The Georeferencing Calculator is a tool created to aid in the georeferencing of descriptive localities such as those found in museum-based natural history collections. It was originally designed for
the Mammal Networked Information System (MaNIS) and has been widely adopted in other large-scale collaborative georeferencing projects to supplement semi-automated georeferencing tools. The application makes calculations using the theory given in Georeferencing Best Practices (Chapman and Wieczorek 2019), derived from the earlier MaNIS/HerpNET/ORNIS Georeferencing Guidelines (Wieczorek 2001), and The point-radius method for georeferencing locality descriptions and calculating associated uncertainty (Wieczorek et al. 2004). Specific methods for calculating a wide variety of
examples of the distinct Locality Types are given in Georeferencing Quick Reference Guide (Zermoglio et al. 2019).

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.
