitants...We look at the connection between settlements through four different networks using three different downloadable data for free on the web. First, for ground transportation, roads and railways, we use OpenStreetMap (OSM). Second, we consider for air routes, data from FlightRadar website which provides real-time flight schedules from 5,000 airports around the world. Third, as interactions between places can also be described by digital footprints, we explore connectivity through social networks using millions of geolocated data from Twitter.At the first step, such quantitative studies require appropriate and homogeneous datasets that are sometimes difficult to collect in a large region covering several countries. We examine the quality and the biases of each dataset especially within the study area (i.e. such as penetration rate for Twitter, users and quality assessment for OSM). Afterwards, we present different methods in graph creation from different sources and we propose a typology of the Arctic localities in terms of centrality.Finally, our study provides a picture of the Arctic places that allows us to question the common hypothesis “the closer to the north, the fewer integration”. It reveals sub-regions where settlements show stronger ties together than with others Arctic regions, as well as Arctic bridgeheads, connected directly with the outside of the circumpolar zone.
