Browsing the SFO Museum Aviation Collection Through Real Time Flight Data

We’ve created a map-based interface that shows real time (or more specifically real time -ish since there is a delay) flights as they are traveling to and from SFO, inside North America. For each of those flights we know the airline servicing the flight, and both its origin and destination airport. As a flight is updated we plot its location on a map and display a popup with a random object, for each facet, from the SFO Museum Aviation Collection. When you click on an object its dedicated web page on the collection.sfomuseum.org website will be opened in a new tab.

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.

Updating EXIF metadata in JavaScript (and WebAssembly)

One question that’s been raised about the camera/save button in zoomable images is whether or not the new image contains, or preserves, existing EXIF metadata information stored in the original file. The answer yesterday was: No. The answer today is: Not yet, but only because we haven’t enabled it and we will do that soon.
