Sažetak
The cadastral map of Varazdin dating from 1860 is a nice coloured map and still is in official use of the State geodetic administration. During its usage the map is substantially damaged and there is a need to protect the original and, at the same time, to make a map that will replace the original, the facsimile of Varazdin. In order to make the facsimile of Varazdin cadastral map, this paper gives results of the research of the methodology of the map making, the map content, used colours, paper and added map content. Available sources are the original cadastral map which is coloured and additional sources in form of lineart cadastral map and field cadastral sketches. The original and line-art map were scanned using a DeSkanExpress low-cost scanning system for large formats. The system scans portions of map in several strips which are merged into the single image using our own software. The terrain cadastral map were scanned by flatbed UMAX Mirage scanner of A3 format. The original map is made on high-quality drawing paper with watermark visible at natural sunlight. During the time the paper became light yellow. The map content is inside thin black ink drawn map frame. Outside the frame are meta-data: map-sheet signature, map-sheet number, cadastral area name and so on. The map content consists of parcel borders, its numbers and land use ; buildings, distinguished by its colours and public ones with their names ; street and square names with its numbers and some point signatures such as alone trees. The list of street names is outside the map frame. Buildings differ upon its colour: red (public and houses), light and dark pink and yellow ones. The rest of the content is black ink drawn and then watercoloured. During 150 years of regular maintenance new parcels with its numbers were drawn with red ink. Some signs and numbers are added with lead-pencil. At the map borders the paper is physically damaged. Some parts of paper are missing on the edge, some torn off pieces are joined with tape. Under tape paper became dark brown. The colour separation method is rejected in the start, because the map is made by hand. The paper discusses possibility of copying and inserting missing parts from additional map sources, changing the colour of the paper with white or some other colour, removal of the map content added with red ink and lead-pencil and so on. The discussion is based on practical examples on the digital image. The conclusion suggests image processing methods for optimal result of the facsimile of Varazdin cadastral map.
