A Geographic Information System (GIS) is an information system that allows you to place on a map and thus present various data in connection with a location, i.e. with the place which the data relate to or about which they refer. GIS allows you to combine data with maps, i.e. spatial data (location) are integrated with descriptive data - the so-called attributes of the features of these objects. This is the basis for creating, managing, analysing and placing on maps various types of data collected in databases integrated with the system. Using GIS, it is easier to present and understand dependencies, relationships or geographic context, to conduct analysis and research in almost every industry. The undoubted advantage of skilful use of the geographic information system include effective communication, more efficient management as well as more effective decision-making based on processed data - supporting the decision-making process.


This section presents information on the functionality and application of, among others modern geographic information systems such as ESRI's ArcGIS Online, the possibilities of using online applications or so-called Story Maps. The discussed information focuses mainly on issues related to the real estate market, property valuation and management with the use of GIS, planning and spatial development, and the possibilities of practical use of modern IT tools in the daily work of analysts, planners, engineers, civil-servants or property appraisers and property managers.
