Georeferencing Calculator Manual. Version 1.0.

Abstract

The Georeferencing Calculator (Wieczorek & Wieczorek 2020) described in this document 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 & Wieczorek 2020), derived from the earlier MaNIS/HerpNET/ORNIS Georeferencing Guidelines (Wieczorek 2001), and The pointradius 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 ([Bloom] Zermoglio et al. 2020). Underlined terms throughout this document (e.g. accuracy) link to definitions in the Glossary (the same glossary of terms used in Georeferencing Best Practices, while terms in italics (e.g. Input Latitude) refer to fields and/or labels in the Calculator. Darwin Core terms are displayed in monospace (e.g. georeferenceRemarks) in all GBIF digital documentation and link to the definitions maintained by Biodiversity Information Standards (TDWG) in the approved List of Darwin Core terms.
