In MetropAccess research group we have produced GIS datasets concerning accessibility issues in Helsinki Metropolitan region. We have calculated travel times and distances from all FEI (Finnish Environment Institute) YKR-grid cells to all YKR grid cells (n = 13230) by walking, public transportion and car.

MetropAccess research group will organize an accessibility-related workshop in 14.2.2014. Event will be held in Physicum building in the campus of Kumpula (Gustaf Hällströmin katu 2).
In the workshop we will demonstrate analytical tools that we have developed for analysing accessibility by different travel modes in Helsinki metropolitan region.
More information and registration can be found here. (in finnish only).
Katumetro research programme granted us continuation for our funding. Our work continues!

Here, we tested different accessibility measures in land use / land cover change models in Amazonia. Proper time distance surfaces are most useful when doing modelling the deforestation patterns of the Peruvian Amazonia. However, also combinations of Euclidean distance surfaces (Euclidean distance from the cities and from the rivers) perform fairly well at least in our study area.

The 5th Nordic Geographers Meeting was held in Reykjavík, Iceland, 11 – 14 June 2013. MetropAccess participated in the “Responsible Mobilities” session with a presentation that was done in collaboration with the Everyday Urbanity -project (Aalto University). We also had our poster in the poster session.
MetropAccess got again funding from the Helsinki Metropolitan Region Urban Research Program – new research topics during the new year!
