It includes about 40,000 photographic objects. The photos predominantly show points in the national triangulation network. This sub-collection also documents how people used to work. It thus tells the story of the adventurous life of national topographers.","summaries":{},"extent":{"spatial":{"bbox":[[5.965547342033351,45.82438672559895,10.505171278866573,47.79369428211846]]},"temporal":{"interval":[["1000-01-01T00:00:00Z","2024-09-25T00:00:00Z"]]}},"license":"proprietary","created":"2025-07-17T13:59:45.006470Z","updated":"2025-12-15T21:00:24.277397Z","links":[{"rel":"self","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.swisstopo.technische-aufnahmen"},{"rel":"root","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"parent","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"items","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.swisstopo.technische-aufnahmen/items"},{"rel":"alternate","title":"STAC Browser","type":"text/html","href":"https://data.geo.admin.ch/browser/index.html#/collections/ch.swisstopo.technische-aufnahmen"}],"crs":["http://www.opengis.net/def/crs/OGC/1.3/CRS84"],"itemType":"Feature","assets":{"technische-aufnahmen_metadata_tna.csv":{"title":"TNA Technische Aufnahmen","type":"text/csv","href":"https://data.geo.admin.ch/ch.swisstopo.technische-aufnahmen/technische-aufnahmen_metadata_tna.csv","created":"2025-09-09T09:24:25.300980Z","updated":"2025-09-09T10:05:55.363598Z","checksum:multihash":"1220d7242b1bfcb80f4b7696e6ca63c0cee3da2dc1f4573190a46c3d4a19096b498b"},"technische-aufnahmen_metadata_instr.csv":{"title":"INSTR Instrumentensammlung","type":"text/csv","href":"https://data.geo.admin.ch/ch.swisstopo.technische-aufnahmen/technische-aufnahmen_metadata_instr.csv","created":"2025-09-09T09:24:31.010415Z","updated":"2025-09-09T09:24:33.092356Z","checksum:multihash":"1220c17cf34cd08857f29ab9d64d3ef80e7cd1d14d5335561535ee66690e34c6b752"}}}
