Criminal maps: Android app for mapping and generating heat maps of crimes

Abstract

Crime is a serious social problem and georeferenced information systems can contribute to mapping and alerting the population, enabling risk management. The development and usability evaluation of the Criminal Maps Android application is presented, for insertion and visualization of georeferenced data, creation of heat maps and addition of alerts. The application is based on HIDDEN 1 and was developed in Android Studio, restructuring its database and functions: new icons; filters; alert by location; delete your own data; report a point. The application underwent an evaluation of its use, using Nielsen s heuristics, based on a (validated) checklist and the semiotic inspection method (MIS). The results indicated that the application has good usability, as well as potential for use.
