Detailed Outline of Data Trajectory

Campbell Scientific for communication between datalogger and PC. It consists of 8 modules of which only two are

directly needed in the data trajectory.

The StgModule component retrieves files from the SM192 Storage Module. All data is kept in the same structure

and sequence as in the datalogger. The entire contents of each single SM192 file is stored in a corresponding ASCII

file on PC.

The Report component, often referred to as Split, is used to restructure and separate these ASCII files according

to the required file/table structure of the user, transfer the Julian dates to months and days, and store the result in

a comma separated ASCII file. The latter format is preferred to import external data into MS Access.

Final data processing is accomplished in MS Access in a number of pre-defined tables and queries. Lastly, the

measurements are appended to the appropriate tables in the MS Access based Lake Victoria Basin Database.

2.4 Comprehensive Data Trajectory

In order to arrive at a complete understanding of the interconnections between the various hardware and software

elements that play a role in the data flow, table 1 presents a comprehensive overview of the entire data route, from

initial measurement to final dissemination. It shows the place and function of the respective hardware and software

items, and their interrelation. It furthermore lists in a sequential order all necessary user actions.

Not all steps described in table 1 are covered in this manual. They have been presented for the sake of completeness

and to come to full insight in the whole data trajectory. Issues treated elsewhere include step 1 and 2, which are

covered by the operation manuals for both AWS and AWLRS, and step 8 and 9, which will be dealt with in a future

version of this manual or in a separate document.

Consequently, as already indicated in paragraph 1.1, the current version (1.1) of this manual covers in detail step

3 to 7.
