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.
  • Select a feature to read its name and source fields. Use the source link to inspect the original record.
  • The OpenStreetMap snapshot date is 2026-09-14T23:04:21Z. The dataset was prepared on 15 September 2026.
  • Only observatories explicitly tagged as astronomical are included. Weather stations and sites without the astronomical type tag are absent. Public visits are not confirmed.
  • 4 source records were omitted by the subject, geometry, and duplicate checks described here.
