This will identify individual data sets generated from each test. The system will allocate only eight characters for alphanumeric IClbelling, imposed as a result of the limitations on the Mindata logger. Therefore only vital data can be used for labelling. That is, data pertaining specifically to the role of the dat,a set only. Each test, consisting of a number of data sets, requires identification to suitably locate it in the context of each project. For example, a project consisting of a step drawdown test, constant discharge test with three observation bores and recovery will eventually produce nine data sets pertaining to water level movement and three to flow monitoring. Readings of 'later conductivity, temperature and pH .lith time will form at least separate three files. If unvented transducers are used, a further three data sets will be generated. The system of data logger data set labelling J.S proposed in Appendix E, and is based on the "Tree" directory system. It pre-empts the introduction of the HYDSYS groundwater data base system, however, since a substantial accumulation of data is expected in the lead up period until its introduction, an interim system needs to be adopted. Systematic file naming is important when used in the data interpretation stage since uniqueness and ease of recognition of data files will facilitate efficient data handling. 6.3.2 Processed Data Processed data encompasses the spectrum of data that is generated and processed using 'DATHAN' and existing data which has been input through the keyboard and is ready for archival.
