Verification of data in GIS management system for state real estate
Latos, Dorota et al.
At present, GIS is being used in all fields of economic activity and administration. Its functionality combines spatial object, described by various attributes, with its location in geographical space. The superiority of GIS technology lies in its spatial, qualitative and quantitative ability, all in one and consistent with each other. Many people have recognized the value of GIS solutions, and used them on a daily basis. Therefore, the number of GIS users grows year by year. One of many possible applications of GIS is the management system for real estate. The authors of the paper work on a prototype of GIS management system for the Statees immovable (called the SZaNP System, for Police own real estate). This system requires combining data from many sources: local data that was used before the SZaNP implementation (i.e. MS Excell files), the Land Administration System data (i.e. the data concerning a parcel or a building, the owner and property rights) as well as the data concerning the costs of real estate management (in a form of indicative figures and values in relation to months and years). As it is commonly known the most important component of any GIS system is data. If quality of data (precision, completeness, timeliness) does not meet the requirements, there is high level of risk that the results given by the system will not be acceptable. Therefore in every GIS implementation data has to be cross-checked and carefully examined before and after loading to a data server. Verification of the data is especially crucial when data is gathered from many different origins of various formats.
