Our 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 

9
Our 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 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

11
WirelessInfo results

• Mobile Internet GIS applications (multimodal,
  multiterminal) for field computers, PDA, MDA, WAP
  (WBMP format) communication human-computer,
  computer-computer machine-computer
• WMS, WFS mobile services
• Mobile data management
• Web coordinate transformation services
• Location Based Services (LBS)
• GIS analysis services
