ArcGIS/SketchUp Integration Background
As the SketchUp product and users evolved to include terrain and world
coordinates, importers were provided for Google Earth, GIS, and CAD. In 2005,
a SketchUp 5 shape file importer was introduced, and in July 2007, an ArcGIS
plug-in was released for SketchUp 6, enabling the import of selected point,
line, and polygon features, and for Triangular Irregular Networks (TINs) and
rasters. ArcGIS 3D Analyst/ArcScene can display SketchUp models as a 3D
marker symbol for a point. The next version of the plug-in (not released yet)
should contain a working SketchUp to ArcGIS multipatch exporter. An excel-
lent set of tutorials is available on the Harvard Design School website (Cote,
2007) that demonstrates how to create a 3D model using data from ArcGIS.
New Approaches
A generic tool such as SketchUp combined with GIS has significant poten-
tial for conceptual modeling of the surface and subsurface of the earth and
complements existing 3D geological modeling software. Prior to this thesis,
the application of SketchUp with GIS to geological modeling had yet to be
investigated.
Should creating 3D models be the role of the specialist? Since the 1990s,
computerized 3D modeling of the earth has become a critical part of
