As applied to natural history collections data, georeferencing is the process of determining geographic coordinates (typically latitude and longitude) from a textually described locality description. Measurements of uncertainty associated in the form of a radius from the determined point or a polygon encompassing the maximum possible extent of a locality description are usually included in the georeferencing process.<br> | As applied to natural history collections data, georeferencing is the process of determining geographic coordinates (typically latitude and longitude) from a textually described locality description.
