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)
