The orthophotos were taken at 20 cm/pix terrain resolution in the summertime, and the regional coverage of the materials varies slightly from year to year. Data is currently provided only via HSY's interfaces as a colour orthophoto mosaic (RGB image). When necessary, you can inquire about false-colour photos at email@example.com. The data is in the ETRS-GK25 coordinate system. The data have been implemented as a joint procurement and the party responsible for the procurement was the Helsinki Region Environmental Services Authority (HSY) municipal federation.
