Technical Field
The invention relates to the technical field of spatial information service, in particular to a spatial information micro-service packaging and service integration method for a ground information port.
Background
The ground information port relies on a heaven-earth integrated information network, multi-source heterogeneous space-time data are gathered, a distributed cloud public infrastructure environment is built, a unified service open platform is deployed, information fusion of network + remote sensing/geographic information/positioning navigation is realized, industry information application products are distributed, comprehensive service modes such as supermarkets, laboratories and workshops are provided, two-level and three-level market spaces are expanded, and a novel space-time data service hub is created. As a space information distribution center, a ground information port needs to realize real-time access, efficient distribution and data processing on demand of space data, and needs to realize dynamic open integration of multi-source and heterogeneous space applications.
A plurality of space information cloud platforms exist at home and abroad to realize the access, processing and distribution of space data. Such as Google Earth Engine, american eos (Earth observation system), european space agency Earth observation on-demand service grid (G-POD), domestic natural resource satellite image cloud service platform, remote sensing market, etc.
The Google Earth Engine is a cloud platform for online visual computing and analysis processing. The platform has access to data in satellite images and other earth observation data databases and provides sufficient computing power to process such data. Compared with traditional image processing tools such as ENVI (the environmental for visualization images), the Google Earth Engine can process large number of images in batches quickly. Through the Google Earth Engine, Vegetation indexes such as NDVI (normalized Difference Vegetation index) and the like can be rapidly calculated, and crop related yield can be predicted, drought growth change can be monitored, global forest change can be monitored, and the like. The Google Earth Engine provides not only an online JavaScript API, but also an offline Python API. Web services based on Google Earth Engine and Google cloud can be established rapidly through the APIs.
The united states EOS is constantly institutionally integrated with the EOS system, integrating all processing, storage management and distribution services from terrestrial resource satellite (Landsat) data to all subsequent geostationary satellite data into the EOS system. EOS System EOSDIS (earth observation System Data and Information System) is constructed for storing remote sensing Data. The EOSDIS adopts a distributed system architecture, divides remote sensing data into various data centers according to the scientific field for storage, adopts a uniform data storage format (namely an HDF-EOS data format) as a standard format of an EOS data product, and provides a uniform data access interface.
The European Space Research Institute (ESRIN) adds a European data Grid plan, establishes a Grid Processing on Demand (G-POD) Grid for remote sensing data, Processing algorithm and shared distribution of computing resources, reduces the possibility of repeatedly collecting and Processing the remote sensing data and redeveloping the algorithm, and provides a collaborative platform for experts of different disciplines. G-POD guarantees that certain earth observation data processing can be seamlessly embedded into the system, and G-POD provides the flexibility necessary to establish a virtual environment in combination with the high-performance, large-scale computing resources managed by grid technology.
A natural resource satellite image cloud service platform developed by the national native satellite remote sensing application center of the national natural resource department and Beijing national star mapping information technology Limited provides sharing and distribution services of remote sensing image resources of satellites such as a resource No. three (ZY-3), a resource No. one high score (GF-1), a resource No. two high score (GF-2), a resource No. four high score (GF-4) and the like. The platform provides functions of space data query and download, data push, satellite orbit transit prediction, image cloud production and the like.
The Chinese remote sensing and Chinese resource satellite application center develop a remote sensing cloud service platform of the remote sensing market. The cloud service function is provided, and the remote sensing cloud workbench service is provided for data acquisition, processing, storage and online application development. The data acquisition function can download and use remote sensing urban satellite group image data such as GF-1, GF-2, ZY-3, Planet, ZY-02C, MODIS, HJ and the like. The remote sensing market can freely upload software tools and configure a personal cloud workbench on line. Meanwhile, the results can be freely stored and can also be released to remote sensing market trading.
In the spatial information cloud service platform, the Google Earth Engine provides the API for packaging various data processing and displaying functions, and enables users to write applications and process data through online and offline programming methods. G-POD also provides seamless integration capabilities of data processing applications and provides a convenient way for applications to access data, acquire computing resources, and manage computing tasks. However, both Google Earth Engine and G-POD require that applications be written using their specific APIs in their specific cloud environments. Existing applications are transplanted to Google Earth Engine or G-POD with great difficulty and development workload.
The natural resource satellite image cloud service platform and the remote sensing mart also provide open integration capability based on services, for example, the natural resource satellite image cloud service platform can release data algorithms therein, and the remote sensing mart allows uploading of own software tools. However, these two platforms are primarily focused on satellite-specific data access and distribution, and the ability to integrate openly for data analysis and processing functions is relatively inadequate. Spatial information services deployed in the cloud lack the necessary service governance capabilities.
