4. APPLICATIONS
4.1 Photogrammetry
With the research, development and generalization of the
digital photogrammmetry in depth and in strength by the end of
the last century, Digital Photogrammetry Workstations (DPWs)
have been popularized in China. At present, aside from few
analytic plotters in large-scale mapping, most photogrammetry
projects are preformed by DPWs. Furthermore, more and more
private companies and enterprises enter into these fields, other
than the traditional organizations such as some province
bureaus of surveying and mapping, some investigating and
designing bodies in different ministries and commissions.
Some large photogrammetry organizations, for example,
Sichuan Bureaus of Surveying and Mapping, Shannxi Bureaus
of Surveying and Mapping, and Heilongjiang Bureaus of
Surveying and Mapping, could provide some services for
oversea projects (USA, Japan, and some European countries).
Therefore, it is the rapid development period of digital
photogrammetry from 2000 to 2004 in China.
4.2 Close Range Photogrammetry
There are many examples in application of Close range
photogrammetry in different fields other than traditional ones.
These successful templates are finished by various kinds of
sectors, such as China Institute of Geotechnical Investigation
and Surveying, Donghuang Research Institute, Wuhan
University, Zhongshui Northern Company and Zhengzhou
University of Information Engineering. Based on Close Range
photgrammetry and 3-D Laser scanning technologies, some
applications are involved in surveying and virtual reality
wandering of the ancient sites and cultural relics as the Imperial
Palace in Beijing, Mocao Caves in Dunhuang, Mausoleum of
the First Qin Emperor and Terra-Cotta Warriors in Xi’an,
Three Gorges Project Submerged Area, Linshan Figure of
Buddy in Wuxi, Budala Palace in Tibet, the Figure of Buddy in
Leshan, the Rock Cave in Yungan, etc. The close range
photgrammetry technology is also been used in athletic training
in the Sports Research Institute of General Administration of
Sports. Other applications include hydroelectric project
constructing, hydraulic model monitoring, buccal 3-D model
establishing, debris flow monitoring, and hydraulic building
distortion monitoring etc. The 3-D CCD camera will be
249
mounted on the Chinese moon-probing satellite. Shandong
University of Science and Technology implemented the low-
altitude photogrammetry test based on Hasselblad 555 ELD
camera mounted on helicopter. Moreover, they also experiment
the micro-photgrammetry of the steel-carbon fracture by
electron microscope.
4.3 Remote Sensing
In the area of resource investigation, satellite images have
become the primary information sources in China. The
application of remote sensing in land resource has widely been
adopted by cities and towns and photogrammetry and remote
sensing play an important role in these applications. High-
resolution images application is highly regarded than ever.
When it concerns to key projects in China, such as “South to
North Water Transfer Project”, “West to East Power Transfer
Project", * West to East Gas Transfer Project”, “Qingzang
Railway", "Three Gorges Project", and some projects for
"Digital City"and “Digital River”, photogrammetry and remote
sensing provide spatial information and have been the technical
guarantee in engineering plan, design and implementation. In
the areas of environment protection and change detection,
photogrammetry and remote sensing technologies provide new
methods and approaches to support the researches in
atmosphere environment, water environment and ecosystem
environment. The application of middle and low-resolution
satellite data has gone more and more far and come into being
hotspot. For the purpose of disaster monitoring, such as that for
fire, drought and flood, photogrammetry and remote sensing
technologies have been widely used in disaster’s prediction,
monitoring, and mitigation. After HY-1A being launched into
space, the application of remote sensing in ocean has being to
the top. Lots of applications have been carried out in the area of
sea ice, red tide, coast zone and the corresponding application
template systems have also been developed. With the
combination of Electromagnetic remote sensing and sonar
remote sensing, 3-D observation for ocean has been formed
gradually. The applications in microwave remote sensing
become more widely feasible than before, such as in flood
monitoring, mine resource investigation, soil erosion analysis,
rice planting areas and ocean wave elevation analysis and so
on. All of these show that the applications of microwave
remote sensing are being on the way to more fields.
