国产高分辨率遥感影像农村公路核查方法及其应用

传统的农村公路核查需要人工实地抽查或通过GNSS设备进行信息采集验核，存在成本高、效率低等问题。遥感影像具有成像范围广、时效性高、成本低、能客观反映现实情况等优点。相比于传统方法，将遥感影像引入农村公路核查，能客观、准确、高效地对农村公路相关信息进行核查。本文基于国产高分辨率遥感影像，结合农村公路遥感核查业务，采用遥感影像道路提取算法，设计并实现了一种农村公路核查方法。将本方法应用于某中部省份农村公路遥感核查业务，实际应用表明该方法能有效提高现有农村公路遥感核查的工作效率。

Method for rural road verification and its application based on Chinese high resolution remote sensing image

Traditional rural road verification requires manual field spot checks or information collection by GNSS equipment, which has the problems of high cost and low efficiency. Remote sensing images have the advantages of wide imaging range, high timeliness, low cost and can reflect the reality objectively. Compared with traditional methods, introducing remote sensing technology images into rural road verification can complete rural roads verification more objectively, accurately and efficiently. Based on high-resolution remote sensing imagery, combining with rural road remote sensing verification requirements, this paper designs and implements a rural road verification method by using remote sensing image road extraction algorithm. This method has been applied to the rural road verification work based on remote sensing images in some provinces in central China, and the practical application has proved that it can effectively improve the efficiency of remote sensing verification of rural roads.
