Save view/fence to geo tiff

Hi

Is there a way to save the view (MicroStation v8i) or fence as geotiff or as tiff with a worldfile? I guess there has to be a way... but so far I couldn't find it.

(Reason: create a nice 'view' within a DGN file and perhaps several referenced DGN files and export this specific view (for example defined by a fence) to a georeferenced tiff file which will be imported to a GIS)

Hope you know more than me! Thanks

  • most gis packages can import DGN ..

    set a datum via geotools

    Then just fence file  your data ie place fence  then keyin FF= <file name you want it to be>

    then data point inside fence to confirm... Better that geotiff

    I used to import and export dgn to Mapinfo all the time via the Universal Translator in MapInfo...

  • @ Jason: Thanks, but I don't have Descartes. Do I guess right that the resolution would not be too good as it works more or less like 'print screen'?

    @ Lorys: Sounds not too bad. I thought the easiest way would be a raster with an accurant resolution but perhaps a (nicely arranged) DGN would be ok as well. Is there a downside as well? I am a bit blockhead at the moment: If I would convert this created DGN to a shapefile - would I get one or several (each per geometry type) SHP files? (I don't have a GIS in front of me an cannot install one as I am not the administrator.... -> can't test it personaly now)

    In printing you can create a PDF file.  In Print set Print Driver to be “Bentley driver” and click on the magnifying glass and select the pdf.pltcfg driver.  Do File > “Edit Printer Driver Configuration.”  Under Driver Properties set “Enable Georeferencing” to “On.”  This will create a PDF file that is Georeferenced.

    You can select the “tiff.pltcfg”  or the “jpeg.pltcfg” drivers, but they do not have the Georeference option in “Edit Printer Driver Configuration.”  

    making a pdf this way the pdf is in LONG LAT WGS84 when you open the pdf in acrobat reader...
    does the dgn have to be in that format to or does the pdf creation calculate the transformation from the DGN in utm to WGS84?

  • Hi Lorys,

    The GCS put in the PDF is the GCS of the model, which is what you should see if you attach the PDF in Raster Manager.

    By default Acrobat Reader displays the coordinate in lat/long.  

    Thanks,

  • that still doesnt answer clearly

    my dgn gcs in MGA 94/55 I pdf out to geopdf

    I open the pdf in arobat and its in Long Lat WGS 84 but is rightly transformed when I give the pdf to other party they maynot use mstn

    How can I be sure its correctly transformed... or does it need to be in long lat first in GCS before print to geo pdf...

  • Hi Lorys,

    Well correctly interpreting GCS information as well as doing the correct transformation is often prone to error. Since once the georeferenced pdf is created Bentley cannot assure that Acrobat will do the right thing there is no way to be 100% sure.

    So if you want to be sure you can always :

    - Attach your DGN to a WGS 84 model.

    - Reproject your DGN to the WGS 84 model.

    - Create the PDF from the WGS 84 model.

    Thanks,

    Mathieu



  • Thats what I do now but I was curious if microstation > geopdf did it for me in one step.
