Web Portal

Information sharing

Introduction

Once services have been implemented for different SDI nodes, a common practice is to facilitate their access by building portals. Spatial web portals can be thought of as a gateway that provides access to geo-resources via geo-webservices on the Web. A web portal is simply a website that gives visitors organized access in a unified way, typically through catalog services, to geo-resources on the Web, and preferably also to the people and organizations offering those geo-resources (see Figure 1). A portal potentially offers access to many other sites. Consequently, a web portal can also be used to aggregate content.
