Reflections of The Teaching System of "Remote Sensing" Course
Reflect on the contents of "RS" teaching materials
The contents of " RS " teaching materials should include RS fundamental theory;
composing, classification, performance indexes of the RS technology system and
selective principles based on the observed object; acquisition, correction, error
processing, and quality control methods and application items of RS data, and the
basic requirements of information extracting for RS data; choosing and buying,
querying, storing of RS data; establishing the database and managing regulations and
the composing of market; the technology means and system of adjusting,
transforming and classi-fying of computer graphics and image, technical control of
RS application items and procedures, standards, specifications and quality guarantee
system of its specific implementation; the fields of RS application and the
requirements of characteristic; the combination and integration of RS, GIS, GPS,
computer cartography, network communication and other modern technology.
The fundamental theory of RS
The purpose of this section is to help students master the physical basis of RS,
know the sending, reflecting, radiating theory of electromagnetic waves, understand
the theory of radiation transferring and the atmospheric effect on the electromagnetic
waves' radiation transferring, learn to collect ground objects' spectrum and set up the
mathematical and physical relations between the standard spectrum data and the RS
information, and make clear the rules in setting and distinguishing the working wave
band of remote sensor and the basis of pursuant spectrum band of electromagnetic
waves.
The technology system of RS
This section should include the knowledge about aviation, aerospace, ground and
variant RS wave bands, and make students learn about the relationship among all
kinds of RS platforms, RS sensors, data transferring systems, data receiving systems,
data pretreatment systems, image & graphic processing systems and database
management systems and master the classi-fication and capability of different
platforms and RS sensors and related system and learn to select the relevant
technology system on the basis of the observed object.
The acquiring of " RS " data
This section should mainly solve how to record the electromagnetic waves that the
ground objects reflect or send on the optical or magnetic medium, and make students
learn about the performance, classification, and interrelation corresponding to
electromagnetic spectrum's characteristic of all kinds of media, understand the
principles deeply that RS can monitor objects, know the reason why different wave
bands differently reflect the same object, master the method of analyzing the effected
factors of RS data, learn geometry correction and spectrum correction of the RS data,
avoid errors and make the processed RS data meet the basic demands of information
extracting through quality control.
The choosing and buying and querying of " RS " data
To introduce the acquiring and marketing organization of Chinese aeronautic &
aerospace RS data and the methods and rules of RS data management, make students
choose and buy the satisfying RS data through technical market. Moreover, students
should master the record format of all kinds of data, the means of discerning the data
quality and the indices of data checking and accepting, and make clear the problems
which should be considered when choosing and buying the relevant RS data on the
basis of the undertook item.
Computer graphic & image processing
Since has become an important approach of RS information extraction, this
section must be strengthened. However, based on the regulations of relevant curricula
in colleges, this section can't be replaced with the specialized. Therefore, the problem
of correction, conversion, and classi-fication of RS data through technique should be
solved emphatically in RS teaching materials, and become the deepening of the
specialized courses of computer graphic & image processing in application. The
teaching should make students understand how to correct the RS data accurately, how
to design the corresponding method of calculation, how to enhance the data, how to
stress the extracted information, and how to grasp the significance of computer
graphic & image processing deeply through processing the specific standard data.
Technical control of applied items of " RS "
This section should involve the control principals, methods, and economic results of
all applied items in the whole process which include analysis for demand, technical
design, the selection and of specifications and norms, the establishment of quality
guarantee system, and the specific implementation. Students should learn to analyze
the technical feasibility of specific items, make clear the problems, which can be
solved by researching RS for specific items, and the preset precision so as to master
better the application of RS in technical serving.
Applied fields of " RS "
Because Applied fields of " RS " are very wide, and can't be narrated overall, this
section should be classified according to resource, environment, anti-catastrophe or all
kinds of specialized RS, introduce the successful cases and typical items, and make
students come into direct contact with the practical work.
