Re-coordinating site drawings

Hello Ladies and Gentlemen, I have a 3D site survey possibly carried out using some provisional local controls. With clearly identifiable features of known global and local coordinates, is there a simpler way of re-align the site drawings in the global coordinate system without having to employ the Microstation modification tools?,

I am thinking of acs of the reference file.

Could the effect of such microstation modifications be propagated to other vertical packages like InRoads, Geopak etc? 

I would very much welcome video demonstrations if it is possible.

Many thanks in advance.

  • first you need to establish from ustn if there is a datum attributed to this file  the geographic tools  should tell you if your survey file has a datum registered to it  if mstn reports no datum assigned...

    then you need to find out what the datum that the surveyors used if you can determine that from them then using the geographic tools assign that known datum to the model...

    now obtain a similar area off features via any known datum via the internet....or coordinates of known features that should fit in your site survey ie psms etc...

    create a new empty file assign  a datum preferably a known common coordinate one not long lat but east/ northings

    now ref attach your original survey and let mstn  reproject it to the known active datum.. repeat with the known download ref file or circles by place points by coordinates via keyin xy= ,   ( where you enter the known E & N )

    these then should land on top of known objects like the psms....

  • Thank you Everyone. We all know the state of play know. I am however heartened by the pace of development at Bentley and of course this is pretty easy for our Ever Respected Development Team to incoporate into the next generations of MicroStation. MicroStation is increasingly becoming central to what Bentley is trying to achieve and it is important that a tool capable of resolving translation and rotation issues resides within Microstation.

    We are going to assist the development team with positive critisism.

    Well done Ladies and Gentlement. More discussion topics will follow shortly
