A Study Of Production Technology Of Protected Areas Thematic Maps Based On Remote Sensing Image

In recent years, the impact of the Brachymystax lenok tsinlingensis vandalism as well as the natural environment is very serious, in order to protect the Brachymystax lenok tsinlingensis and other rare animals, we need to clear the terrain and geography of protected areas, drawing a large scale and the strong current trend thematic maps. This paper discusses the method of extracting feature information creating thematic maps based on remote sensing images, and its advantage is not only readable, current situation is strong, but also contains a wealth of information, available on the landscape, such as a comprehensive geological interpretation, and make the non-professional user at a glance, to increase awareness of the map.Based on remote sensing images make protected areas thematic map process, this paper firstly combined protected areas examples of thematic map design has been studied and analyzed; Secondly thematic map compilation methods specific discussion, to lay the theoretical for the production of protected areas thematic maps. Finally, examples of protected areas to complete the preparation of Longxia n country of Shaanxi Province Brachymystax lenok tsinlingensis maps Nature Reserve, 1:2000 scale subdivision map and protected area of rare animal distribution, and production technology analysis and research. This paper mainly do the following work:(1) Describing the general method of thematic map design, with examples of protected areas thematic map analysis mathematical foundation design, sign design, illustration design and surface effects design;(2) Introduction of thematic maps prepared by the method that the basic method of remote sensing methods for the preparation of thematic maps and thematic maps prepared. Detailed basic principles and procedures for both the preparation methods, the theoretical basis for the production of thematic maps of protected areas.(3) Binding nature reserve Longxian country Brachymystax lenok tsinlinge nsis instance, the use of Arc GIS software to make remote sensing image as a base map of protected areas1:20000 scale map, 1:2000 scale subdivision plans and protected areas 1:50,000 rare animals distribution. Firstly, collection and preparation of protected areas thematic information; Secondly base map data analysis and processing of remote sensing images geometric correction; Finally in the production of thematic maps thematic map elements layered data processing, interpretation river and the surrounding elements, attributes data entry, design content, maps output.
