Abstract: Land cover objects are reflected by georeferential data. Georeferential data are the geo-data of universal use on the most important topographic, engineering and geodetic objects [5]. Georeferential data are updated throughout the world. Georeferential data are not only used for mapping but are also becoming an important basis for integrating. These trends are supported by the INSPIRE Directive, which is based on the fact that spatial data shall be created once and used at various levels, and their accuracy and reliability shall be strictly regulated [2]. Orthophotographic maps are most commonly employed to update georeferential data. It is also important to note that the processing of geographic data includes the interactive revision of data, therefore the responsibility is borne by the operator himself/herself [3]. Taking into account the fact that GIS is applied in more and more research areas including not only land management but also soil science [4]. It is essential to process and provide any spatial data so that they would result in effective analysis and adoption of correct planning solutions [1]. The research aimed to update the georeferential data in the selected area. To achieve the aim, the following tasks were set: To update the data of built-up areas, areas overgrown with trees and bushes, dams, pools, lakes, ponds and roads in the selected area; to perform the analysis of changes in the data under investigation. The object of the research includes layers of built-up areas (pu0), roads, dams, pools (hd4), lakes, ponds (hd3), areas overgrown with trees and bushes (ms0) in a part of Igliauka elderate, situated in Marijampole municipality. Updating the layer of built-up area, it was determined that its total area increased by more than 1%, i.e. 23763 m2
