About this dataset

This map contains 691 mapped records for World astronomical observatories. OpenStreetMap coverage depends on local contributors.
The map includes observatories that the source explicitly classifies as astronomical. Observatory records without that classification are excluded. Area and line records use their mapped bounding-box centre. A centre can be outside an irregular shape and does not mark an entrance.
