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 actually. 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 the main principles of quality are defined. 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. Pētījumā sīkāk analizēts Ģeogrāfiskās informācijas starptautiskais standarts ISO 19113, kurā definēti galvenie kvalitātes principi. Latvijas Zemes dienests jau kopš 2005.gada strādā pie kadastra kartes kvalitātes modeļa izstrādes, lai varētu novērtēt kartes kvalitāti. Noteikti 9 kadastra kartes kvalitātes pētījumā izvirzīti kadastra kartes kvalitātes kritēriji, kas iegūti no ekspertu vērtējumiem. Noteikti 9 kadastra kartes kvalitātes parametri ņemot vērā tās izmantošanas mērķi. Precīzākās koordinātas ir objektiem, kuros tika veikta kadastrālā uzmērīšana un tāpēc kartes kvalitāte ir tieši atkarīga no veiktās kadastrālās uzmērīšanas apjoma. Atslēgas vārdi - kadastra karte, ģeogrāfiskā informācija, ģeotelpisko datu kvalitāte, kvalitātes parametri.
