This project is inspired by OldSF.org.
Disclaimer: We are not affiliated with Amsterdam City Archives/beeldbank
The source of the images is Amsterdam City Archives/beeldbank.
We used public API provided by that service to aggregate collection of photos and geocoded each photo to put them on Google Maps.
We have ~ 1/5 of the content available on the web site and are working on improving geocoding mechanism to put another part for areas like Amstelveen and others.
@viatsko & @fedosikhina created it during weekend trips in Netherlands.
If you want to know more, we've recently published the whole process on Medium OldAms.nl — the process of creating the largest collection of historical photos of Amsterdam on map.
Also, the source code is available on GitHub.
