Realization And Application Of Remote Sensing Interpretation Symbol Database Of The Mesozoic Volcanic Rocks In Greater Khingan Range

The interpretation of remote sensing image is important information obtained from the image,The interpretation of remote sensing images characteristics and interpretation signs should be taken into account in the interpretation.The image features are described in terms of spatial resolution,time resolution,radiation resolution and spectral resolution,remote sensing interpretation signs can display t he spectrum and space information in the image,color,cover geometry,shadow,size and texture,can explain the image features,and the relationship between the state of nature.According to the remote sensing image interpretation method,the interpretation mark is important,which is convenient for object classification and summary,is conducive to the management of scientific data,and lay the foundation for further on remote sensing imaging mechanism,has important research value in foundation for the interpretation of the mapping has great application value,enhance the accuracy and efficiency of drawing.Greater Khingan Range is a volcano rocks of Mesozoic tectonic belt in the northeast of China widely,especially in the late Jurassic volcano activity was very intense,a lot of volcano rocks constitute an important part of Greater Khingan Range magmatite belt in Greater Khingan Range,Mesozoic volcano rock and volcano mechanism features,based on the remote sensing image interpretation,so as to obtain the volcano rock research in the area of interpretation marks,had a very good application in vegetation coverage area.In this paper,we summarize and establish the image interpretation mark in the process of remote sensing geological interpretation and field verification.According to the analysis of the requirement of the interpretation mark database,the structure and function frame of the database were researched and designed,and the basic function of the interpretation symbol library was realized through the platform.The main research results were as follows:1.Study on the characteristics of the Mesozoic volcanic rocks in Greater Khingan Range.The demarcation line of the research area is mainly circular and quasi-stratified,it presents the typical development of the type,radial and annular drainage pattern,the eruptive phase,the overflow phase,the volcano channel facies volcanic facies have development,the relief of the topography is medium,according to the study area of landscape characteristics,regional geology,etc.combined with the field exploration,using visual interpretation,the paper summarizes the interpretation marks of color,morphology,water system,topography and pattern.Data preparation is made for the construction of interpretation tag library.2.The interpretation marks of the database according to the standard of frame structure design on the basis of the demand analysis,the design of knowledge organization structure library interpretation signs,make full use of advantages of both hardware environment,high efficiency,low cost,in order to construct a scientific and efficient interpretation bank important foundation.3.Based on the Microsoft platform of Visual Studio 2010,using Visual C# language as programming language,combined with Microsoft SQL Server 2008 database,using object oriented programming method to complete the Greater Khingan Range Mesozoic volcano rock interpretation symbol library,realizes the data management,image interpretation,water extraction and other functions,beautiful interface,easy to operate,reasonable structure,good stability,and has very good application effect.
