Tower Hydrographics (UK) Ltd.

Tower Hydrographic Software, Windows based, flexible, fully configurable and above all, easy to use.

Hydrographic/Bathymetric Surveying

This program is designed to carry out real-time data acquisition for bathymetric and geophysical survey operations.

The Tower management and support team are all qualified and experienced Hydrographic Surveyors and/or Engineers, ensuring that the Hydrography application is fully appreciated and understood, and therefore reflected in the software products and support.

In addition to those standard features, this real-time program has the following capabilities:

• Echosounder and heave data can be logged as quickly as it is received.

• Fix marks and various annotations can be sent to the echosounder and other devices.

• A profile window can be displayed to show sensor data as gathered.

• DXF display routines are available to show soundings and coastline files.

• Multiple tide gauges can be used, or tides can be calculated from the GPS.

• Data can be adjusted in real-time for latency.

• Option for GeoTiffs to be displayed online to confirm pock marks, seabed objects and general seabed topography (mosaicing of side scan sonar data/records).

In addition to those standard features already outlined, the data processing program has the following capabilities:

• Manual or automatic editing of sensor data to remove spikes and anomalies.

• Selection of soundings to create a reduced data set (eg. shoalest soundings) before further processing for charting and DTM creation.

• Adjustment of echosounder data for the following:

• Tides.
• Heave.
• Change of datum or vessel offset.
• Change of sound velocity.
• Time deskewing for navigation delays.

• Output of soundings in Admiralty or engineering style, and chart production to Admiralty standards.

• DTM routines to create contours, sections, volumes, and 3-D models.

• In-built CAD routines to edit and plot background data as well as track and soundings.

• Batch processing of charts.
