This table shows the breakdown of ANSP mollusk occurrences by continent or region sorted by the proportion that have been georeferenced. Records refers to the number of records in our database to which we have assigned a country and a continent; Georef'd is the number of those records for which our process has assigned geocodes; and Unique is the actual number of unique pairs of geocodes. We have multiple mollusk occurrance records associated with many of these localities.

Continent/Region		Records	Georef'd	Unique	%
Australia		28537	26875	1128	94%
South America		13207	11044	1047	84%
Africa		25997	19962	783	77%
Oceana		24115	18504	534	77%
Central America		9988	6930	252	69%
Asia		52032	15012	205	29%
Europe		17823	2797	33	16%
Caribbean		33209	5022	23	15%

We have worked our semi-automated georeferencing project by continent (or region), focusing on countries. We began with Africa and South America, continued with Australia and Oceana, and then have been working north along two fronts, Central America and Southeast Asia. Thus far, we have finished a first pass on 35% of the records.

What is next?

We have been using the GeoNet database to work those localities outside of the United States. We are now in the process of moving our semi-automated georeferencing system over to the USGS datbase to deal with the bulk of the records from North America.

As the first pass over these data is completed, we will begin our second passes. Again going country to country, but this time focusing attention on those localities that were not assigned geocodes during the first pass and those that are not mapping accurately.

This summer (2004), we will begin comparing the geocodes obtained from our semi-automated process to those from expedition charts and other sources to further test the accuracy of our records.
