Davao City’s economy has risen significantly and it has brought job opportunities to the people. Along with this, newly built infrastructures were also sprouting within the city. Safety of the area before building the infrastructures must be first taken into consideration to secure the lives of the people. Hence, the researchers came up with this study that aims to develop an application to aid land developers, geologists, and residents of Davao City in assessing the geologic safety of an area. The web application system uses Google Maps API V3 to display areas in the city which are prone to geologic terrestrial hazards. It can also display the soil and rock map of Davao City. The application also caters online request and release of Geological Assessment Certificate which is a requirement by the Department of Environment and Natural Resources (DENR) before constructing new infrastructures. The researchers gathered requirements and information from Mines and GeoSciences Bureau (MGB Region XI).. The application was tested by the Geologists and IT Staff of MGB, Laboratory Technician of Department of Agriculture, Civil Engineer instructors of the University of the Immaculate Conception (UIC) and other individuals.
