2.2 Close Range Photogrammetry Systems 
The Photographic Total Station constructed by Wuhan 
University, based on short base line series image technology, 
can be used to survey the earthwork and the coal stack. We also 
construct a system based on approximate-2D control field to 
establish the model for calibrating the digital camera distortion 
in School of Remote Sensing and Information Engineering, 
Wuhan University. Wuhan Hengke Cyber-tech Company 
developed the Solid 3-D Visualization System with 2 CCD 
cameras and a Im length fix-up baseline. Wuhan University 
teamed up with South Korea developed a vehicle-borne MM 
system for highway road network generation and surface 
quality detection and this system had been exported to South 
Korea in 2002, and its software had been sold to Italy in 2003. 
Wuhan University cooperated with Shandong University of 
Science and Technology developed a vehicle-borne system 
with 2 GPS receivers, 2-D Laser Scanner, CCD camera and 
control computer, for acquiring the city building vertical 
surface images. China Academy of Surveying and Mapping 
Science constructed a Data Acquisition System for Digital City 
based on low altitude unmanned aerial vehicle (UAV). 
2.3 Remote Sensing Systems 
In recent years, China keeps developing at a rapid pace in 
remote sensing platforms and sensors. Different series satellites 
have been launched since 2000, especially the success first 
manned space flight in 2003: 
€ Small satellite Qinghua-1 in 2000.06; 
€ Geostationary climate satellite FY-2B in 2000.06; 
€ Oceanic stellite HY-1A with polor climate satellite FY- 
1D in 2002.05; 
€ Earth resource satellite CBERS-02 and Probe -1 in 
2003.10; 
€  Spacecrafts SZ-3, 4, 5 since 2002.3; 
We are now developing our RADAR satellites. As to remote 
sensing sensors, there are some achievements should be noted: 
CMODIS in SZ-series, the second moderate resolution imaging 
spectroradiometer after USA; Multi-mode microwave sensor in 
SZ-4; 10 bands COCTS and 4 bands CCD camera in HY -1A. 
In Airborne remote sensing, we have capabilities to acquire and 
transmit multi-source digital data in real time, which have high 
spectral resolution, high spatial resolution and 3-D imaging and 
247 
round the clock characteristics. The airborne sensors we 
developed include: OMIS (128 bands), PHI (144 bands), MAIS 
(72 bands), and airborne SAR. The first remote sensing satellite 
calibration field in China was in operation in 2002.10. This 
means we have gotten a great progress in enhancing the 
calibration and validation of remote sensing data that will 
improve data quality quantitatively. We have cooperated with 
the White Sands Field in USA and Toulouse Field in France. 
China-made softwares of remote sensing processing and 
analysis are in developing. We believe there will be some 
powerful Chinese remote sensing softwares in near future. 
2.4 GIS Systems 
China has developed copyright-owned GIS softwares since the 
beginning of 1990s. At present, there are some representative 
national commercial GIS software, for example, GeoStar, 
MapGIS, and SuperMap etc. These softwares occupy more and 
more market share than before. 
3. THEORIES AND METHODS 
3.1 Photogrammetry 
With the continuous expanding and developing of digital 
photogrammetry, its theories and methods are also rapid in 
evolution. These theories and methods are also applied in map 
updating, close range photogrametry and industry surveying. 
Some progress are listed below: 
€ With the powerful capability of corresponding points 
matching in VirtuoZo, a rapid AAT module along with 
PATB has been constructed and sold more than 200 
: suites; 
€ We have extended the matching module in VirtuoZo to 
carry out the data fusion, with higher speed and more 
precision, among multi-scale remote sensing data such as 
SPOT and TM; 
e We have successfully accomplished the matching 
between DLG (road and water system) and remote 
sensing image. It would accelerate the procedure of 1: 50, 
000 map updating by using SPOT data; 
€ Prof. Zuxun ZHANG put forward a new theory, named as 
Generalized Point based Photogrammetry. This theory 
has been successfully applied in surveying the round or
