Issues of Geo-Spatial Involvement in Decision Making under Local Government Power: A Participatory Approach

Abstract

This research aimed to investigate the use of geo-spatial information product in decision-making within area under local government. The choice of methods is of crucial importance in the understanding and adoption by the potential users. The efficiency of symbols and readability of information is paramount in conveying information. Observation of the local population's use of language and symbology was incorporated into this work in order to show possible representations that would be more meaningful to the reader.The base of the geo-spatial product developed in this was developed our research on the impact of urbanization on ground water resources. The research examined the urbanization impact on ground water quality and level translated through nitrate level and ground water level. The use of maps as decision-making tools with different symbol representation of nitrate and water level presents a potentially simple method for decision makers who are not necessarily experts, but are the ones making the final political decision. The collection and processing of multi-source data requires the reorganization of the data in a meaningful way.
