Model of Quality of Cadastral Map
2010
Anita Jansone, Velta Parsova

Cadastral map in modern market economy in different fields is marketable product. Summarized on it digital geospatial data, obtained in cadastral survey, can be widely used by many users. These data are captured using different methods of cadastral surveying therefore they have different accuracy. Land parcel boundaries are updated in compliance with data of higher accuracy. Wherewith, assessment and improvement of quality of cadastral map is very actual. Therefore is necessary to qualify level of quality of cadastral map data in order to meet particular customers particular requirements. The aim of research is to define model of quality of cadastral map, as well as to assess its application for assessment of quality of cadastral map. Therefore is necessary to evaluate compliance of cadastral map to customer’s requirements and particular purpose of use. Unlike textual data for assessment of quality of geographical information international standards are developed. In the research international standard of geographical information ISO 19113 is particularly analysed, where are defined main principles of quality. Producers and users point of view can be harmonized if their requirements are similar or analogous. Since 2005 State Land Service works on development of model of quality for assessment of cadastral map quality. Investigating tasks and objectives of use of cadastral map, in the research are proposed parameters of quality of cadastral map. These parameters are obtained on the estimation of experts. On the basis of proposed parameters of quality, in order of purpose of use were determined 9 parameters of quality of cadastral map. Most precise co-ordinates on cadastral map and most arranged textual data have objects of cadastral survey, therefore of quality of cadastral map depends of amount of cadastral survey in Latvia.
