Abstract
Automatic Georeferencing of Heterogeneous Historic and Illustrated Maps
Highlights
Of locations and calculates the georeference information
Some algorithms apply fixed image processing techniques to find features within the map images, and try to match these patterns of features to a database of geographical information (Chen et al, 2004). The drawback with this approach is that the image processing operations used in a particular style may not work for a map created using a different style
Other techniques only work for a specific kind of map, like street maps (Desai et al, 2005) or aerial photographs (Kim et al, 2010)
Summary
Of locations and calculates the georeference information. This output information contains the northeast and southwest corners of the map, a list of mapping points, as well as the angle of north in the image (counter-clockwise, where 0 degrees is pointing up). Arriaga-Varela a, Toru Takahashi a a Stroly Inc, Kyoto, Japan, enrique@stroly.jp, toru@stroly.jp Abstract: The process of manually georeferencing or aligning historic or illustrated maps with contemporary maps can be a difficult and time consuming task (Fleet et al, 2012).
