GIS software (Geographic Information Software) are very used nowdays especially througt the Internet and its public access, with software as Google Earth or Mappy for example.

The Valencian spain company Prodevelop is a partner of the company Iver which created of the open source Java project gvSIG (software GIS for PC). Prodevelop is a contributor of gvSIG and also in charge of the development of a mobile extension to gvSIG, named gvSIG Mobile.

As you know, OpenMobileIS is especially providing mobile solutions for IS (Information System).
That’s why, the combinaison between the both technologies (link GIS and IS services on mobile tool) are today a strong objective and challenge for the OpenMIS team. It will permit to have a real great interaction bewteen the two type of software and combine their power.

The project which uses OpenMIS and gvSIGMobile is named Tellus, reference to the goddess of Earth in Roman mythology.
Tellus has got three main ways of development :
- A real mecanism of map synchronisation based on the OpenMobileIS synchronisation engine to resolve the differents types of conflicts which could appends. And an optimisation of networks transfers based on the BitTorrent protocol.
- Providing a framework of development to allow interactions and communications between gvSIGMobile and an OpenMIS mobile application.
- Offering a real security for the datas GIS and IS during the synchronisation process and on the mobile tool.

Tellus is today in a R&D phase, and will be terminated (at least for the main points) for this summer (2009)
