基于规则集构建的工程材料提取系统设计实现

为了解决工程材料人工调查难以获取和运输成本较高的问题,基于遥感图像地物识别和规则集的面向对象分类方法,实现了针对目标工程材料创建特征规则集以进行识别提取和对提取结果修正及相关统计的工程材料提取系统。该系统包含了数据的加载和导出,遥感影像分割,工程材料规则集的创建、存储和管理,工程材料提取,监督分类,提取结果统计分析和专题制图等功能。不仅为工程材料的获取提供技术支撑,提升了工程规划前期目标工程材料的搜寻能力,而且对工程材料提取系统发展起到了参考作用。

Study of the Productive Chain of Stone Facings in Contemporary Buildings in Sao Paulo, Brazil

This article presents, based on field survey and in the consulted literature, the main procedures for fixing of claddings with plates of rocks, adopted in the city of Sao Paulo for buildings and contemporary urban works. There was an increase in the quality of these claddings in the last decades due to several factors, such as the adoption of technological innovations in the extraction process of the rocky material and in the productive chain and, also, the use of most modem procedures for projects in which are incorporated new knowledge for better use of the rocky material and reduction of waste, due to greater demands of the market in the sector of omamental stones.
