The distances in the database sometimes seem off. What’s happening here?
The database works with linear (airline) distances. They can differ quite considerably from the distance you would actually have to drive to get there. We have opted for using linear distances in the database because selecting the ten closest filling stations based on road kilometres would be much more complicated. Theoretically, it would be possible.
Also, the database calculates the distance from the geographical centre of the unit you have used as search criteria, i.e. the street, district or postcode area. For instance, the distance in the database between two towns is calculated centre to centre – while street signs usually refer to distances between area boundaries.
