Vantaa's orthophotographs from different years are available through the WMS interface. An orthophoto is an aerial map of the entire area of Vantaa. An orthophotograph is an aerial mosaic of aerial photographs corrected to a map projection, showing the ground surface as seen perpendicularly from the air and corrected for a plane map.
In addition, false colour images of Vantaa are available for the years 2011, 2015, 2019 and 2021. A false colour image is also a georeferenced image (it can be used as a map), but it differs in colour from other orthophotographs. In the false-colour image, vegetation appears red and inanimate surface appears grey/bluish depending on the colour adjustments. The false-colour images can be used to identify tree species and stand condition and are used in forest management planning.
The resolution of a published orthophotograph, i.e. the size of a single pixel, is about 20 cm in the landscape, depending on the year of the image.
