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. Locate the matrix file you want to export and right click the file. This will show a context menu, from which you select the "Export Matrix Data..." option.

Select Export Matrix Data from the context menu.
Select "Export Current View" from the matrix context menu.


Export matrix dialog

After selecting the matrix, the following dialog should appear:

Export matrix data as third party file format
The export matrix dialog. Select the file format and file name here.


Output file format

Before selecting an output file, select the data format you wish to use to save the matrix file. Hydromagic can store point cloud or DEM data in one of the following file formats:

Select the data file format
Select the preferred data format for the destination file.


Output file

First, you have to select the output format and the file name of the data file. After selecting the data file format, use the "Browse..." button to select the output folder and file name. When you have selected a file that already exists, the software will ask whether you want to overwrite this file.

Select the data file location
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.
