Land Resources

The superiorities of the satellite remote sensing (RS) technology lie in the macroscopic view, dynamic monitoring, convenient access to information, intuitive images and large-coverage ability. The extensive utilization of high-resolution satellite images in land resources investigation has begun to gain its social-economic benefits. Satellite RS Imagery data plays an increasingly important role in land resources management, by which we can make timely, accurate and efficient estimations about the current land utilization.

Significant Application Value

Rational and reasonable exploitation of natural resources is vital for achieving the goal of sustainable development. The most crucial resources for our human being’s living and development include land, forest, waters, wetlands, etc.  While they are changing constantly under the influence of human activities, it costs the traditional survey large quantities of human power and resources. Given the disadvantages of incorrect and inconsistent data and statistics, they are not able to meet the present needs of territorial resources investigation.

Advantages

The Changguang Satellite Technology has significant advantages in land and resources investigation by offering plentiful qualified and precise RS images collected by Jilin-1 constellation.

1.10 stably running satellites in orbit, with reinforced data collecting.

2.Up to 0.72m resolution images provide more detailed ground truth.

3.The ability and agility to collect data twice per day leads to the maximized efficiency.

 

Prospects

Satellite RS has become an indispensable means in land and resources investigation, evaluation, planning, management and reasonable utilization, acting as a backbone in certain fields. Jilin-1 constellation has provided products and services in a wide range of fields including land surveying and mapping, dynamic monitoring of land utilization, hot area monitoring, wetland resources survey and scored remarkable achievements.

Land Mapping

The RS technology can be applied in modern land survey. It classifies and files various information to provide scientific basis for land resources development and utilization.

 

Dynamic Monitoring of Land Utilization

Periodical RS imagery can be used to observe the land utilization situation. By overlapped analyses of the periodical images, changes of ground truth in the monitoring area can be detected and monitored. .

Hotspots Monitoring

With the employment of multiple high-resolution RS data, the land utilization information as well as farmland protection and urban evolution could be interpreted from a microscopic view.

Wetland Resources Investigation

A piece of wetland is not only an important natural resources, a unique ecosystem, but also a vital part of the global ecological environment. Due to the difficulty of establishing a global ground observing network, RS data became more important in wetland researches. It provides opportunities for promoting the wetland classification and distribution studies.

 

The standard optical static image is a standard sub-meter product collected by Jilin-1 constellation, which is corrected and calibrated by radiation and sensors. RPC models and metadata files are available in the general tiff format.
A standard video imagery is a standard video acquired by Jilin-1 constellation, which has a resolution less than 0.9m after being processed through image stabilizing and framing. Products in both avi and mov data formats are provided.
