基于GIS的海量DOM影像数据重采样系统的设计与实现

Design and Implementation of Massive DOM Image Data Re-sampling System Based on GIS

针对天地图·云南平台数据更新的需求,提出了基于地理信息系统(GIS)的海量DOM影像数据重采样系统的设计方案,论述了系统的结构以及实现方法。重点对系统的整体框架、功能设计和系统实现进行了详细介绍。有效解决了将1:2000DOM影像批量化重采样为1:5000DOM影像的问题,完成了天地图·云南平台数据更新工作。

Aiming at the demand of Map World·Yunnan platform data update, a design scheme of massive DOM image data re-sampling system based on geographic information system(GIS) is proposed, and the structure and implementation method of the system are discussed. The focus is on the overall framework, functional design and implementation of the system. It effectively solves the problem of re-sampling 1:2000 DOM image into 1:5000 DOM image, and completes the data update work of Map World·Yunnan platform.
