摘要:

开放数据立方体系统是新一代开源对地观测数据管理与应用系统,可以解决遥感卫星大数据在管理、服务及应用方面面临的诸多问题,然而,该系统目前仅支持国际主流卫星数据的加载和服务,针对国产数据仍无法使用。以国产卫星数据高分一号WFV数据为例,进行基于开放数据立方体系统的国产卫星数据的加载和服务的设计与实现。首先针对GF-1的数据特点编写产品定义和提取元数据脚本,以建立索引和摄取数据,完成国产卫星数据的加载;然后基于已加载数据,使用Web UI接口开发了GF-1数据的水探测服务。研究结果证明了使用开放数据立方体系统管理国产卫星数据的可行性,并为其他基于该系统的国产卫星数据的加载和服务提供了技术参考。

关键词: GF?1卫星数据数据管理开放数据立方体    
Abstract:

The Open Data Cube system is a new generation of open-source earth observation data management system, which can solve many challenges faced by Chinese satellite big data in the management and application fields. However, the system currently supports only international mainstream satellite data loading and services and is still not available for Chinese satellite data. Taking GF-1 WFV data as an example, we loaded and created a service of Chinese satellite data based on the Open Data Cube system. Firstly, according to the characteristics of GF-1 data, the product definition and metadata extraction script are written to index and ingest data, to complete the loading of Chinese satellite data. Then based on the loaded data, the water detection service of GF-1 satellite data is developed using ODC’s Web UI interface. This research proves the feasibility of using the Open Data Cube system to manage Chinese satellite data and provides technical references for other Chinese satellite data loading and service implementation based on this system.

Key words: GF-1 Satellite Data    Data Management    Open Data Cube
