  Today a lot of digital evidences for crime investigation includes a
geospatial component. This data comes from various sources such as smartphones,
tablets, navigation systems, digital camera with global positioning system
(GPS), etc. The geospatial data plays a crucial role in crime investigation
such as helping to tracking suspects, profiling serial offenders, recognizing
trends in criminal activities, just a few. Many techniques and Geographic
Information Systems (GIS) tools have been used to extract, analyse and
visualise geospatial data. However, in some specific circumstances, the
existing tools are not suitable for use as they do not meet investigators
needs. This paper presents a bespoke forensic GIS tool based on specific
requirements of the investigators of a law enforcement Department. Firstly the
paper discusses some existing forensic GIS tools and environments in practices,
and then it presents some investigators requirements and show the unsuitability
of the existing tools. The paper continues with the presentation of the system
architecture of the new tool and its components. It also introduces various
applications and use cases which have been deploying at the Department as an
evaluation of the developed tool.
