The article defines that the land inventory allows to form land plots of state and communal property, to fill the State Land Cadastre with information about objects and subjects of land relations and to eliminate existing errors. The aim of the article is to improve the procedure of conducting the land inventory in Ukraine, taking into account modern technologies within the current regulatory framework. The methodology of land inventory using modern technologies has been developed, which includes the following components: surveying of the inventory object, topographic and geodetic works, vectorization of its territory using remote sensing data, project works, creation of a consolidated inventory plan, development of technical documentation, its state expertise, adjustment and approval, entering data into the State Land Cadastre. It is established that an effective method of implementation of topographic and geodetic works during updating of the cartographic materials is a combined method, which includes the use of aerial images with simultaneous geodetic surveying of complex areas. The use of geoinformation technologies and remote sensing data is allowed to optimize the duration and frequency of land inventory. In particular, the classification of land should be performed in the attribute tables. Ways to solve problems of protection and rational use of the lands of the inventory object have been developed. They include registration of land plots without cadastral numbers; control of compliance of land and environmental legislation, taking into account the results of land inventory for updating statistical cadastral information and making changes of the State Land Cadastre data.
