59.5.2 Disadvantages of the Technology
Although ArcGIS combined with SketchUp technology has many advantages, but
as a 3D modeling approach, it also has some inadequacies.
For example, this method is relatively limited in space [19]. If the scope of the
visualization is too large, the operational speed will be greatly reduced; at the same
time, the precision of the 3D models are subject to the restriction of the operational
efficiency. The higher the detail degree, the lower operating efficiency [19]; And
when imported into ArcSence software, the SketchUp model often produces distortion
[27] using the noninherent material; Furthermore, due to the SketchUp
software lacking some advanced features like some other professional modeling
software [27], the computer runs slowly when the amount of data increases; Though
MutiPatch type can store some data, the efficiency is relatively low. So the storage
and fast processing [28] of the 3D multivariate data is a problem; So currently, due to
the restriction of the development technology and database technology, the spatial
analyzing function [28] of the 3D visualization system is poor; moreover, because
3D data obtained in real time will waste a lot of time and manpower, the low-cost
access of 3D data is a problem [28] in 3D visualization; and last but not least, the
popularity of the 3D visualization is limited by the broadband penetration [19].
Though, the technology has such inadequacies, but as a new way of 3D modeling,
it also is applied in many fields and guides the development direction of 3D GIS.
