Abstract

The goal of this contribution is to give comprehensive information about methods and techniques of digitizing and on-line publishing of old cartographic products. Different types of scanners and suitable processes for digitizing of cartographic products are reviewed out in order to get a digital image of desired quality. Different possibilities are mentioned for online publishing of old maps and their advantages and disadvantages. Emphasis is placed on cartographic properties preservation of digital copies of old maps. Possibilities of an added value extracted from digital maps are shown with comparison of original paper maps.
A question of suitable raster formats for digital images of maps is discussed as well as their advantages and disadvantages. Properties of formats for the Zoomify application and especially formats for digital map publishing via Web Map Service (WMS) are mentioned in details. The whole process is shown on a project of digitizing and publishing a set of Special maps of the 3rd Military Survey. This project was realized in the digitizing centre of the Research Institute of Geodesy, Topography and Cartography which is shortly introduced. In the end, recommendations for map collection managers, archives and libraries are given in order services for readers and researchers cloud be provided by those institutions in the most useful way.

Author's professional CV

Milan Talich was graduated from the Czech Technical University in Prague, Faculty of Civil Engineering, Department of Geodesy and Cartography. Then he was engaged in the Research Office of Geodesy, Topography and Cartography (VÚGTK), working since 1987 in the International Center on Recent Crustal Movement (ICRCM) at geodetic networks processing and geodynamic problems. In 1992 – 1993 he was at one-year stage in the Institute of Applied Geodesy in Frankfurt/Main (IfAG), where he compiled the Czech, Slovak and Hungarian parts of the European Reference System (EUREF) GPS network. Then he was engaged in solutions of GPS processing oriented to geodynamic applications and to questions related to deformation analysis of those data. Since 1995 he solved some problems of informatics in the Branch Information Centre (ODIS) of the VÚGTK. At present he works at information systems oriented to web. In 2002, Milan Talich presented his doctorial thesis „Information Systems to On-Line Providing of Geodetic Information and Their Creation“.
