Surface elements mapped by photo-interpretation - MEL

Surface objects present on the territory of the European Metropolis of Lille. Data is produced by the Data and Geographic Information Directorate

==> based on the topographic surveys** of the surveyors of the MEL on the road part,

==> and by photo-interpretation thanks to the orthophotographs available in-house.
