秭归县土地规划制图的数字图像处理技求

PROCESSING TECHNIQUE ON NUMERIAL IMAGE CLASSFICATION MAPPING IN LAND USE PLANNING OF ZIQUI COUNTY IN HUBEI PROVINCE

1987年以秭归县为研究区域,并以该县归州镇和水田坝作重点剖析,应用彩红外航片判读制图,完成了秭归县四种基本图件。还采用薄膜图多信息套合综合分析,编制出秭归县1/5万林果草规划图。其制图技术能准确定位、定性和定量;体现了科学性、生产性和可行性;在成图上能自动分类、自动量算和自动制图,达到了较高的技术要求;探索了规划制图的数字图像分类处理技术,

The processing technique was carried out at at Quizhonzhen and Shuitianba sites based on chromainfrared aerial photo interpretation associated multinformation transcript with plastic map, a 1: 50000 scale land use planning map of Ziqui county was draw after a comprehensive analysis. Combinative informations and special planning index elements were used instead of the ordinary method of supervised and unsupervised classification, by which a correct physical and mathematical moulds were established. Chromatic classification images and its areas were obtained after a series logic calculation, and the chromatic land use planning map was draw. The processing technique to be sure in land use planning mapping with accuracy, quantication and automatic operation.
