We made last Friday this visualisation:
It represent the powerindex on the hitch resistance of the Fleuren tractor combined with the GPS coordinates. This picture is zoomable. We used Spotfire from Tibco for this.
With this tool you can make pre-defined models which you can connect directly to a database. You can provide a URL to the user, who will be able to address the model through a web browser.
Advantages for this approach are that the user has allways “up to date” information, cann’t fake the data and iseasy to use without hours of adjusting Excel an CSV files.
