Abstract
As the Web platform continues to mature, we see an
increasing number of amazing technologies that take
Geographic Information Systems (GIS) visualization
applications to new levels of power and usability. By
integrating new powerful technologies into GIS
systems, we get higher performance results with
additional functionalities. The most recent
development capturing the attention of the browser
based application developers is AJAX (Asynchronous
JavaScript and XML). In this paper we present a
generic and performance efficient framework for
integrating AJAX models into the browser based GIS
Visualization Web Services systems.
1. Introduction
AJAX [3] is an important web development model for
the browser based web applications. It uses several
technologies which come together and incorporate to
create a powerful new model. Technologies forming
AJAX model such as XML JavaScript, HTTP and
XHTML are widely-used and well-known. High
performance Google mapping uses…
