| 摘 要： | 如今主流的地图服务软件中影像图层的发布需要手动指定参数，不利于影像图层自动化发布。本文搭建私有对象存储服务管理遥感数据，利用COG（cloud optimized GeoTIFF）支持局部访问的特性，优化影像瓦片动态创建速度，实现了影像自动发布的瓦片地图服务，改进了瓦片唯一标识码生成算法，提高了瓦片缓存的读写性能。在实例应用中，本文实现的遥感影像地图服务与GeoServer相比，在瓦片动态创建中性能相近，在处理已缓存瓦片时更有优势，具有应用前景。

| Abstract: | The existing image publishing process of a map tile server is complicated because it is not conducive to the construction of an automated process. This paper builds a private object storage service to manage the remote sensing of data. Cloud optimized GeoTIFF (COG) is used to support local access. The dynamic creation speed of image tiles is optimized, and a tile map service that automatically publishes images is realized. In the example application, the remote sensing image map services that are implemented in this paper are similar to those of the GeoServer in the dynamic creation of the COG data tile. |
