The study of spatial information includes interaction with data sets and maps related to solving a specific issue, which is best implemented in geographic information systems (GIS). A some set of digital spatial information constitutes spatial data. They consist of two interconnected parts that form a description of the spatial position and thematic content of the data; positional (topological-geometric), and non-positional (attributive). One of the basic (elementary) types of spatial objects that modern GIS operates with is usually considered a point (point object) - a 0-dimensional object characterized by plan coordinates. Depending on the type of object, its location is determined by a pair (triplet) of coordinates organized in a certain way within the framework of some data model. The list of properties corresponds to the attributes of an object, its qualitative and quantitative characteristics. The conditions under which an entity is displayed as a point object can be expressed by the following provisions: • spatial arrangement of the entity (is important); • metric dimensions of the entity (are not important); • the size of the object is not expressed in the scale of the model. An important property of turned objects is that they are independent of each other. Attribute data in a GIS provides a link between the location of a symbol and its meaning. Most often, this is a Character, Number and Date. All the described properties are possessed by the objects that are used in the implementation of the MONITOX project, and in particular the creation of a system for monitoring environmental pollution.
