Re: [MI-L] MI linework digitised from underlying raster becoming skewed when raster is closed

[Lars I. Nielsen (GisPro)]

Hi Ian, You always need to make absolutely sure, that the coordinate system (projection) of the vector table used for digitizing is identical to the underlying raster's. Especially if NonEarth is involved. Contrary to the belief of many users, it is very possible to mix Earth and NonEarth tables in MIPro, which very well could yield the weird result you experience. What you need to do her-and-now, is save a copy of your vector table in a NonEarth projection similar to the projection used by the raster image. Best regards / Med venlig hilsen Lars I.
