Hi! I attended the workshop on OpenHistoricalMap at the SOTM in Heidelberg and talked with Sanjay afterwards. It's a very interesting project!
I noticed you already have an Overpass API for OpenHistoricalMap - but according to the Wiki, you can't use it with Overpass Turbo. This is not true, you can enter the OHM Overpass URL into Overpass Turbo settings. I documented this here: https://wiki.openstreetmap.org/wiki/Open_Historical_Map#Using_the_data Also, we talked about dates. The start_date (and the end_date which you want to use) have a very complex syntax. For my project OpenStreetBrowser I've already written a parser and a human readable formatter (as npm modules): - https://github.com/plepe/openstreetmap-date-parser - https://github.com/plepe/openstreetmap-date-format I had the idea, that we also need a regular expression generator - so you can search in Overpass for objects matching certain criteria (like: give me all objects which were built in the 17th century or before/after a specific date). Here you are: - https://github.com/plepe/openstreetmap-date-query I'm also planning to integrate this into OpenStreetBrowser - this could be useful in the category "Buildings age", where you could filter for buildings from a certain date range: https://www.openstreetbrowser.org/#map=18/47.07108/15.43863&categories=buildings-start_date Hope this is useful for the OpenHistoricalMap as well! I'm looking forward to contributions (e.g. additional translations for the date formatter). greetings, Stephan -- Seid unbequem, seid Sand, nicht Öl im Getriebe der Welt! - Günther Eich ,----------------------------------------------------------------------. | Stephan Bösch-Plepelits ❤ code ❤ urbanism ❤ free software ❤ cycling | | Projects: | | > OpenStreetMap: openstreetbrowser.org > openstreetmap.at | | > Urbanism: Radlobby Wien | | Contact: | | > Mail: [email protected] > Blog: plepe.at > Code: github.com/plepe | | > Twitter: twitter.com/plepe > Jabber: [email protected] | | > Mastodon: @[email protected] | `----------------------------------------------------------------------'
