Abstract
With the rapid development of Information Technology and spatial technology, especially the advent of future "Digital Earth" era, based upon cultivating applied person with ability on RS techniques, considering that the RS teaching materials presently used in higher academy is over-theoretic and its engineering extent is too small, we try on discussing the "Remote Sensing" curriculum teaching system, including RS teaching materials’ content, teaching link and practice from the point of view of engineering of RS techniques, and bringing forward a design for " Remote Sensing " curriculum teaching reform in colleges and universities.

Introduction
With the rapid development of information technology and spatial technology, especially the advent of future " Digital Earth " era, RS techniques' status in the building up of national economy and national defense becomes more and more important, and its applied range gets more and more wide. And yet RS techniques must walk out of scientific laboratory , become applied technology and bring its predominance into play. For the application in geo-science, the key of engineering of RS techniques lies in the information extract that must be qualitatively exact and reach enough quantitative precision, and the transforming of production into specified data format.

To meet the demand of the development and application of, Cultivating applied person with ability is vital besides the essential work in aspects of fundamental theory, skill manipulation, operation specification and quality standard. Considering that the RS teaching materials presently used is over theoretic and its engineering extent is too small, we try on discussing the "Remote Sensing" curriculum teaching system, including RS teaching materials' content, teaching link and practice from the point of view of engineering, and bringing forward a design for " Remote Sensing " curriculum teaching reform in higher academy.

Analysis for current teaching system and RS techniques development's demand for persons with ability

Analysis for current teaching system
The RS teaching materials currently used in higher academy was compiled on the basis that Photogrammetry only pays attention to utilize the image geometrical positioning information, in the context of beginning to use the spectrum information of images, identify all kinds of resource and environment objects and visual interpretation as a basic technique approach and the weak computer graphics and image processing, and in the era when Digital concepts was not put forward yet. At that time, RS techniques was at scientific experiment stage, its application to practical engineering went on in the exploring view, precision evaluation adopted statistical means, there was no general norms and specifications, and standard land object spectrum database was not established. Therefore, teaching goal is/aims to make students realize the fundamental position of RS, RS technique system, and land object spectrum in the RS information extracting and understand the possibility of RS’ application in resource, environment and anti-catastrophe fields, and introduce the technological process of RS technical application, the train of thought of visual interpretation and so on. This kind of teaching materials have been published for more than 20 years since the seventieth of this century and played a great role in Chinese higher education. Despite much modification or reform with the development of technology, these teaching materials is not still adaptive to technology development and its requirements for persons with ability.

Analysis for RS techniques development's demand for persons with ability
It is well known that today’ world will go into digital era. American government put forward the development strategy of " Digital Earth ", which has greatly promoted the development and application of RS techniques. The development of Geo-science applied technology-GIS.GPS and other associated techniques radically changed the technical approach and route of RS techniques’ popularizing. So cultivation goal and corresponding teaching system of colleges and universities also should take changes following this from the point of view of demand for persons with ability and engineering. First, the persons with ability cultivated must grasp RS fundamental theory, and be able to build the mathematical and physical the land object spectrum and RS information spectrum of studied object and design the interpretation means and technological process of RS images; secondly, they should be acquainted with the relationship between the land resolution and sensor resolution of studied object; thirdly they should be able to apply the techniques such as computer graphics and image processing and computer cartography proficiently, build the relation among RS , GIS, and GPS, and handle RS information exactly using modern techniques; at the same time, they also should possess the abilities of researching and drawing the corresponding technique specifications and give a suggestion to technology standard. However, the current syllabus have no such demand.
