ImportShapefile ( DbConnection conn, IDataClient client, string filename, string tableName, int srid ) : bool	Imports the provided shapefile into a sqlite database using the VirtualShape extension
IsForbiddenShapefileName ( string name ) : bool	Checks to make sure a given table name doesn't conflict with any of the census shapefiles
LoadShapefile ( string filename, string tableName, IDataClient DbClient, ICoordinateSystem &CRS ) : bool	Imports a shapefile into the database. Do not use this to load census shapefiles.
MakeCensusProjFile ( string filename ) : bool	Generates a proj file for a given shapefile if it's missing
