ICT technological revolution has inadvertently changed the way people share and disseminate information. Today, information sharing has been made possible globally; people are empowered to contribute skills, knowledge and expertise regardless of their physical location, hence, the emergence of crowdsourcing. This new concept is evolving in many fields ranging from world mapping, health monitoring, disaster relief to crime prevention. Many studies have shown that crowdsourcing serves as a promising new approach in gathering information. Success stories by Google, OpenStreetMap, and Wikimapia inspired organizations including local authorities to try this new method for their own use. In this paper, we evaluate 6 mobile applications which use crowdsourcing to report crime related incidents. The evaluation is done based on 7 criteria that are found to be important based on literatures. These include map viewing, crime listing, incident sharing, authority reporting, media sharing, tutorial and supported system. A conclusive evaluation is performed and future works related to this research are discussed at the end of the paper.

December 2014 flooding in Kelantan river basin caused severe damage to economic and social infrastructure and dealt a serious blow to Kelantan state economies. Mitigation of flood disaster can be successful only when detailed knowledge is obtained about the vulnerability of the people, buildings, infrastructure and economic activities in a flood risk area. Therefore, to identify a community's flood risk, pre-disaster financial instrument will be introduced as non-structural mitigation measures know as flood insurance rate map. This instrument will be developed based on geospatial technology using satellite images, topographic surveys, cadastral map, type of community building such as residential or commercial and households’ income. Flood hazard maps and flood insurance rate map will provide the flood risk zone and flood insurance rate and premium coverage for the affected community. In additions it helps to determine the type of flood insurance coverage is needed since standard homeowners’ insurance doesn't cover flooding. Flood insurance rate map will provide affordable insurance for property owners, based on the lower the degree of risk state in flood hazard map, the lower the flood insurance premium. These insurance rate map are valuable to communities because it creates safer environments by reducing loss of life and decreasing property damage, allows individuals to minimize post-flood disaster disruptions and to recover quicker.
