The City of Nanaimo wanted to provide the public with up-to-date property crime information that would be displayed on their web map. However, the data had to be anonymized for privacy reasons before it could be released. This presentation will describe how the RCMP Geomatics unit used FME Desktop to create a workspace that extracts and anonymizes the Nanaimo property crime records from a Province wide dataset in less than a minute.
