Export Matrix

Using Eye4Software Hydromagic, it is possible to export matrix data generated from your soundings to a third party format like a point cloud or DEM/DTM file. Hydromagic will write a projection file along with the exported data so it can easily be imported in other software.

This function can be used, for instance, to bring a matrix as a point cloud into AutoCAD, or to bring 3D depth information into GIS or LiDAR software packages.

Currently, the following file formats are supported for matrix export:

More supported export file formats may be added in the future. To export a matrix in a user defined ASCII format, you could also you the ASCII Export function.

Exporting a matrix

In order to export a matrix to one of the formats listed above, make sure that the "Project Explorer" is visible and expand the "Matrices" folder.

Click the "Browse..." button to select the destination folder and file name.

Projection Files

The software will also generate an ESRI WKT 4 projection file for you. This enables the point cloud or DEMO data to be imported in most CAD or GIS software packages. The generated projection file will always have the ".prj" extension, irrespective of the selected export format.
