Stage 1 – Geotagging for photographers
What we need:Digital Camera equipmentGPS TrackerSynchronisation toolsVisualisation (map services)
Geotagging & AR - Tony Fricko 5July 28th 2010
What ist Geo-Tagging ? For photographers: recording the exact position where a picture was taken With the aim to indicate the recording location on a map Or use this information with an increasing number of applications...

Metadata for digital photo objectsThere are multiple formats & standards for metadata
EXIF
Contains metadata describing the details from the camera equipment used to record the specific photo. It is defined by the Japan Electronic Industry Development Association (JEIDA) - Exif-specifications
IPTC (Core + Extensions) Another important set of standardized information is contained in the IPTC
headers of the International Press Telecommunications Council (IPTC) It is meant for use by professional photographers for cataloging and managing
large photo collections
XMP (Extensible Metadata Platform) Created by Adobe Systems for similar purpose as IPTC As a separate XML file it supports also RAW format
Vendor specific extensions Become more important, as some manufacturers start recording face recognition

Workflow – for batch processing
1. Record the GPS data (track)Datalogger extern or in camera *)
2. Synchronize time in camera and data logger
3. Take pictures (lots !)
4. Upload GPS data + photos to PC
5. Synchronise – insert GPS data into EXIF of photos
6. Display photos on maps or specific applications
*) steps 2,4,5 not required

GPS Receiver To collect geo location information there are
currently these device options for photographers:
1) integrated in cameraseveral consumer cameras emerging:e.g. Sony DSC-H5VX
2) dedicated data logger (Holux)
3) GPS logger dedicated for specific camerafor highend DSLRs (Solmeta, Dawntech)
4) Navigation systemstypical GPS tracking devices

How GPicSync works Synchronisation
GpicSync (an open source tool) http://code.google.com/p/gpicsync/
We take a track file ( .GPX ) and select a directory where the photos are located
Based on the time stamp, the program will attempt a 'best fit' assignment of coordinates into the Exif structure
Reverse Geo Tagging Optionally the GeoNames service can be used to
provide a human readable form of the location

Reverse Geo-Tagging GeoNames
A geographical database that contains more than 8 mill entries
Provides multiple web services interfaces (XML, JSON, etc) to search and convert coordinates into placenames
e.g. N 48° 18' 0''E 16° 21' 0'' into Langenzersdorf, Austria

Stage 2 – maps and layers - GeoWeb
So far we looked at geo-tagging photos and placed them on multiple map sources as featured objects
We now dive a bit deeper into how these geo-tagged objects are managed and what technology is used for mapping.
The big buildung blocks are: Base map + Geo-tagged objects (features) + Layering technology (for aggregation) + Browser for visualisation

Search for photos by location CDWinder – Media DB for Windows CDFinder – Media DB for Mac
Can search for photos within a predefined range ( xx miles ) http://www.cdfinder.de/de/de/de/geotagging.html
Useful e.g. when multiple visits to a city, e.g. Quito
Integration in GIS DB UK decided to open the maps of Ordonance Survey http://openspace.ordnancesurvey.co.uk/openspace/
And more personalized services: Face recognition + location combined !

Geotagging + compass in consumer cameraExample showing a photo from Sony DSC-HX5V on GeoSetter with OpenStreetMap
With integrated compass the camera orientation can be detected fairly precisely
Assisted GPS – satellite routes are pre-calculatedHelps for 'cold starts'

Wikipedia and related crowd sourcing efforts Wikipedia
Wiki Projects Geography WikiProject Geographical coordinates
Collection of a series of projects to correlate knowledge (articles) with a geo reference
One result is the offer of Web services to respond to queries like: Give me all articles in the vicinity of 0.5km given the
current location coordinates (long/lat) Wikipedia Geocoding Web Service

Outlook and business potential AR will provide multi million Dollar business on mobile
devices... Windsor Holden from Juniper Research predicts 730 mill Dlr
business for mobile advertising and marketing in the AR space by 2014 with 350 mill handsets enabled
Ice breakers will be location based searches on mobiles AR supported advertising
Odds: Unclear legal situation Device proliferation and lack of standards (may make the
development cost too high or create functional islands) 1st European AR conference: Berlin, April 2010 Mobile AR Summit 2010 @ MWC, Barcelona Feb 2010 ARE 2010, US June 2010

Summary – Consumer driven development based on geotagging Photography
Consumer cameras with increased functionality re geo-tagging More applications to exploit, incl. Face recognition and social network
apps Mapping
Data representation and analysis often easier to consume in geographical context
Geo-tagged material and freely available maps on the increase Mobile applications
The next big battle ground (search/find, marketing, games, social networks)
High-end device manufacturers and telecoms looking for killer apps and new revenue sources
Consumer driven by 'desirability' and convenience
