基于MAPGIS的遥感特征线分析方法设计

对遥感图像进行地质解译，获得的特征线图，是基础地学研究和矿产预测的有利工具。为弥补人的视觉识别特征线的局限性，需用对这些特征线进行进一步的定量分析、解译，获取更多的地质信息。作者在本文中通过计算构造复杂度量，划分出受构造线影响地区的不同构造复杂度。在此基础上，用ＶＣ＋＋在ＭＡＰＧＩＳ开发平台上，开发了遥感特征线分析系统。该系统对特征线图进行了定量化的划分，划分后的构造复杂度分布图可与物探、化探数据

DESIGN OF ANALYSIS METHOD ON LIENMENTS BESED ON MAPGIS

Lineament maps derived from the remote sensing image by geological interpretation are useful tools for basic geological study and mineral prognoses .In order to make up the limitation of eyes while recognizing lineaments, we need to calculate and analyze lineaments deeply. In this paper using the Structure Complexitv, we describe the different structure complexity influenced by the lineaments. On the basis of this method, an analyzing system for remote sensing lineaments is developed on the developing platform of MAPGIS using visual VC . By using this system we can partition the lineament map quantitatively. The result map can be combined with geophysical-geochemical digital map and to extract the geo-anomaly region further.
