REVIEW OF SIMILAR WORK

In the article “A Web-based browsing and spatial analysis system for regional natural resource analysis and mapping”, the authors have discussed that traditional GIS techniques and tools are lack of efficiency and easy to use delivery mechanism. For example, installation or hosting of GIS application and knowledge about geographic and GIS are required. Due to these constraints, many professionals outside GIS community have difficulties in applying GIS techniques in their practical uses. As such, more flexible and feasible web-based GIS applications are introduced.

The authors also explained about the earlier versions of server-centric web GIS applications which resulted in overloading the server. Because of performance issues as well as more flexible and advanced programming languages, client-side web GIS are now widely used by professionals in many fields. The flexible programming languages help create a customised environment for the end users so that knowledge about GIS techniques is no longer required in practical applications.

Moreover, the article gave an example of load-balanced web GIS application, WebSAS. WebSAS follows 3-tier architecture: client, application server and database. The architecture spreads out the work load in each tier and the database system provides image files so that the end user do not need understanding about geographic elements.

The key factors of web-based GIS application are efficiency and ease of use. Developers need to focus on load balancing for efficient data retrieval/access, apply proper GIS techniques, and understand end-user’s requirement from the application.
