| 摘 要： | 地理国情是国情的重要组成部分，是与地理空间紧密相连的自然环境、自然资源基本情况和特点的总和。影像控制点作为地理国情重要组成之一，其数据生产以及成果质量具有重要意义1]。当前处理影像控制点方式需大量人工操作，过程复杂且效率低下，本文深入分析影像控制点规范，提出基于GDAL的自动提取方案，并开发出影像控制点自动提取软件，可大幅度提高影像控制点生产效率，为地理国情普查提供保障。

| Abstract: | As an import part of National Condition;Geographic condition refers to the sum characteristics of natural environment and resources closely linked to geospatial .Image control point as one of them , its production and quality is very important achievements . Current treatment methods required manual operation , complex and inefficient .After depth analysis of the specification in this paper , an automatic image control point extraction solutions based on GDAL was proposed , and implements software , which could improve production efficiency significantly .Guarantee the successful completion of the National geographic condition survey task . |
