EQUIPMENT AND SOFTWARE
MCDI collects soundings using our dedicated hydrographic boat equipped with an Innerspace 455 survey grade echosounder with a 200 kHz, 8-degree transducer. The Innerspace 455 sounder is a single frequency (200 kHz) sonar. Innerspace rates the 455 hydrographic sounder to have 0.1 foot vertical accuracy +/- 0.1% of depth. The hydrographic sounder is connected to a Trimble DGPS (rated by Trimble to have sub-meter differential accuracy), which provides horizontal positioning of each depth sounding. Water surface elevation at the time that the soundings are collected is calculated in relation to a vertical control point in very close proximity to the project area. A Topcon GTS3C total station and prism pole or Pentax Autolevel are used if needed to determine the water surface elevation in relation to the vertical control point elevation.
Data is collected using Hypack Max hydrographic software. The hydrographic sounding data is processed using Hypack Max and Surfer terrain modeling software. The resulting information is then georeferenced to the appropriate state plane coordinate system or a coordinate system designated by the client and published using AutoCAD.
