About geoLoc
to assist biological collections in geo-referencing their data
the database includes approximately 110 thousand names of Brazilian localities, obtained from:
Brazilian Institute of National Statistics and Geography (IBGE) GEOnet Names Server (GNS) speciesLink/Fapesp
algorithm based on concepts in the Egaz program (Shattuck 1997) capable of calculating a coordinate for a distance and direction

About spOutlier
to assist biological collections in identifying possible suspect points in existing records
uses techniques modified from Chapman 1999 to detect outliers in latitude, longitude and altitude
allows users to indicate their data set as either terrestrial or marine
useful to biologists around the world who wish to identify possible errors in their data
future developments will allow users to submit a document on-line
