| Jakarta is the capital city of Indonesia with a population of about 10 million people, inhabiting an area of about 25-km by 25-km. Due to several natural and man-made factors, Jakarta is yearly affected by flood. It causes a lot of damages and creates physical, social and economic impacts. Several approaches have been implemented for flood hazard mitigation in the area. One aspect that limits the effectiveness of the approaches so far is the lack of detail, comprehensive and up-to-date spatial information of Jakarta and its surrounding areas, both in forms of maps or GIS databases.This paper will review the status and development of mapping system in Jakarta. Strengthening analysis will be performed in order to make the system also useful for flood hazard mitigation manage-ment. Preliminary analysis concluded that for flood management at least there are five maps (databases) that their making have to be added to the system, namely height contour, watershed, drainage, water penetration, and land subsidence maps (databases). Social mapping should also be performed in order to map and identify the social and economic conditions of the peoples living in the flood prone areas. Strategic issues and problems related to this mapping system strengthening will be presented and discussed. Paper will be sum up with conclusions and recommendation along with plans for future activities. |
