5. SSE SAS project: Snow Cover Maps service/ SSE Workshop ESRIN-Italy / 10 November 2009 INDRA Experience over Snow Cover Maps Snow Cover Map Service Indra Snow Cover Map service 2001-2007  Indra Espacio is working on snow cover monitoring since 2001 (NOAA, MODIS since 2005)  Operational daily service for the Water Basin Authorities of Tajo (2001-2007) and Ebro (2006-2007) Rivers  Water Basin Authorities are public organisations with the mandate to regulate the water flow in the rivers under their responsibility.  They typically run a model capable to make predictions of water flow in the rivers.  One of the key inputs for this model is the estimation of the surface covered by snow. The integration of this information within the model makes feasible a few days forecast of the water flow.

20. SSE SAS project: Snow Cover Maps service/ SSE Workshop ESRIN-Italy / 10 November 2009 20 SERVICE PROBLEMS DURING THE PROJECT Snow Cover Map Service  Development Incompatibility of BPEL tool versions with SSE environment Due to Toolbox 6.0 stability the service or Toolbox were re- installed several times All problems were solved.  Service Snow Cover Maps over the WMV were not supported at Test Portal  migration of the service to operational Portal for testing, according to SSE team. Snow Cover Maps were shown only the first time over the WMV (modifications in WMV by SSE team) Some MODIS datasets covering high latitudes were not managed properly  added restrictions over the AOI selection

Snow Cover Map Service

25. SSE SAS project: Snow Cover Maps service/ SSE Workshop ESRIN-Italy / 10 November 2009 25  Achieved of significant experience in the integration of complex services (subscription and chaining).  Chaining with others companies as MEEO is much easier using SSE.  SSE support (Wiki area) is an useful way of communications.  Web Map Viewer is an useful tool for showing final products. Snow Cover Map Service Learned Lessons

26. SSE SAS project: Snow Cover Maps service/ SSE Workshop ESRIN-Italy / 10 November 2009 26 SUGGESTIONS  More documentation about BPEL is needed. Also tutorials would be appreciated.  BPEL process manager at SSE should be upgraded.  More information about errors detected in the BPEL console and Toolbox should be provided.  Toolbox stability is sometimes limited. (unexpected errors  re-install Toolbox)  Web Map Viewer can not manage large images (4 Mb).  WMV should permit to export final products to.kmz file Snow Cover Map Service
