requires us to understand construction classification criteria
correctly in the design. Next is to understand the local
architectural style, the natural conditions and social customs as
well as the religious belief in the surveyed area of various
countries and regions, then we can classify the construction
accurately.
5.6. The Problem of Topology Relation
When editing the captured data, often meet the following
problem: the topology relation is created incompletely, the 3D
data capture and the 2D capture present the chaotic
phenomenon. After merging the files, it presents the redundant
or overlapping phenomenon. But such problems can be solved
through checking repeatedly by running Siradel’s ARSC-
CHECK programme.
6. CONCLUSION
Since cooperating with Siradel France in 2004, ARSC has
produced DEM and DSM data for Hong Kong, London, New
York, Romanian entire boundary, and many French cities
including Paris. Moreover, it’s first time that we use IKONOS
stereo pair imagery to produce DEM and DSM data for
Morocco cities such as Rabat and Casablanca successfully.
ARSC provides the high grade DEM and DSM data that have
already obtained France side's complete approval, also made the
aerial photogrammetry method to generate DEM and DSM data
applied in the data production widely. During working in the
future, we will still make furtherer research for the approach to
generate the DEM and DSM data by using the aerial
photogrammetry method so that we can try to do better in
improving the production efficiency and quality.
