Georeferencing Calculator

The Georeferencing Calculator is a java applet created as a tool to aid in the georeferencing of descriptive localities such as those found in museum-based natural history collections. It was specifically designed for the Mammal Networked Information System (MaNIS) Project and has been adopted as well by HerpNet and ORNIS. The application makes calculations using the methods described in the Georeferencing Guidelines. This application was adapted by Craig Wieczorek and John Wieczorek from an earlier version in Java by John Wieczorek with contributions from Qinghua Guo, Carmen Boureau, and Craig Wieczorek.
