GeoVisual Interface - A Visual Query Interface for Geographic Information Systems.
Damires Yluska de Souza Fernandes, Ana Carolina Salgado · Brazilian Symposium on Databases · 2000
This work presents GeoVisual Interface an interface for visual queries in Geographic Information Systems (GIS). GeoVisual Interface is the upper level module of a complete visual query system architecture. It allows users to formulate queries using visual elements (i.e. spatial objects from a visualization area, from the database schemas or from a geographic entity metaphor) and spatial operators via direct manipulation. Cognitive, ergonomic and technical aspects are also considered to improve the spatial query formulation capability and enhance the humancomputer interaction, making the system more attractive to users.
