Someone needs a local coordinate system for a special project, and then useGeo Coordinates to place the building in an official coordinate system.
Is that possible, and how does one create the local system so that itcan be translated?
Use Google Earth PlacemarksIn MicroStation V8i one can construct a Geographic Coordinate System(GCS) from Google Earth placemarks. See What's New? > New in MicroStation V8i > Geographic Coordinate System support in the help file for an introduction.To use placemarks you need to know the latitude and longitude for anumber of points in your design. Be aware that you use enough decimalsfor these values. Depending on the latitude, one degree may be over ahundred kilometers and you'll need 6 or 7 decimal places for centimeteraccuracy. You'll need at least two placemarks to define a coordinatesystem.First you need to define your placemarks using the "Define PlacemarkMonument" tool from the Geographic toolbox. Using these placemarks youcan define a coordinate system with the "Select Geographic CoordinateSystem" tool from the same toolbox using the "From Placemarks" method.More information about these tools is in the help, under Working WithComplete Designs > Geo-Coordination > Geo-Coordination and GeographicSystem Support > Geographic toolbox.
