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).
