    I had a finally problem with my ras project. I would be greatful if you could help me.
    I want to display the depth of 2d flow to a real map. I am trying to open a new web imagery layer but unfortunately i cannot make it.
    I set the projection to ras mapper but when i open web imagery layer seems to be a problem and when a place the mouse over the file there is this message : “Error loading image from file C:/…./tif does not exist in the file system and is not recognised as a supported dataset name”…
    Could you please help me?

    Aditionally can i export the deth or velocity of 2d flow as layer in Arc or Qgis. Because i have a jp2 file of the project area and can see the result in gis programme.

    Yes you can export the depth to a raster (tif format) and display it in GIS. The user’s manual explains how to do this.

    What type of web imagery are you trying to open? Are you using a standard projection file or something else?

    I struggled with this a lot.
    I found that setting the projection makes a difference. I was not able to display any web maps until I set the projection to World_Mercator. Like this arc projection file:

    PROJCS[“World_Mercator”,GEOGCS[“GCS_WGS_1984”,DATUM[“D_WGS_1984”,SPHEROID[“WGS_1984”,6378137,298.257223563]],PRIMEM[“Greenwich”,0],UNIT[“Degree”,0.017453292519943295]],PROJECTION[“Mercator”],PARAMETER[“False_Easting”,0],PARAMETER[“False_Northing”,0],PARAMETER[“Central_Meridian”,0],PARAMETER[“Standard_Parallel_1”,0],UNIT[“Meter”,1]]
