Extracting 2d grid data from dfsu

Is it possible to extract a frame from a dfsu (area output) file and export it as a grid of values (ie. grid of current speeds)? I can load the dfsu into the grid editor but cannot see a way of exporting just one frame into an ascii grid file. Also, is it possible to do this in Matlab using the MIKE toolbox add-on?

Thanks

Hi kin.gyo,

You can create a *.dfs2 file from a *.dfsu file by creating a new "Grid series (.dfs3, .dfs2)" file. When creating this file, you can then select "from Dfsu file": this will allow you to convert your dfsu file into a dfs2 file. You can then convert this dfs2 file to ASCII by use of the following toolobox: MIKE Zero Toolbox \ GIS \ Mike2grd.

If you want to export only a part of the whole domain from your dfsu file: you can either crop the generated dfs2 file (in Tools \ Crop) or crop the dfsu file using the Data Extraction FM tool (New \ File \ Data Extraction FM).

I guess this answers your questions.
