Index Crimes: A Web Geographic Information System Platform for Crime Mapping Frequency in Butuan City

The Butuan City Police Office (BCPO) requires an efficient system to monitor index crimes in Butuan City, which is currently lacking, impeding effective crime prevention.This study aims to develop a user-friendly web mapping service adhering to Open Geospatial Consortium (OGC) standards, integrating statistical and graphical interfaces with geographic information systems (GIS) for crime mapping.The system will display data analysis by barangay from 2019 to 2023 using a GeoJSON map with gradient colors indicating crime frequency.Crime frequency will be classified into four color intervals, with bar graphs showing hourly and monthly data and pie charts depicting the annual percentage of index crimes per barangay.This GIS-based web interface will provide a comprehensive visualization and analysis of crime data, enhancing the BCPO's ability to effectively prevent and intervene in criminal activities.
