DATA PROCES.SING SYSTEMS 5.1 General The data processing stage of the project lias necessary to accomodate the conversion of a variety of logger output formats to il. standard compatible data form used by computer analysis packa.ges. As well, existing data needs to be converted to a similar format to reside on the data base. A number of systems exist which cater for the processing of logged data. These include 'DATMAN and LOGIN', 'HYDSYS' processor and 'system Design Services' (SDS) editing systems. Al though the latter two packages have not been used extensively, they each have known limitations which disadvantage their selection to fulfil the capacity required. The SDS editor exclusively operates to process data from that company's loggers and the 'HYDSYS' processor was developed subsequent to both other packages. The requirement to develop a custom software package was therefore an integral part of the proj ect. I DATI1AN and LOGIN' was developed under a consultancy to specification and is described below. 'Ihe backlog of existing data may be processed using spreadsheet routines which are readily available, however experience wit:::! 'LOGIN' has shown this program has advantages which will facilitate easy data input since it designed to specifically accomodate time series data. 5.2 DATMAN and LOGIN A standardised data logger output format currently exis:t this aspect cn although proposals have been made a national basis. Consequently, does not to unify raw data output~ formats are unique to individual logging systems and need to be converted to a general time series form commonly required by computer analysis software. A custom processing package was therefore devised to treat the logger outputs generated by i:he trialled systems. That is, the "Mindata",
