Historical Geographic Information System




GIS was originally developed for use in Environmental Science s, military and for computer assisted Cartography . The tools developed for these uses are ill suited for the features of historical data.




TECHNIQUES USED IN HGIS

  • Digitization and georeferencing of historical maps. Old maps may contain valuable information about the past. By adding coordinates to such maps, they may be added as a feature layer to modern GIS data. This facilitates comparison of different map layers showing the geography at different times. The maps may be further enhanced by techniques such as Rubber-sheeting , which spatially warps the data to fit with more accurate modern maps.

  • Reconstruction of past boundaries. By creating Polygon s of former administrative sub-divisions and borders, aggregate statistics can be made compared though time.

  • Georeferencing of historical microdata (such as Census or parish records). This enables the use of spatial analysis to historical data.
