Penggunan web gis oleh pihak berkuasa perancangan : tinjauan kandungan dan tahap perkhidmatan yang disediakan

An efficient planning process utilizes both information technology system and GIS. Both information technology system and GIS provide high capabilities in support decision making process, and provide accurate output that resemblance the real world situation. Web GIS is an advanced GIS and information technologies that capable to distribute spatial data in an open environment. Though, the wide used of this technologies among planning authorities didn’t reflect the exact used of web GIS for planning purpose. The main question emerge from this issue is, what are the exact web GIS content and services that suitable for planning authorities to serve the public interest, as well as planning agencies. Based on the issue, a study is made on the web GIS contents and level of services. Samples of web GIS from Malaysia and USA are teken into consideration. Observation study are done to analyze the content of web GIS. The Level Of Services (LOS) are analyze base on the Level Of Contents (LOC) and Level Of GIS Functions (LOF). Cross Tabular Matrix (CTM) approach are used to determine the level of services. LOS are rank from level A1 (lowest level) to level D4 (highest level). At level A1, the web GIS services are focus on delivering general information to the public. Level D4 represent the highest level of web GIS services, which is distributing information that supports decision making in planning process. Trough out the analysis, two web GIS; AGISwlk and OLIVER, were identified as web GIS under level D4. At the end, this study will come out with suggestions of guidelines to develop a web GIS suitable for planning authorities. The suggestions are made based on web GIS functions requirements, services and applications needed, identification of focus group and the user requirements, interface GIS functions and menus, and suitability of web GIS softwar

A GIS approach in evaluation of metropolitan green area : a case of Sungai Pulai Wetland

Wetlands are among the most important ecosystems on Earth as it improve water quality, control floods, regulate global carbon levels, have significant cultural and recreational values, and also provide habitat for plants and animals uniquely adapted to living in the wet conditions. However, through progressive management, wetlands have been modified from their natural state by the influence of man. Chapter 22 in the 9th Malaysian Plan cater for environmental resource protection which shows the government’s concern on environmental aspect in the future development. Therefore, any type of development planning in wetland areas should present serious consideration on planning guidelines as well as elements that may possibly threaten the natural condition in order to conserve the environmental and ecological attributes of the wetlands for the benefit of future. One of the basic problems in planning for the management of mangrove and other natural resources is to correctly evaluate the environmental, economic, legal and social issues existing on the resource. As integrating all these datasets required for wetland and mangrove management is usually difficult, there is a need for an approach to speedily identify the types of suitable development. A study on Ramsar area involving Sungai Pulai in the state of Johor was done using the GIS application, with emphasis on sustainable wetland issues. This paper will discuss the appropriate wetland management guidelines and suitable tourism activities for these areas as identified in the study based on the use of the multi criteria analysis approach
