Photogrammetry aerial maps help the police to track and solve crimes. Modern crime aerial maps are created on computers and they are much easier to use. Crime analysts look for patterns of crime. GIS (geographical information systems) and photogrammetry software uses Ordnance Survey aerial maps to plot many pieces of evidence and other important information. This often produces 'hotspots' of crime.
