The system indexes and provides search features for GIS records from the website for the USGS Board on Geographic Names (http://geonames.usgs.gov/).

The system builds and maintains several in-memory indexDatabaseByName data structures to support the following operations:

• Importing new GIS records into the databaseService file
• Retrieving data for all GIS records matching a given feature name and state
• Retrieving data for all GIS records that fall within a given (rectangular) geographic region
• Display the in-memory indices in a human-readable manner
