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, nearreal-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-tomachine 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
CSISS

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 Hydrometeorological 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
