Activating a GIS application as an auxiliary tool for environmental forensic is based on quality of the data. Therefore, the objectives of this project are not only enhancing the existing auxiliary tools but building up a traceability system of sample lifecycle. The objectives of this project in this year contain three operations. The first is collecting data for river pollution continuously. The second is building up a traceability system of sample lifecycle. The third is optimizing data transmission for sampling trip. Traceability system of sample lifecycle is a concept of collecting all of the information from processes of environmental contamination analysis, and to manage accredited laboratories with it. It contains application system, mobile platform and management system. The system programs for sample lifecycle and for business are developed continuously. The data fields of system are specified for information added applications. Sampling information file can be developed from an embryonic form to a specification filled with data. While a sampling trip is carrying out, the sampler can use the mobile platform to get a coordinate of the sampling site and record the time automatically. The sampling positions and time could be checked by using distance and delay. In addition, in-situ sampling process filming can also provide sample credibility. The film uploading program is developed and gave suggestions for film inspection. In conclusion, to build up a data structure with high quality and high applicability, the project in this year is with the aim of developing traceability system of sample lifecycle successively. Traceability system of sample lifecycle is a more complete structure to manage accredited laboratories. In a long-term, it can give both a nice database and high applicability for forensic.
