© 2012 Bentley Systems, Incorporated 2 | Topics –Geocoordination –Georeferencing CAD data –Integration with GIS Reference Import Export –Promoting CAD data to GIS GIS for CAD and BIM users

© 2012 Bentley Systems, Incorporated 3 | Define a GCS for a DGN file Tools –> Geographic –> Select geographic coordinate system Select GCS from dialog and assign to DGN Only useful if DGN is in the correct geographic space Benefit –Easier GIS, Google Earth integration –Better interoperability in multi- GCS project

© 2012 Bentley Systems, Incorporated 4 | Georeferencing CAD data CAD data typically is referenced to a local coordinate system MicroStation has tools to create a local coordinate system that will convert to a geographic coordinate system Advantage –CAD data can take advantage of GIS data, Google Earth integration

© 2012 Bentley Systems, Incorporated 5 | Interoperability Many GIS sources –Oracle Spatial –SQL Server Spatial –Esri SHP –MapInfo MID/MIF, TAB –CSV –GML –WFS Benefit –Take advantage of data in many forms –Conversion not necessary in many cases

© 2012 Bentley Systems, Incorporated 6 | Promoting CAD to GIS Simple features can be promoted to intelligent GIS features easily –Using the Promote tool –Using Dynamic Feature Scoring Benefit –Easily incorporate CAD accurate data into GIS –No redigitizing
