Requirements

• The increasing demands of agriculture drought information– Response: timely?– Resolution: fine?– Accuracy: good?– Coverage: global?– Interoperability: adequate?– Data and services: persistent?– User services: On-demand?– …


problems

Current drought information systems are mostly limited:

• Not compliant with open standards

• Not interoperable with GEOSS

• Coarse spatial and temporal resolution

• Most of them only at regional level

• Limited drought information dissemination

– only map view

– No drought data customization and download

• No or limited service/analysis capabilities

– Separate and incompatible services

– Lack of historical drought data analysis

– Inefficient drought prediction and estimation


Goal and Objectives

• To develop an operational framework and base system for producing and disseminating agricultural drought information from time-series Earth observation data.– To assimilate Earth observations to generate agricultural

drought indicators– To develop an open geospatial Web service system for

global drought monitoring and forecasting– To foster the collaboration among the community to

support the operation of a geospatial Web system for global agricultural drought monitoring


GADMFS

• To address a comprehensive solution to major problems of current agriculture drought information systems by providing global, near-real-time, refined (in terms of spatial and temporal resolutions and accuracy), interoperable, and on-demand agriculture drought condition and information products.


User Services

• Product Discovery, Download, and Machine-to-machine Access– provides interoperable, personalized, on-demand data

access services (IPODAS) to end-users for discovering and downloading the drought related data and information products through its web portal

• Geospatial Processing Services – Process and automate

• Customized Product Generation and Serving – Workflow


Approach

• The approach to develop and deploy a global agriculture drought monitoring scenario: to implement a workflow which include and consume EO data services in WCS, to process agriculture drought estimation in WPS, and to present agriculture drought information in WMS.– Multiple GEOSS contributing components and services

from AIP-5 participants as well as components and services registered in GEOSS CSR will be integrated into the workflow to demonstrate the interoperability and collective capabilities.


Focuses

• SBA focus in AIP-5: – Vegetation Condition Index, – Agriculture Drought– Global Agriculture Drought Monitoring and

Forecasting Portal• Components and services to be registered in GEOSS

Registry• The portal can search and discover the data and

processing services registered in GEOSS CSR, and the discovered data and services will be able to access through the portals to support the SBA applications.


Contributions

• Multiple components and services (interoperable) will contribute to the existing GEOSS AIP architecture use cases– Portal (http, WMS, KML): visualize & access,

maintain and support– Workflow management (BPEL & WPS): process

and automate– Processing servers (WPS):process and automate– Data servers (WMS & WCS): Visualize and access


Relationship

• GADMFS is an application system for Agriculture, Water, and Hazards SBA, developed in compliant with OGC standards and GEOSS architecture.

• GADMFS is relevant to multiple GEO SBA tasks – TASK WA-01: Integrated Water Information (incl.

Floods and Droughts)• Component C2 – Information systems for Hydro-

meteorological Extremes


notes

• For disaster management SBA - on-demand access and processing - Forecasts and events noticing with WNS when agriculture drought occurs- SBA use case scenarios
