Developing Gis-Based Disaster Management System for Local Authority – Case Study in Malaysia

Abstract

<p><strong>Abstract.</strong> This paper describes the development of geospatial-based disaster management system for an agency at regional level. Important aspects of the system such as spatial data, geospatial database, interface and specific modules for the disaster management system form major discussions of this paper. The <i>Pengerang Disaster Management System</i> (PDMS) is being developed for a local authority in one of the Malaysian states who’s been given a task to monitor the surrounding environmental aspects. The local authority manages one of the largest oil and gas refinery plant in South East Asia region in collaboration with national oil company, PETRONAS. The PDMS, is a one-stop centre (dashboard) for managing the operations with other agencies or stakeholders such as police, marine, army, medical team, fire and rescue units. We anticipate many aspects of disaster management could trigger from this pilot project and thus provide some interesting ideas for a local authority in managing man-made disaster such as fire, other oil and gas related incidents. Some features of the developed system such as online map publishing services, data flow and other geospatial analysis during the event will be discussed in this paper. Near-future work and a big picture of the disaster management approach (with an emphasis to oil and gas incident and scenario) also will be highlighted.</p>

An Important Landmarks Construction for a GIS-Map based on Indexing of Dolly Images

“…If the intersection point between three segments that means we need to save four images associated with this point feature class such as points (1, 2 and 3). In the case of point (2), the first image represents segment (3), that means the picture is taken when moving from segment (4) to segment (3). The second image represents the segment (5), that means the picture is taken when moving from segment (4) to segment (5).…”

“…We note the point (1) is the intersection between the sequential segment and it has four saving images (1-4) from the Table 1. The image (1) represents the view between the segment (1 2), while the image (2) represents the view shot between the segment (3 2), images (3,4) represent the view between the segments (2  1) and (2  3) consecutively. Thus, the image (1) is displaced.…”

“…The output display of the route (1,2,9,4,5) For map display output of other cases routes in Figure 5 can be extracted as in the manner described above. Figure 7 and 8 illustrate the output of a map with images for the route (16,14,12) and route (8,9,4,3,2,7).…”

“…GIS (Geographic Information System) are generally well-defined as an information system that analyzes, manipulates and manages the spatial data. GIS is used to produce information that is useful in decision making [1][2][3][4][5][6]. A GIS depends on an organized database that describes the world in geographic positions.…”
