What is it?What is it?• Application: human - machine

• Services: machine - machine

– Interoperability, distribute system

– Offering services, not data

– Data collection and management on one place, data are all time actualise

– Special black boxes on WEB as services

– Utilisation of different SW platforms

– User use only requested functionality

Our contributionOur contribution

• To build system on Mobile Internet platform,  • To use open platforms for building of this system.  • To define groups of users, describe the requested

functionality for defined groups of user and on the base of this functionality define user profiles.  

• To combine effective tools, which will offer information access, but also analytical tools, which will offer complex data analysis including 3D analysis 

Our contributionOur contribution

• To implement metadata model, this will be able to describe all available data source, including data validity, data history and data source.

• To offer possibilities of access to distributed data source and so increase effectively of data access and data analysis.  

• To build decision-supporting system

WMS applications developmentWMS applications development

• Under 5FP WirelessInfo IST-1999-21056 - The project aims to implement advanced wireless communications into multimedia systems and services for agriculture and forest administrations, business and NGO to improve access to agriculture and forest information. The communication via standard commercial equipment like as GPRS, GSM, HSCSD and special equipment developed for special cases are tested.

• Open source technologies are used
