Mobile Documentation Service for the integrated Police System iPolSys (iPolSys mobile)

Aims
iPolSys (integrated police system) supports digital graphical simulation of accident situations or crime scenes. Inter alia it offers CAD functionalities like create, manage and analyze points, lines or surfaces. Within this project the system shall be extended by a mobile data acquisition tool to ensure a complete and highly accurate documentation and to provide a stable basis for legal decisions in processes. Core element is robust GNSS positioning.

Brief Description
The existing desktop solution iPolSys provides the processing and graphical presentation of situations with geodetic and photogrammetric methods. It supports the investigator in starting from data input over processing up to the documentation and report generation of traffic accidents and offenses. In order to offer a fully integrated system which also covers the digital data collection in the field, a mobile application with integrated GNSS module (RTK and post-processing) is developed within this project. The main target is the consideration of legal rules and regulations as well as documentation standards for the seamless acquisition of all required data. Furthermore, the risk of data loss an input errors is minimized and a reliable source of information for responsible decision-makers in processes and disputes is established.

A tablet computer represents the basis of the mobile system. It runs the data acquisition software with intuitive user interface and utilization of all available ambient and motion sensors (e.g. take pictures, measure distances and angles). An external GNSS receiver delivers the required raw measurement data for processing by the RTK module of the mobile application to achieve positions of very high accuracy. The reference measurement data is delivered by a base station with well-known position. Under limited conditions, the measured data are only recorded and later processed in post-processing on the desktop.

With this mobile unit a high-precision position determination can be offered, building the base for detailed digital data acquisition of accident sites or crime scenes. Referring to form and report specifications, the user should be guided through the strategic and complete collection of all relevant data and notified on gaps by the system.
