Interface for Exposing Earth Science Data Services via ECHO Reverb and Other Clients
Abstract
Due to recent technical advances, many Earth Science data providers now offer their data via easily accessible online archives, providing access to data without the need for a formal order or retrieval from tape. With this increased ease of access, the next logical step is to expose on-demand services to end users to provide further value on this data. With on-demand services, data can be easily accessed in either its native form, or with processing applied, making it easier to integrate with other systems and software packages. Earth Science data clearinghouses provide a unified portal for searching and ordering data managed by various providers. NASA's Earth Observing System ClearingHOuse (ECHO), for instance, provides a user-facing client (Reverb) which allows end users to search for data which can then either be ordered or directly downloaded. In addition, ECHO lets providers define services on their data, allowing end users to request their data either in its native form or with their desired processing applied. The EOSDIS Core System (ECS) Distributed Active Archive Centers (DAACs) now expose such services to ECHO (as well as other clients). The ECS service API, called EOSDIS Service Interface (ESI) supports many common types of processing, such as reprojection, reformatting, spatial/band subsetting, and resampling. These services are now presented to users of Reverb when they add data with the ESI service enabled to their shopping cart. This presentation will provide a brief overview of the ESI API, including: -Services provided by ESI -Current operational usage -Integration of additional provider specified services. In addition, the presentation will draw on the experience of developing and integrating ESI to: -Discuss how the ECHO APIs facilitate integration and exposure of provider specific services. -Discuss the ECHO forms API and how it enables generation of dynamic user interfaces for defining service options.
