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.

Geotagging at SFO Museum, Part 8 – Old maps
What’s become clear as we work through geotagging photos in the SFO Museum collection is that it’s very useful to be able to geotag things using a map from, or near to, the same year that a photo was taken. The facts on the ground change often and fast enough at SFO that it can be hard to make sense of an old photo using a contemporary map.

Geotagging at SFO Museum, part 2 – First Steps
In the end we may deploy this application for staff as a hosted website on the internet but we would like to have the ability and the flexibility for staff to also run the application locally, from their desktop. The majority of museum staff are not developers and won’t know how or be able, or want, to install the external dependencies that might be necessary for an application written in another programming language to run.

Map updates, 2019 - 2020
We’ve updated the historical aerial maps section of the Mills Field website to include imagery from 2019. We’ve also made some user interface and user experience changes to the map to improve its use on small and mobile sized devices.

More recent old maps (and the shapes in the details)
Wandering around the airport at high zoom levels, seeing the “shape” of airport in its details, is so much fun we’ve added a handy 📷 button to the map that will allow you to create an image of whatever you happen to be looking at.

Sweet spots between the extremes
This is a technical blog post about map tiles, caching, third-party services, so-called “serverless” computing and sustainability. It’s also about improvements to open-source software for managing all of that stuff.

More old maps and more-better architectures
All of these many SFOs are important because they help to contextualize things (like the photo of Rotunda A) in the moment but also to demonstrate how that context has changed over the years.

Who’s On First at SFO Museum
Today, we are happy to announce the first release of historical building footprints and interior spaces, including galleries and public art, at the San Francisco International Airport (SFO) as an openly licensed dataset. The data spans the years 1954 through 2018 and is published under the Linux Foundation’s Community Data License Agreement - Permissive 1.0 (CDLA).

Old maps (and old map tiles) at SFO Museum
Did you notice the aerial overlay of the airport in final image in our last blog post about maps? That’s what this blog post is about.

Maps (and map tiles) at SFO Museum
Maybe these maps are simply a fail-safe and only used when nothing else works. Their value then comes from giving us the confidence to try a more sophisticated approach while still having a way to get home safely, so to speak.
