- 摘要：Based on the spatial character of environmental variables and their relationship to land rating the authors have developed a automated method of urban land rating. The method first analyses the procedures of land rating in applying GIS, and then presents a set of spatial analysis models for the derivation of rating values. These models consisted essentially of spatial interpretation, digital terrain model, buffer and overlay analysis. The study revealed that the key technique of automated method is to establish a practical and efficient information system of urban land rating under the penetrating analysis of "Rules of Urban Land Rating" and the main steps of establishing this system are to manage the rating factors and design the analysis models.

发布时间：2021-06-10 - 摘要：This paper centers on development and calibration of winter wheat yield remote sensing model. After analysing the requirement of necessity for wheat growth such as sun light, temperature, water and fertilizer, we developed a winter wheat yield remote sensing model for large area based bn vegetation index,temperature change rate, greenness change rate, etc. To meet the requirement of operational system for estimating winter wheat production of large area using remotely sensed information, we developed several novel techniques in variable acquirement and model calibration.

发布时间：2021-06-10 - 摘要：Based on several snow cover data from interpretation of OSL visible waveband images and weather station records in western China for 1978/1987, the equation of snow depth retrieval algorithm in view of the difference of SMMR brightness temperature between 18GHz and 37GHz has been evaluated and adjusted in this paper. According to DEM data the whole western China has been divided into five physiographic regions by means of GIS: high mountains, plateau, low mountains, rolling hills and basin. The regional adjusting equations of the retrieval algorithm for these five units have been gotten separately and they have been used to calculate the mean conditions and interannual dynamic changes of snow cover extent and volume for 1978/1987. The results provide the important basic data for studying the effects of snow cover in western China on East Asia climate.

发布时间：2021-06-10 - 摘要：Based on the landsat TM image data and the ground truth, the interpretation method is developed in this paper. In the case of Xiaojiahu Region, the image of flooding period is interpreted. The inundated area is estimated by supervised and unsupervised classification; the distribution map of crop damage content is made in terms of RVI; the crop losses are estimated from the calculation of NDVI; and the results are discussed in detial.

发布时间：2021-06-10 - 摘要：This paper presents the marks for recognizing the buried faults in loess region, and the four types of buried faults have been classified: 1. bed rock faults 2. new structure or inheritance structure 3. dyke-rock or dyke swarm 4. deep structure. Based on above classification, the regional structure pattern and the third grade structure unit, which are different from the traditional concepts, have been proposed. According to the types of oil-gas reserve theory and the structural background in study region, it is suggested that the water-resisting structure entrap oil-gas reserve as oil-controlling structure. Then the three buried faults are taken as examples to explain the features of R. S. information of water-resisting structure or water permeability structure and their forming mechanism. At last, the three oilfields have been predicted in the work region.

发布时间：2021-06-10 - 摘要：This paper introduces the application of NOAA/AVHRR image data on oil & gas exploration in Jianghan Basin. The color composite image of band 5（R）, band 2（G）, and band 1（B） indicates the macrotectonics of the Basin clearly. From the unsupervising processing image of band 1, band 2 and band 4（32 types） the source rocks areas of the basin are defined. In the unsupervising processing image of band 1, band 2 and band 5（32 types）, three fundamental structures are interpreted, which control the oil & gas distribution. The mappimg of the Apparent Thermal Inertia （ATI） indicates that the oil & gas riching areas are mainly distributed between the biggest and smallest ATI areas.

发布时间：2021-06-10 - 摘要：In this paper, we describe an image compression technique that incorporates Peano scan with a fractal-based coding scheme. 1/10 compression rate is achieved. The reconstructed image remains high picture quality and retains original geographic characteristics. We use NOAA image in Jiangsu coastal area as an example.This scheme can not only be used in remote sensing image processing, but also has wide application prospect in medicine science, arts, communication, and computer science.

发布时间：2021-06-10 - 摘要：This paper presents a method of computation of ground albedo for satellite image pixel with a few scarely distributed ground data based on radiance correction of remotely sensed data. Firstly, a number of known ground data, including atmospheric transmittance, path radiance component of the value of remote sensed data and ground horizontal radiance for each pixel are used. Then, terrain effect on remote sensing value of each pixel is corrected with DTM. Last, inverse computation of ground albedo is conducted with the corrected data.
