摘要：The rapid rate of development in many domains of life,science and technologies results in a constantly increased amount of information of various types. Attempts at categorization of gathered data in logical and useful way has resulted in the creation of many information systems and development of geoinformation technologies. Because of theirs continuous evaluation it is difficult to elaborate new information technologies in which future software and hardware could be completely included. The complexity of tasks and the lack of experience in long-term operation of systems in which information technologies are used necessitate further detailed studies of the components of such technologies. Recently,there has been significant scientific and technical work on the creation of a geoportal system in Poland. Since there is no experience in the creation of this type of information system on a national scale and because of the high financial and time costs,it would be reasonable to analyze all components of the geoportal,including the technologies of obtaining and updating of data, geoinformation databases,metadata standards and the forms of the reports for final users. In this article,the disadvantages of geoinformation technology,which is used in the GIS and the geoportal,are highlighted. The complexity of georelative (three-dimensional and semantic) model data,the lack of correlation between the database content and type of user,no developments in the realm of automatic selection methods and data generalization during display,the lack of capability of presenting the database content in the hard copy form of map,etc.,are included among shortcomings. It is noted,however,that there are theoretical developments which make it possible to modernize this technology and to simplify the methods which produce 3D geo-information,without the necessity of using expensive GIS software for mass users,like civil servants (from different administrative units). The basics of the SIP-alphabet are presented. Examples of fragments of topographic maps with semantic information written on it by means of SIP-alphabet symbols is also shown.
