Hybrid visual spatial QBE System For 3D web GIS

الملخص EN

Many applications use 3D geographic data, such as land management, urban planning, tourism, and e-commerce.

A related research problem is to define user-friendly systems for 3D Web GIS.

There is a need for the definition of simple and user-friendly systems to allow the users to pose queries.

In this paper, Visual query system is integrated with Query-By-Example (QBE) to support spatial queries calling it Visual Spatial QBE (VQBE), It is shown that VQBE is simple and user-friendly for most Web users.

The main strengths of VQBE are its simplicity to express queries in 3D world and its expressive power for end-users.
