    Hi everyone. i just exported D*V map and got the .tif files along with a .vrt file.

    I can not seem to import these in to autocad. Is there anyone who were able to successfully import D*V map in to cad?

    Hi,
    It is a single band raster storing the value of V*D. I can’t remember
    trying to load a single band raster into AutoCAD, but even if it works it
    might just look all black or all white. You will want to control the
    styling, probably using colour, perhaps to mimic how it looks in HEC-RAS.

    I guess if by “AutoCAD” you mean Map3D then that can do it. But if you mean
    normal AutoCAD you will need to style it in you favourite desktop GIS (I
    recommend QGIS) and export a rendered image.

    If you style it in QGIS, just do “Layer>Save As”, select “Rendered image”
    and save as tiff or jpeg.
    If you save as tiff, make sure to add a create option called “TFW”, with
    value “YES”.
    Once you have loaded the image into AutoCAD you can use the freeware
    utility called georefimg, which reads the worldfile and moves the image to
    the correct location and scale.

    Regards.
