Geotagging at SFO Museum: Client-side EXIF, Web Components, Tilepacks, AppRunner and Live Demos
While this particular instantiation of the geotagging application is scoped to the physical boundaries of SFO the code itself is not specific to SFO Museum. It can be used, in combination with custom databases of map tiles and geographic data, with any image on your computer. This code will continue to be the common infrastructure that we build a SFO Museum application, specific to our needs, on top of.

Geotagging at SFO Museum: Protomaps, search and reverse-geocoding
The bad news is that, when you look closely, there really are that many moving pieces when it comes to something like geotagging photos. The good news is that nearly all of those moving pieces, from the underlying data to the tools to operate on those data, are within the reach of cultural heritage as low-cost and open-source alternatives to the commercial offerings. We may still need to stitch those pieces together to meet the needs of a specific institution but at least they are within reach now.

Updating (and reverse-geocoding) GPS EXIF metadata
When I save an image of this view of the runways at SFO, from 2017, the newly created image’s EXIF data contains not only the date and the permanent URL for the map but also the latitude and longitude coordinates for the map’s center point.
Reverse-Geocoding in Time at SFO Museum
Have you ever wanted to be able to reverse-geocode a point not just in space but also in time? Have you ever wanted to do that date-filtering with fuzzy or imprecise dates, encoded using the Extended DateTime Format (EDTF) ? Have you ever wanted to do both of these things with an arbitrary subset of location records? Have you ever wanted to be able expose these things as a web application and an API that doesn’t need to talk to a remote database? Have you ever wanted to be able to deploy those applications both locally and as serverless applications running on a cloud-provider’s infrastructure? Now you can.
