2012 Bentley Systems Incorporated CADD Geocoordination GIS Keith

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

• 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 3 | WWW. BENTLEY. COM © 2012 Bentley Systems, Incorporated Define a GCS for a DGN file

• CAD data typically is referenced to a local coordinate system • Micro. Station 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 4 | WWW. BENTLEY. COM © 2012 Bentley Systems, Incorporated Georeferencing CAD data

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

• 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 6 | WWW. BENTLEY. COM © 2012 Bentley Systems, Incorporated Promoting CAD to GIS
