Consider adding spell-corrector for full-text search to give users more chances of finding data. Improve functionality of docBUILDER and metadata ingestion tools. Capitalize on Google cache and provide additional mechanisms for accessing metadata (metadata in KML). Use semantic web technology to offer the option to search on related words to their original query.
