9. A SEAMLESS GIS/GOOGLE WORKFLOW
3D Buildings
• Using Sketch Up to build the building model
• Save the file with KMZ format (tour video will be zipped in the final KMZ file)
• If you still want to use 3D Warehouse to save loading time, save the placemarks, tours,
page info, and polygons in a kml file. But remember to check each placemark with the
model you already upload to 3D Warehouse.
3D Terrian
• Using ArcGIS Scene to create a TIN on a topo layer. (import the base .shp contour file
first)
• Import the imaginary file (e.g. an old map), make show the two layers are on the same
scale and hopefully the exact same matching top-down location
• Drape the new layer by right click on PropertiesàBase Height Tabàobtain height info
from the TINàApplyàPreviewàOKàExport Scene in 3Dà”Hello, Earth!” VRML 3D
