| 摘 要： | 地理国情外业调查是地理国情普查工作十分重要的工作内容，是保证地理国情普查数据质量的关键环节。外业调查是对采集的地理国情要素和解译的地表覆盖分类成果以及内业无法定性的类型、边界和属性进行实地调查，同时采集遥感影像样本数据，为最终形成地理国情要素数据、地表覆盖分类数据成果和遥感影像解译样本数据库提供基础。

| Abstract: | Field investigation for general investigation of national geographical conditions is an important part of the general investigation of national geographical conditions , and is the key link to guarantee the data quality of the general investigation of national geo -graphical conditions .Field investigation is the fact -finding process for the collected national geographic condition elements , explained ground mulching classification achievements and the types , borders and properties that cannot be determined within the industry.Meanwhile, field investigation also involves the sample data collection for remote sensing image , which will finally lead to national geographical conditions element data , ground mulching classification data achievements and to lay the foundation for the explained re -mote sensing image sample database . |
