A Geographic Visual Query Composer (GVQC) for Accessing Federal Databases
The paper introduces a query tool which allows users (either database experts or non-specialist users) to visually formulate and execute spatial queries directed to large federal databases that contain geospatial data. By manipulating a limited set of query modules visually, the user can correctly and quickly compose complex spatial (and non-spatial) queries with several mouse clicks. Both the underlying database model and the query language are transparent to users.
