草原多源遥感数据管理系统设计
Design of Grassland Multi-Source Remote Sensing Data Management System

针对草原多源遥感数据的数据量大、多时相和多数据源等特点，利用强大的ArcGIS Engine二次开发技术，以青海省海晏县为例，设计了一套一体化数据管理系统，从而改进了传统数据管理的不足，实现了对卫星、飞艇、无人机和地面的多源多时相草原遥感数据统一管理、多种数据的相互对比分析。与此同时，系统还实现了对草原遥感数据的查询、分析、制图等基础的方便功能。对于传统栅格影像查询时速度慢、资源消耗大的特点，提出了网格化的解决方案，满足了卫星影像及无人机影像的快速查询的需求，能够对草原多源多时相数据进行更加快速有效的管理和分析，为草原科学放牧以及生态管理提供了决策支持。
Aiming at the characteristics of grassland multi-source remote sensing data, such as large amount of data, multi-temporal and multi-data sources, an integrated data management system is designed by using the powerful secondary development technology of ArcGIS Engine and taking Haiyan County of Qinghai Province as an example, which improves the deficiency of traditional data management and realizes the unified management of multi-source multi-temporal grassland remote sensing data of satellite, airship, unmanned aerial vehicle and ground, and the comparative analysis of various data. At the same time, the system also achieves the basic functions of query, analysis and mapping of grassland remote sensing data. For the characteristics of slow speed and high resource consumption of traditional grid image query, a grid solution is proposed, which solves the need of fast query of satellite image and UAV image, can manage and analyze grassland multi-source and multi-temporal data more quickly and effectively, and provides decision support for grassland scientific grazing and ecological management.
