Abstract
Paper-based raster maps are primarily for human consumption. Todays computer services in geoinformatics usually require vectorized topographic maps, while the usual method of the conversion has been an error-prone, manual process.The system in development separates the recognition of point-like, line-like and surface-like objects, and the most successful approach appears to be the recognition of these objects in a reversed order with respect to their printing. During the recongition of surfaces, homogeneous and textured surfaces must be distinguished. The most diverse and complicated group constitute the line-like objects.In this article, a possible method of the conversion is discussed for line-like topographic map objects. The results described here are partially implemented in the IRIS project, but further work remains. This emphasizes the tools of digital image processing and knowledge-based approach.KeywordsGeoinformaticstopographic mapsraster-vector conversion
