In the past, the Malaysian Department of Survey and Mapping (JUPEM) relied on CAD technologies to publish hardcopy maps for public requirements. When the need for a GIS database increased tremendously, JUPEM, as the authority in survey and mapping, took a leading role in providing spatial data. The department’s mandate was to develop an enterprise GIS and mapping system that produces sophisticated, integrated spatial information that would be readily available to both the country’s decision makers within various government departments and to the public.
The Project Objectives:
Using GeoMedia GIS technology to facilitate seamless access across a variety of applications and formats, JUPEM streamlined daily mapping workflows and reduced the time and cost associated with the creation, modification, and extraction of geospatial data. In addition, Intergraph TerraShare speeds the management and distribution of geoimaging data across the enterprise.
Through the creative use of GeoMedia Professional and other software, thousands of existing CAD files are now automatically and effortlessly transformed into GIS datasets to be warehoused in an Oracle 9i™ database. Now, JUPEM data can be exported in various GIS formats as required by the public.
In an effort to promote the use of spatial information among the general public, JUPEM created Multimedia Map, an interactive, user-friendly, and low-cost multimedia mapping application based on GeoMedia technology. The interactive multimedia maps are delivered together with the geographic data of the country as well as an integrated, stand alone application to view the maps.
The application serves as an introductory tool, which helps potential GIS users to take the first step in learning GIS. The multimedia application contains many tools similar to those used in typical GIS – including browsing and navigation tools, zooming in and out, and more.
The interactive geospatial tools have been successful in meeting JUPEM's objectives. More than 20,000 copies of Multimedia Map have been distributed to the public. Users from remote villages to the bustling towns have taken advantage of the application’s benefits. In addition, several government departments have used the electronic maps creatively to enhance their spatial data management and spatial information-based operations. The overwhelmingly positive response to the application prompted the Malaysian government to honor Multimedia Map with an award for innovation.
In addition, JUPEM is exploring and prototyping interactive Web applications to provide “map-on-demand” and “cartography-on-the-Web” capabilities that will enable users to specify their area of interest; indicate their choice of layers and themes; spell out their line styles, colors and labels; and choose the output format – hardcopy, digital GIS data format, or multimedia electronic map application– all through the Internet. Built on GeoMedia WebMap Professional, the system consists of five components: Data Filtering and Extraction, Cartographic GIS Database, Web GIS, Output Format Selection, and Web Cartography.
The objectives of the “cartography-on-the-Web” prototype are to make the public aware that JUPEM’s spatial data is available and to provide advanced cartographic services and spatial data management via the Web. This Web capability enables users to select preferred area, theme, color, and style criteria for required maps. Relying on GeoMedia WebMap Professional, the application will also enable the public to conduct GIS analysis over the Web, and purchase GIS data for personal use.JUPEM’s significant investment in innovative technologies provides better services and information to the public. By promoting geospatial information awareness, governments can enhance decision making processes and the public can use its access to geospatial information as a powerful tool to voice concerns.
