Concentrating to jobs

Our fourth GIS practical was about clusters of different activities in cities and creating heatmaps to visualize them. I did this as a pair work with my colleague Lauri Ovaska. We analysed the employment clusters inside the Helsinki Capital Area (cities of Helsinki, Vantaa, Espoo and Kauniainen) by using the grid data of Finnish Environment Institute SYKE covering employments around the area in 2010. Our target employment fields were the

Getting more serious: what the heck is Haaga about?

During the last weeks of our studio course, we have been taking some insights to the suburb of Haaga. We have been reconstructing its pre-urban environment, studying its development during the 20th and 21st centuries, thinking about its densities and diversities, and so on. Now we are at the point to make some real research and research questions about Haaga. The most interesting feature for myself, when discussing about Haaga,

Magical mix – of people

In the tradition of social sciences, the diversity of people has been a very essential part of research and studies. Researches, teachers, students and just normal people are more and more aware of the existing human diversity, when it comes, for example, to ethnicity, skin colour, abilities, religion, gender and sexual orientation. When they exist in world on the global and national level, they do exist too in urban environments.

Urban Soundscape

During our urban excursion in September, we didn’t just cycle around and observe the visual urban landscape. We also used our ears to listen the auditive atmosphere in Helsinki’s suburbs. Together with my student colleague Tuomas Tavi, we recorded some short clips along our excursion route and compiled them into a 36-second soundscape. Our soundscape includes seven different clips from different urban environments. The first three of them were recorded

Beyond Wikipedia, along the track

This week our studio work focused on the urban transition of Haaga. Each of us selected one source document to take a look in Haaga’s growth since the late 19th century. My personal perspective is the rail transportation: how the Helsinki­–Turku railway, opened in 1903, and the later commuter railway to Vantaa since 1975, have effected and co-existed with the growing suburb of Haaga. My actual source is the Finnish

Reconstructing Haaga

Urban environment – natural environment. Are they opposites to each other, and what is the difference? What is urban nature? What are ecosystem services? These themes were discussed during our second week of USP studies under the topic of “DNA, nature and cities”. It combined several aspects from environmental sciences, philosophical studies, urban economics and anthropology. In our first Urban Studio course, we are concentrating on Helsinki’s northern sub-centre Haaga.

GIS: Getting Into the Surface

Our first GIS and visualization practical handled the green areas in Helsinki’s small areas and the population pressure on them. We used the three data files: Helsinki land cover data 2012 (raster data), which included only the green areas of Helsinki, Helsinki’s population grid 2017 (vector data), and the Helsinki municipality borders and small areas (vector data). Green areas I began with the small areas data and calculated the area

First things first: Excursion

On September 12th and 13th, our USP group started the semester by bicycle excursion throw different suburbs and housing areas in Helsinki and Espoo. The almost 20-kilometre axis from Myllypuro to Leppävaara via Viikki, Käpylä, Haaga and Pitäjänmäki drawed the diverse layers and corners of Helsinki’s metropolitan cityscape. With our multiple backgrounds and perspectives, we collaborated a great perception towards the metropolis by also getting to know our new home
