PROBLEMATYKA GROMADZENIA, PRZETWARZANIA I UDOSTĘPNIANIA DANYCH GEOPRZESTRZENNYCH

Abstract

Aim of the study: The paper describes the problems of collecting, processing and sharing geospatial data on the example of the National Geodetic and Cartographic Resource (GUGiK). The Central Office of Geodesy and Cartography (GUGiK), on the basis of the acquired data, prepares spatial databases for the whole country, such as the database of topographic objects (BDOT) or the numerical terrain model. These data are used for further studies, environmental analyses such as hydrographic or sozological maps of Poland. Material and methods: The article indicates what functionalities and, above all, what geospatial data are collected in the geoportal, a government map service managed by the General Office of Geodesy and Cartography. The study included a survey of the geoportal. The purpose of the survey was to obtain information on whether this service is known to potential audiences seeking information on spatial data. Results and conclusions: The survey proved that the geoportal is a popular service used to display and process spatial data. Survey respondents use a lot of the data collected in the geoportal and take advantage of its functionality. Finally, an analysis was carried out of data obtained from the District Geodetic and Cartographic Documentation Center of Małopolska regarding the number of notifications of geodetic works, the number of applications for access to materials from the PZGiK, and the number of applications for extracts or extracts from the cadastral record - for the period 2014-2019.
