Erratum for “Topographic Maps for Construction Planning”

Topographic Maps

We call "natural" image any photograph of an outdoor or indoor scene taken by a standard camera. We discuss the physical generation process of natural images as a combination of occlusions, transparencies and contrast changes. This description ts to the phenomeno-logical description of Gaetano Kanizsa according to which visual perception tends to remain stable with respect to these basic operat...

Automatic Scree Representation for Topographic Maps

Scree – a mass of small stones covering a slope on a mountain – is extremely labour-intensive to reproduce on topographic maps when each stone is drawn separately. Th is is due to the large number of stones – typically several hundreds of stones per square centimetre in a scree fi eld. An automatic procedure to produce scree representations would therefore greatly simplify and accelerate the pr...

Automatic Contour Labeling for Scanned Topographic Maps

In many mapping organizations, existing topographic paper maps comprise the most complete source of elevation. data; the objective of this research is to capture the elevation data (which is in contour form) in a GIS. The topographic relief plate which shows no height information can be scanned into a GIS. The remaining task is then to label these isolines. This paper discusses a methodology fo...
