ABSTRACT:
The recent advancements in Web technologies have shown great development in bringing the 3D object to the web. Here with this paper we restrict only to the web 3D city models. There is an increasing need for 3D-descriptions of urban areas for various applications such as town planning, microclimate investigation or transmitter placement in telecommunication. But this information is not available 2D city models. This is the basic requirement for 3D city models. Also when we talk about the Technology, it is essential to discuss the cost to reach that. In this paper, the basic application areas of 3D city models and how Web 3D city models are beneficial to them are discussed along with some business models.

1. INTRODUCTION:
Instead of directly jumping into explaining the business model for 3D web city models, it is essential to give some idea about the 3D city models and its background.

So in this paper first the advantages and applications of 3D city models are discussed briefly. Later in this section, the already available Business models for the 3D city models are discussed.

2. BACKGROUND:
Web 3D models are extensively used in engineering and scientific visualization, CAD and Architecture, Medical visualization, Training and simulation, multimedia, entertainment, educational, and more.

There are three standard formats used for web 3D data as described by Web 3D consortium. One is VRML (virtual Reality modeling language) and the other is X3D.Also, it must be noted that VRML is soon to be replaced by the relatively new extensible 3D (X3D) file format. X3D is a software standard for defining interactive web- and broadcast-based 3D content integrated with multimedia (Web3D Consortium, 2004).

MPEG4 is another 3D standard used for integrating Video and 2D/3D graphics.
