Research On Virescence And Forest Information Standardization In Shanghai And Related Software Development

With the continuous development of information technology, it has spread into various industries and areas. However, because the standardization in applicant field hasn't developed accordingly or in advance, there is a series of problems such as information and data sources are not unified, Data Storage format can't cope with, data structure unclearly, unable to share the data. These issues affect the applicant systems development related to data, it is therefore necessary to do Information Classification and Coding Standardization, clarifying information among structure and form a unified standard so that it can better share and exchange information. Shanghai virescence and forest data are collected for a long time without a unified standard, data acquisition are not unified, Data Storage is inconsistent, thus cause many inconvenience in data unified management. The development of information technology has provided new technologyIn information acquisition, processing and analysis of virescence and forest industry. And the standardization of information technology is important, only proceeds in accordance with the standards of information technology, can we achieve the sharing of information resources and give full play to the role of information technology. Standard First is an important experience both in and aroad.To achieve Shanghai virescen and forestry information standardization, we should summarize the existing domestic and international standards status, clarify the basis of standard making,confirm the standard rules in terms of the overall needs, organized and divided in scienfical way. Research results of this article and reads as followings :1. A summary of internal and external classification and coding standard setting, Discussed the basic princinples of the Green Forestry classification and coding standards. Combining the real situation of Shanghai Landscaping information management, identify the code classification standard and methods, to form a specific coding sheet and develope the sofware tools of information entitle coding.2. On the basis of information classification coding identification, explore the design standard of Shanghai virescence and forest cover Management Information System database design standards. Identify database design principles, methods, and form a complete database design table. During database designing process, design geographic information data base through UML and CASE tools by summing up the advantages of UML, and using Microsoft Visio as well to realize the creation of Shanghai Landscaping forestry database.3. Explore the methods of interprete and update Shanghai virescence and forest cover information through the use of remote sensing, and develop the area corretion index tool by considering the impact of several factors such as green coverage influenced by remote sensing image type, investiaged green type, buliding shadows,ect.4. In the area of data processing, identify the integration methods of Shanghai virescence and forest cover data, and set up the procedure of mixed both data. The development is guided by similarity, matching the virescence and forest cover data, and develop the software tools related.Shanghai virescence and forest cover information classification and coding methods, database design standards, information updating methods and data processing methods provide a basis for virescence and forest cover information standardization. In the future we can work to further explore the related standards, and improve data integration methods and software tools, making them more intelligent.
