Welcome to Clydeside Surveys Limited.
The processing suite has been designed to be portable and can be loaded both onto laptop PCs for field use, as well as larger PC’s for final data presentation in the office.
The software makes extensive use of commercially available programs for the data presentation aspects of a project. In particular all graphical plotting is undertaken in a CAD environment reducing the need to develop specific printer drivers.
The final plots can therefore be provided as files suitable for printing, or in a standard exchange format such as .DXF. The main processing and editing functions are handled by specially written code. This has a number of advantages, notably in that information on all major editing and processing tasks carried out is logged into a separate Quality Assurance file.
Inadvertent editing of data through the use of powerful spreadsheets or commercially available editors can result in significant amounts of restorative work or, in extreme cases, erroneous results.
The presentation of time series data, typically the result of long term deployments of recording instruments, is mainly concerned with principal physical parameters such as currents, waves, tides, weather and water quality information.
The Clydeside Surveys data processing package typically stores these data as direct access files with each data point associated with a quality flag which stores information on the data point such as valid data; interpolated value; or erroneous data. In the latter case the data would be masked such that it would not be used in subsequent data processing tasks.
Data can be input to the data processing package as ASCII files or as raw data from oceanographic instruments (Aanderaa sensors, Interocean S4 current meters, RDI Acoustic Doppler Current Profilers, Braystoke current meters, Waveriders etc.). Standard processing packages include harmonic analysis, tidal or other digital filtering and spectral analysis.

The data presentation packages are written to facilitate the merging and comparison of different data sets. For example tidal data, wave data and current meter data from three separate files can be presented on a single plot without the need to first merge the data into a single file. Each individual file contains time information, these data sets are used to ensure that the data is plotted to the correct position on the final plot eliminating the possibility of mismatched time series.
The program suite is under constant review and development of unusual or non standard types of data presentation can be incorporated to suit client requirements.
The collection and processing of survey data is one of the key areas of expertise within Clydeside Surveys and its associate companies. The experience gained in developing the software techniques to present oceanographic and environmental data has also been applied in the development of software based real time data collection and display systems.
The collection and processing of oceanographic survey data is different to time series data in a number of ways. The data tends to be collected over shorter time scales but often covers greater geographical areas.
A greater degree of control over the data is also possible since Clydeside Surveys would generally be involved in both the data collection and processing aspects of a project.
A strong emphasis is placed on quality assurance during the data collection as well as on automating the routine aspects of data collection to as great an extent as possible. The use of automatic logging and relevant graphical displays allow the field staff more time to plan the survey and maximise useful data return.
Typical types of data that are routinely processed include:
