On the other extreme, Level D4 represents the highest level of web GIS services which is distributing information and getting feedbacks to help support decision making in planning process. Even though web GIS was seen as an emerging tool for public participation in planning Kingston et al. Table 3.
Main functions of web GIS sites. This characteristic is important to achieve the purpose of publishing data on the web. One possible reason for some web GIS sites being less user friendly is these sites target only expert users instead of the lay public.
User friendliness is here defined as sites that have menus and icons that are attractive and easy to understand by the public. The interface should also be easy enough to be quickly learned and uses common terms.
Besides user friendliness, graphics too are important to make a good web GIS site. Almost seventy six percents of the sites surveyed were evaluated as having interesting or moderately interesting graphics while the rest were rated as having rigid or uninteresting graphics. Interesting graphics are those that are easy to the eyes and make full use of colours, sizes, scales and arrangement. The assessment, however, was purely based on the authors personal experience and taste.
In addition to appearance of the web sites, their contents were also evaluated in term of the details of the maps presented and the sophistication of their menus.
All the three sites that had only general maps were Malaysian sites that were meant for regional planning purposes, the planning level that does not require maps down to individual lots.
Geographic Information System (GIS) Web Applications
Examples of sophisticated menus are menus that allow users to perform certain types of spatial analysis such buffering, neighbourhood analysis, etc while common menus allow users to perform standard operations such as zooming, panning, etc. Table 4. Characteristics of web GIS surveyed. All of the total web GIS sites surveyed serve some planning functions that qualify them to be a planning information centre or a planning support system except for two Malaysian web sites that can only be categorised as an information centre.
These web GIS sites not only contain detailed planning information but also allow for interactive access of the information using advanced GIS functions for analysis and community participation purposes. These web GISs are designed as a planning information centre or a planning support system.
It has thirty interactive map applications and twenty nine browser-based mapping functions for display and retrieval of spatial information.
It also has a collection of satellite images for display. Table 5.
There are however still a considerable difference between the two countries concerned in the functions and LOS of the web GISs sampled, although there is not much difference in other areas. This reflects the maturity of web GIS development in the country as indicated by the numerous number of web GIS sites currently in operation compared to the number in Malaysia. The study also shows that currently in practice the two most important functions of web GIS are distribution of planning information and supporting of decision making process.
However, the study also shows that not all local authorities have the same uses for their web GIS. In general, there are three levels of web GIS users which are the administrative users, expert or professional users, and general users or the general public.
Identifying the targeted user groups and their requirements helps determine the structure, appearance and contents of a web GIS that can fully serve its functions. Figure 1. An example of a Web GIS structure for a local authority Last and certainly not least, deciding on what software to use is also crucial.

Commercial softwares might be costly but they come in one simple package and with technical support while most of the zero-cost open-source softwares need to be customized using source codes or toolkits, or combined with other softwares. While open-source softwares might not be for the uninitiated, they have higher flexibility than the commercial ones.
Either commercial or open-source, the choice of software depends on the budget, web GIS needs and technical know-how of the organization. Kuala Lumpur, Malaysia.
