GEOLocate is a comprehensive electronic georeferencing solution funded by the National Science Foundations
and developed by Tulane University's Museum of Natural History designed to facilitate the task of assigning
geographic coordinates to specimen locality data associated with natural history collections.
It is similar to how google maps helps find your house
or the nearest Starbucks, but instead of deciphering addresses, GEOLocate
analyzes specimen locality descriptions. Unlike addresses, locality description
of specimen collections are quite varied and oftentimes difficult to pinpoint.
Therefore, GEOLocate also provides an interface to visualize and correct as
nessesary the results of automated georeferencing.
To answer this, we randomly selected 100 unique hand-georeferenced locality records from the TUMNH fish collection database. Each record was initially verified against digital maps for accuracy of its coordinates. Inaccurate and non-continental records were removed from the test dataset. The data were then georeferenced using GEOLocate and Biogeomancer and the results were compared against the original hand-georeferenced coordinates (Table 1). GEOLocate and Biogeomancer use similar gazetteer data for the United States, but employ different georeferencing algorithms. GEOLocate also supplements its core gazetteer with additional data such the river & road networks, legal land descriptions and river miles. Both tools had comparable accuracy, as indicated by the similar means and standard errors of distances between computed and hand georeferenced coordinates. However, Biogeomancer was only able to georeference 39% of the records, whereas GEOLocate was able to use its additional data sources to accurately georeference 95% of the records. Moreover, GEOLocate has the added feature of allowing the user to visualize and adjust coordinates for all of its determinations. An independent assessment of georeferencing tools published in 2004 also found GEOLocate to be the most accurate and efficient of computer-based georeferencing solutions available at that time
(Murphey et al. 2004).
