With the test we had done before, we now have a better understanding on how to perform city-wide measurements. Yesterday, we performed our second run measuring a large part of Turku in detail. The results are not as surprising as from our first city-wide test, but still interesting. As expected most of Turku is very clean, and the usual areas with more traffic show up as having pollution. Turku, and other cities, use three different levels of administrative divisions, from more granular to more detailed. Our business model will be based in part on this granularity in our reports, the more detail is needed the higher the costs and thus the higher the price.
The view below show wards (suuralueet) which are the largest division, districts (alueet) and the smallest division into areas (pienalueet). Interestingly, boundaries of these areas and districts do, however, not always overlap.
As can be seen from the views above, the larger the reporting area the more data is being averaged and some of the detail is lost. The views below illustrate further the type of detail we can provide, which could even be more detailed if we take more time to measure certain areas. The area summary is more easy to read but the other view reveals where the pollution is actually located. While both have their uses, the more detailed view is far more interesting as it can potentially reveal pollution in specific streets of an area.
