2.1 Objectives
The main objective is to work with available numerical
cartography in order to permit spatial analysis in GIS
environments and dissemination with web technology.
A workflow is given to describe how is possible to obtain outdoor
modeling results using available software such as Google
SketchUp, AutoCAD and standard like CityGML.
Cad files and shapefiles are imported in Google SketchUp and
used as primitives to build a 3D environment that is finally
exported into a 3D city model (CityGML LOD1/LOD2).
The built 3D GIS allows to explore and query the 3D model and,
more important, run further spatial analysis.
