The Hydro Survey application provides all that is required to conduct a basic hydrographic survey, using the ISA500 as a single beam echosounder.
The main screen provides a graphic readout of the ISA500 Range reading, Temperature, Heading, Pitch & Roll. A 3D graphic is provided of the ISA500 to tell at a glance the unit’s attitude.
Initially a 2D graph is provided, showing present location. As the ISA500 is moved, the movement is detected via GPS and a top down view of the path travelled is presented.
The grid size can be scaled to suit the resolution required from the survey.
At any time, the graph can be switched to 3D mode, showing the subsea terrain data gathered.
All data is logged to a separate CSV file, allowing re-load into the application at a later date, or post processing.
GPS is fed into the application ensuring that all data is correctly geo-referenced.
Along the lower of the screen, buttons are provided for connecting to and configuring the ISA500. Further buttons allow the unit to be interrogated, survey files to be opened, a new survey started, logging on and off, 2D/3D graph selection, scale input and extents to automatically show all data gathered. GPS status and output is also shown in real-time.
