Historical geographic information system

A historical geographic information system (also written as historical GIS or HGIS) is a geographic information system that may display, store and analyze data of past geographies and track changes in time. It can be regarded as a subfield of historical geography and geographic information science.

GIS was originally developed for use in environmental sciences, 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[edit]

  • 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 rubbersheeting, which spatially warps the data to fit with more accurate modern maps.
  • Reconstruction of past boundaries. By creating polygons of former administrative sub-divisions and borders, aggregate statistics can be compared through time.
  • Georeferencing of historical microdata (such as census or parish records). This enables the use of spatial analysis to historical data.

Notable Historical GIS projects[edit]

Software or web services developed for Historical GIS[edit]

  • TimeMap — A Java open-source applet (or program) for browsing spatial-temporal data and ECAI data sets[4] Developed by the department of archaeology University of Sydney.
  • Version 4+ of Google Earth added a time line feature that enables simple temporal browsing of spatial data[5]
