摘　　要：为了促使地理国情信息提取技术更趋向智能化,本文以某实验区地理国情信息提取为依托,采用eCognition方法对实验区中的水系和道路信息进行提取,并对道路和水系信息提取的精度进行了评定。试验结果表明,基于eCognition的地理国情信息提取结果达到了地理国情普查的技术要求,可为后续的地理国情普查中可以得到较好的推广应用,并对类似案例提供参考和借鉴。In order to make the technology of geographic national condition information extraction more intelligent,this paper uses eCognition method to extract the water system and road information in the experimental area based on the geographic national condition information extraction in an experimental area,and evaluates the accuracy of the road and water system information extraction.The test results show that the extraction results of geographical national conditions information based on eCognition meet the technical requirements of the geographical national conditions census,can be better popularized and applied in the subsequent geographical national conditions census,and provide reference for similar cases.
