59.5 Advantages and Disadvantages of the Technology
59.5.1 Advantages of the Technology
Due to the restriction of spatial database technology, 3D modeling software and
GIS software, the development of 3D GIS system has encountered a lot of difficulties,
for example, high professional knowledge requirements; modeling software
is hard to learn; complex modeling process; and poor spatial analyzing functions.
While SketchUp is a convenient [26], easy-to-use, yet powerful 3D modeling
software with free mass data resource in the Google Earth as a basis. Moreover,
ArcGIS has powerful spatial analyzing functions. So the method of ArcGIS
combined with Sketchup improved modeling efficiency and reduced the restriction
to the professionals, generally reduced the cost of the 3D modeling. Thus it is a
new bright spot in the 3D visualization realm in recent years, and has demonstrated
great prospect.
