Enterprises as the mainstay, work to promote the industrialization of Earth observation, aerial remote sensing applications range from the original main auxiliary of the government's macro decision-making, to various fields like economic construction and social development; emphasis on multi-source image fusion among high spatial resolution, high spectral resolution and high time resolution images, information processing and services, has formed a more complete remote International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XL-7/W1, 3rd ISPRS IWIDF 2013, 20 -22 August 2013, Antu, Jilin Province, PR China sensing information industry chain; rapid rise in operating airborne remote sensing technology and its data supply companies in the United States and Europe, marked the commercialization and industrialization of aerial remote sensing, especially much develop under the support of government and military of these countries.

AVIATION REMOTE SENSING
The domestic aviation remote sensing technology, starting from the 1970s, after ten years of hard work, has developed into the practical. Overviews of China's aviation remote sensing industry, has experienced three developmental periods, as shown in Figure 1.

Introduced and popularized the concept period.
Remote Sensing basic theory, method and application test were promoted.

Technology growth stage.
With the development of remote sensing science and technology, the field of aerial remote sensing applications has been gradually expanded. Since the founding of state, the government invests a large-scale resource to environmental Investigation, because of the limit of earth observation technology and equipment, professional teams used aerial remote sensing means, accorded to uniform specifications and technology acquisition, processed and centralized storage, besides, information service agencies were responsible for the distribution and management of information.

Industrial growth stage.
Aerial remote sensing industry gradually developed with the process from nonexistence to existence and from small to large. National investment gradually increased with the development of remote sensing applications, especially in infrastructure construction. With the increase in national investment, the remote sensing market open further to increase the confidence in private capital, began to increase input; invest in the country reaches a certain climax, the exponential growth of private capital into the field changes aerospace remote sensing capital structure, private capital will reach more than the national investment, in the same time, state capital in the field of aerospace remote sensing will gradually reduce when the private capital market development further enhance and aerial remote sensing industry market capacity further increase. At present, China's aviation remote sensing industry is in a period of development of the third generation.

CHALLENGES FACING THE DEVELOPMENT OF THE DOMESTIC AVIATION REMOTE SENSING
Domestic aviation remote sensing has a long history and develops rapidly. More and more enterprises engaged in aerial remote sensing and aerial photography. Aerial remote sensing has become a better part of our field of geospatial information industry. However, due to the overall planning of the development of the domestic aviation remote sensing to coordinate management and market supervision is relatively weak, mechanisms for the sharing of information resources between sectors and regions has not yet been established. The low level of remote sensing information access and resource development and utilization of key technology capability of independent innovation, remote sensing applications, business and industrialization are existent problems. Mainly in:

Lack of top-level design and co-ordination.
A long time, water conservancy, mining, land, agriculture and other departments actively developed aerial remote sensing system to serve the industry, different departmentalized repeated acquisition and processing of images of the same area is also very prominent phenomenon. Remote sensing image processing standard of the departments are not unified, the lack of copyright protection and information sharing coordination mechanism, resulting in outcomes of single-use and sharing of information is difficult; airspace management system is not perfect, and remote sensing images confidentiality regulatory, resulting in the procedure of the declaration and approval of the flight plan is complexity, to some extent, restricted the application of aerial remote sensing system.

Lack of innovative spirit and ability.
Domestic aviation remote sensing field could not basically get rid of the development model of tracking and imitate. The development and manufacture of aerial remote sensing system tend to attach importance to the integration technology, ignore the basic technology, neglect professional flying platform, highprecision positioning and orientation system with stable platform, independent intellectual property rights measurement type camera and software system to adapt to light small airborne remote sensing. A lot of the core critical components and parts still rely on foreign procurement that blocked from abroad. This situation seriously restricts the development of China's aviation remote sensing technology.

Small, scattered, chaotic phenomena exist on the industry as a whole.
As the absence of the dominant ideology of the overall strategic research and industrial development, the domestic aviation remote sensing industry has the spontaneity and blindness. SMEs aerial remote sensing was the industry body. Nearly a thousand of firms were specialized in aerial remote sensing trade, small market size disorderly and vicious competition is brutal. As technology research and industrial development out of line, no more conscious of the technical division of labor and the main direction has formed. Because of the size and economic strength is relatively weak, investment is not strong International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XL-7/W1, 3rd ISPRS IWIDF 2013, 20 -22 August 2013, Antu, Jilin Province, PR China enough to affect the speed of technological development, lead to the industry lack of core competitiveness.
