Photospace is an open platform for searching, viewing and annotating digital media in time and space.

For example, Saturday, Feb 5, 2005

  • web search
  • rss reader
  • tiger map
  • rdfmapper
  • create new rdfmapper map with rss & sf map
  • follow date and location references
  • search by zip


Photospace is plumbing.

Everything is a search.

Simple concept - index digital photo information and make it available through powerful searching to as many uses and contexts as possible.

  • It's an onion
  • The same core libraries drive the command line client as the web searching interface

How You Use It

  1. Take a whole mess of digital photos and put them in a folder
  2. Optionally, geotag the photos
  3. Download and install the Photospace web application
  4. Point Photospace at your photos
  5. Browse/search the Photospace web interface, and/or
  6. Write your own client application

  • Folder-based organization is important for low effort - local directory, ftp, scp, LAN, WebDAV
  • Web application provides edit, rotate, delete

Geotagging Digital Photos

GPS not required.

Software for EXIF editing:

Options for geotagging:
  • Use a GPS
  • Location stamp by hand
  • Edit metadata in photospace
  • Ricoh Pro G3 GPS Camera, cameraphone
The easiest is GPS - best on a hike or day tour. For one or two photos it is not great.
  • WWMX Location Stamper (Windows)
  • GPS PhotoLinker (OSX):

So What

Looking for narrative
What implicit metadata is in digital media and how can we use it to find meaning and narrative?

Sharing and using metadata
How can metadata be shared among systems to find more meaning and tell better stories?

What are maps for? Other ways to use location information?

  • Tell quokka history, first ascent v marathon des sables
  • RDF/RSS is emerging as lingua franca for system integration
  • Tags are even lower common denominator
  • Maps have turned out to be more of a puzzle than I expected
  • I find myself asking, so what?
  • Things on a map are an intermediate step in navigating an association
  • What's nearby v. where is it - similar to same time v. what day
  • Precision enables interesting things - Amazon A9, composite images, represenations of space
