To facilitate piloting the Green Comfort Index in Helsinki, a number of open geospatial data sources provided by the city are utilized. These are available from an open WFS API. Below, the data sets are briefly described with example query URLs used to retrieve them.
By combining the registries mentioned below, a following collection features depicting the green elements of the city is formed, with the data covering the entire administrative area:
The data offers a fairly detailed view to the cityscape:
For amenities such as city furniture, most of the data is maintained in the REGISTER OF PUBLIC AREAS IN THE CITY OF HELSINKI as 2D point features.
The register of public areas (YLRE) is a system of the Helsinki Urban Environment Division that contains information about the city’s street and green areas. The dataset is maintained for the use of the division and does not, as a rule, cover the assets in public areas that are the responsibility of the City of Helsinki’s other organisational departments or institutions. The information in the register of public areas is used to order maintenance for street and park areas in Helsinki. The information in the register is used, for example, in reporting on the activities of the Street and Park Department and in asset management of public areas.
