8 INTERACTIVE WELL- BEING WEBMAP PROJECT CITY OF TURKU FINLAND 5th EC-GIS Workshop, "GIS OF TOMORROW" Stresa, Italy, 28 - 30 June 1999 Jukka Nikulainen / 29.6.1999 Coordinate based mapping Summary presentation method All information is positioned into a matrix of pixels or cells (500 x 500 m, 1000 x 1000 m etc.) Neighbourhood analysis = The value of a pixel is depending on the number of cases and inhabitants in the pixel and surroundings The variable size sample areas have the same amount of population or expected value Sample areas

11 INTERACTIVE WELL- BEING WEBMAP PROJECT CITY OF TURKU FINLAND 5th EC-GIS Workshop, "GIS OF TOMORROW" Stresa, Italy, 28 - 30 June 1999 Jukka Nikulainen / 29.6.1999 Coordinate based mapping Advantages: Data Security in acceptable level Privacy protection in acceptable level ? Controlled statistical behaviour Identification of phenomena Disadvantages: Requires a good (spatial) standard of databases Random effects are possible The map is only a reflection of (possible) phenomena, not a presentation based on true values

12 INTERACTIVE WELL- BEING WEBMAP PROJECT CITY OF TURKU FINLAND 5th EC-GIS Workshop, "GIS OF TOMORROW" Stresa, Italy, 28 - 30 June 1999 Jukka Nikulainen / 29.6.1999 Conclusions Separated services for the Intranet and Internet (+ Extranet) users Access control does not guarantee privacy protection and data security On-line access to the databases is an excluded option All personal information must be removed from the databases used in the service The conversion procedure (linking together geometrical and attribute data and removing personal data) must be separated from the service Legal and ethical issues must be studied carefully NO MISTAKES!! Thank You!! GIS & Internet technology:
