About

GeoTracing is a software platform for creating multimedial geo-applications. These applications have in common that they allow you to tell your multimedial story about your movement through the landscape, whether on foot, skates, by bike or other means. View for example the TraceLand application. You can there sign up and download the MobiTracer mobile client.

Applications

The following applications have been or are being developed with GeoTracing. The main line of development is now (2008) done within the 7scenes platform.

Traceland	GeoSkating	N8Spel
Bliin	Mobile Learning Game Kit	GeoSailing
SenseOfTheCity	SenseOfBrainport	OtterTracing
GeoBiking	Digital Dowsing Rod

Concept

The main concept is depicted above. The MobiTracer is a personalized Java (J2ME) application running on a mobile phone. MobiTracer reads GPS location data from a Bluetooth GPS module and sends it to a server. Within a browser the routes followed by MobiTracers can be viewed. Each MobiTracer can also be followed in real-time moving over the map. In addition the MobiTracer can send track-annotations in the form of media (images/video/audio/text) ratings (e.g. road-conditions). to the server. Annotations are shown at their geographic locations on the map. The server stores all data in a Content Management System (CMS) such that it is available to a wealth of applications like map-creation, geodrawing, playing back routes, geo/mobile-gaming etc.

Through the WebEditor personal tracks can also be managed. For example, you may have a handheld GPS (say a Garmin) that logs tracks for you. You may export those tracks to GPX and upload them to the server. Be sure to add timestamping info. In addition you may submit e.g photo's taken with a digital camera. Through the photo's timestamp these get geo-tagged to their locations (or you may point-and-click). Tracks created through the MobiTracer may be edited and annotated.

The server stores tracks in a Content Management System no matter how they were created.

Features

• record GPS tracklogs remotely from mobile phone
• create GPS tracklogs remotely by (GPX) upload
• submit and relate media (audio/video/images/text) to points in GPS tracklogs
• annotate tracklogs with route parameters (e.g asphalt rating, sceneray rating)
• create overlayed maps by combining tracklogs
• live/real-time tracing in browser
• view and play back tracks in browser
• Location Based Services (LBS) through trigger on geotagged objects (e.g. media)
• portal functions: personal tracklogs and media
• tagging: give tags to any items (tracks, media persons)
• commenting: provide comments on any item (tracks, media persons)
• extensibility: server-side plug-ins
• open/XML-based protocols: create clients in any technology

Technologies

KeyWorx is the underlying technology for GeoTracing. KeyWorx is developed by Waag Society. Other technologies used are Pushlets (for real-time browser events), AJAX and Google Maps.

Development

GeoTracing is in the process of going Open Source. Thanks to the folks at CodeHaus we have a space at geotracing.codehaus.org

Documentation

Documentation is maintained in the GeoTracing Wiki. This will in the coming time moved to geotracing.codehaus.org.
