Abstract: The paper describes the process of entering into the computer of the technical raster information from paper engineering and geological maps, which accompanies the reconstruction of transport communications. It is proposed to formalize the process of the automatic input and the digitiza­tion of the technical information using the proprietary software MapInfo Professional, which is a gene­ral-purpose mapping geographic information system (GIS). It is shown that the technology of working at a raster substrate allows us to combine both raster and vector layers of initial engineering map. This operation significantly increases the accuracy and speed of digitization of the input data. It has been found that such a method of the digitization does not require the involvement of the external special devices in order to transfer the needed information from the paper base to digital form one. It is proposed to use the point-based objects on maps (as the stations, the measurement points, the observations and the values of technical monitoring indicators, etc.) for digitization procedure, rather than the isolines themselves. A significant advantage of the proposed procedure there is the use of the right rectangular coordinate system and the solid coordinate point binding before the vectorization of mapping objects.
