Specific surveysSpecific surveys
1.1. Survey in municipal authoritiesSurvey in municipal authorities- - email correspondence with offices (email correspondence with offices (58 58 out out ofof7272 ((8181%) of towns and cities answered to my %) of towns and cities answered to my questionnaire)questionnaire)- - web pages of towns and citiesweb pages of towns and cities-- data from students work at our dempartmentdata from students work at our dempartment
2.2. Survey of GIS productsSurvey of GIS products- - web pages of firmsweb pages of firms- - conference reports concerning GISconference reports concerning GIS-- email correspondence with GISemail correspondence with GIS producersproducers
Complex IS vs. GISComplex IS vs. GIS
-- two two optionsoptions how to create GIS how to create GIS
a.a. create complex IS with GIS partcreate complex IS with GIS part(products T-WIST, Cityware,(products T-WIST, Cityware,
City2000)City2000)
b.b. create only GIS and try to cooperatecreate only GIS and try to cooperate withwith other IS, which is used in theother IS, which is used in the office office

ConclusionsConclusions
-- complex IS – best way, but it means complex IS – best way, but it means reconstruction of whole system (problem)reconstruction of whole system (problem)
-- platform GIS (better, more expensive, ideal forplatform GIS (better, more expensive, ideal forbigger cities)bigger cities)
-- independent solution (without analytical independent solution (without analytical functions, cheaper, ideal for smaller towns)functions, cheaper, ideal for smaller towns)
-- data storing – best way = RDBMSdata storing – best way = RDBMS-- interoperability (data formats) – problems with interoperability (data formats) – problems with
