摘　　要：针对目前道路面积提取的步骤复杂、成本过高等问题,基于Google Earth与计算机绘图软件的联用,提出2种道路面积提取方法-"Photoshop+ArcGIS"联用技术和"Map Info+ArcGIS"联用技术,并以石家庄市3条代表性路段(建设大街、青园街和范西路)为例进行道路面积提取。研究结果表明,与单一信息提取技术相比,所提出的"Photoshop+ArcGIS"和"Map Info+ArcGIS"联用技术均具有简单、便捷、成本低和精确度高的特点,其中前者的精确度较后者更高。Aiming at the problems of the road area extraction methods,such as complex steps and high cost,based on the combination of Google Earth with the computer drawing softwares,we propose two road area extraction methods,one is the combination of Photoshop with ArcGIS（＂Photoshop ＋ ArcGIS＂）,the other is the combination of Map Info with ArcGIS（＂Map Info ＋ ArcGIS＂）,and as the samples,the road area of the three representative roads of Shijiazhuang city（Jianshe street,Qingyuan street,Fanxi road） are extracted.The results show that,compared with the single information extraction technology,the two coupling methods of ＂Photoshop ＋ ArcGIS＂and ＂Map Info ＋ ArcGIS＂have the advantages,such as simple,convenient,low cost and high precision,and the ＂Photoshop ＋ ArcGIS＂has a higher accuracy than the ＂Map Info ＋ ArcGIS＂.
