3 . Webinar Details We will cover the Google Earth environment and its integration with MicroStation. This connectivity allows DGN and DWG models to be published (used as overlays) in the Google Earth environment. MicroStation provides data to the Google Earth application as KML (Keyhole Markup Language) files, which are an XML based data structure. A “shapefile” is a popular geospatial vector data format for GIS software. It is developed and regulated by Esri as a standard or open specification for data interoperability among Esri and other software products such as MicroStation. “Shapefiles” store geometric location and associated attribute information that can be read with the “Item Browser” within MicroStation V8i. A “shapefile” is actually a set of several files. Three files are Mandatory to store the core data: .shp — shape format; the feature geometry itself .shx — shape index format; a positional index of the feature geometry to allow seeking forwards and backwards quickly .dbf — attribute format; columns of attributes for each shape, in dBase IV format

4 April 8, 2017 Geo-Coordination Tools – let you specify the position of your design on the earth’s surface A geographic coordinate system (GCS) can be selected from MicroStation’s extensive library of predefined GCSs. Another way is to assign the GCS of an attached reference to the active model. You can also assign the GCS from a model in another design file to your current model, even if it is not attached as a reference. When a geographic coordinate system is assigned to a model, that coordinate system appears in the Auxiliary Coordinates dialog (ACS) © 2006 Bentley Systems, Incorporated 4

5 April 8, 2017 Item Browser The Items dialog is used to display the non-graphical items contained in a DGN file or a Shape file. Select File > Item Browser or use the icon on the Primary Toolbar. The Items dialog contains nodes representing the item types of the data in the file. The nodes group the items by type and when you expand them, you can see the individual items, or component instances, contained in the file. You can view items in a model by setting highlighting, zooming, isolation or transparency in the Items dialog. Tools are at the top of the dialog.

6 Google Earth and MicroStation
April 8, 2017 Google Earth and MicroStation You can export geometric data from MicroStation into Google Earth and have it geo-located. MicroStation provides data to the Google Earth application as KML (Keyhole Markup Language) files, which are an XML based data structure. MicroStation geometry exported to KML retains the reference and level structure that is defined in a model. First, in Google Earth, create a placemark at the required location and save it as a KML file, by right clicking the placemark and selecting Save As. Second, in the design, use the Define Placemark Monument tool to define a monument point that matches the location of the Google Earth placemark. Third, in the design, use the Export Google Earth (KML) File tool to export to a Google Earth KML or a KMZ file. © 2006 Bentley Systems, Incorporated 6
