In the paper, after analysing the demand of the study on the global change and sustainable development of society, the becoming environment and application base of the geo-spatial information technology are presented. In accordance with the nature and mission of the new round of the survey for the land and resources, the paper discusses the application of the geo-spatial information technology to a new round of the survey for the land and resources.
This article simply discusses the situation of digital remote sensing techniques which has been applied to monitor the land use dynamic change, introduces the notion of land use dynamic monitoring by remote sensing, the methods and the steps. Now there are a few difficulties including the data preprocessing and the monitoring methods selection. It is necessary to enhance the study of the digital remote sensing techniques applied to resources and environment.
The paper introducs the current situation about application of artificial neural network(ANN) in Remote Sensing, sets forth basic principles、technique、advantages and operating method of ANN, and presents a case study which had been carried out by authors.
On the basis of the analysis to the water invasion accidents at Jiao Zuo mining area, the paper indicates that the immediate water source to the coal mine is L8 karst water and the unimmediate water source is the Ordoviccian karst underground water. So it is the key to verify the water invasion accidents lies in detection the recharge path and intake position of L8 karst water. Because the anomalies of surface thermal radiation is relation to the karst water (L8) movement, the airborne infrared data is a better method to detect the thermal anomalies, the cool anomalies and the study karst water movement further. Through interpretation of thermal infrared image of Yanma coal mine, two positions of water intake were discovered and have been confirmed.
According to the reflection characteristic of water body on solar radiation spectrum, the suspended silt distribution of coastal region in Fujian Province was analysed by using NOAA polar orbit satellite multi-channel spectra reflectivity remote sensing data, and so obtained a preliminary monitoring result from good quality maps of silt distribution in different time.
This paper applies the method of Linear Regression to study apparent reflection of the rocks and takes the Jing yue lake test place of remote sensing as an example.
During the comparing and slecting of the G320 Dali-Baoshan freeway, the author uses the remote sensing image for interpreting the topograph, the geomorphologic, the stratums and rock property, the geological structure and the geological disaster. By comparing the engineering geological conditions of three lines (the north line, the medium line and the south line), the author confirms that the medium line is the best than the others.
This paper, taking the Lingquan Basin for example, approaches the method of how to use the airborne γ spectrum data, the airborne magnetic data and the remote sensing data to distinguish the rock property. These methods are ①the method of using γ spectrum data and MSS data, by K-L change to extract the rock property information; ②the method of using γ spectrum and TM data, by IHS change to extract the rock peoperty information.
Sequential rock remote sensing information is a group of rocks which are related with each other in space or space and time. This paper uses optimum segmentation method to divide the sequential rocks of Seerteng mountain, Inner Mongolia Autonomous Region, and gets the good results. At the same time, the paper points out the advantages and disadvantages of this methods.
By using NOAA data, two methods for calculating the area of any things on the earth are provided. These methods can be used to account quickly and exactly, because they do not need to rectify the image. Finally, an example is giving.
This paper introduces a new technique of making remote sensing picture, which is the technique of light jet 5000RS, deals with its pinciple and mapping process, analyses the feature of the output pictures and evaluates the application results of this technique.
