Quite often we are asked to set up a dredge in an inland location where elevations are involved. The general problem is that the project may be in elevations but the dredge works in depths. For example, as I write this one of the Technical Support Team Members is working in Nebraska for a customer. The customers site is at roughly 2800 feet above Mean Sea Level ( MSL ). The dredge is to remove about 10 feet out of the pond location so the operator needs an easy way to work in both units.

In the screen capture below the HALIFAX project is being manpulated to simulate the elevation of 2800 ft MSL. In the Chart Datum box is the zero base level of the pond.

The HYPACK software now understands that the MSL Chart Datum Level of 2800 feet is to be added to the depth of the project.

The matrix was filled with a survey that had elevations in the 2790 range. Looking at the DATA DISPLAY you will see that the depth of 18 feet below water is added to the tide to dtermine that the digging tool is 6 feet below our standard pond level. The resulting elevation is the correct value for chart datum in this area.
