OUTLINEOUTLINE

• Status of CPC GIS conversion

• CPC and NIDIS collaboration on GIS

• GIS and GrADS

MotivationMotivation

• The user communities that are adept at using GIS data would like to include CPC products in their applications.

• Geographic Information System (GIS) format requests are increasing.

• GIS products have interoperability and thus broad applications capabilities

CPC FY08 GIS MilestonesCPC FY08 GIS Milestones

• Convert selected CPC data to GIS format: (Shapefile and GeoTiff)

- Daily Temperature Analyses (United States) - Sea Surface Temperature (Global) - US temperature and precipitation outlooks

• Products will be displayed on the web by end of FY08

ArcGIS ServerArcGIS Server

• The CPC has acquired a copy of the ArcGIS Server Enterprise for Linux

• This software allows processing, extraction and display of GIS geo-referenced datasets including

• Shapefiles • ESRI layers • Raster datasets (geoTIFF) • Other formats using world files

• The server also allows distribution of metadata

NOAA / Web Operation CenterNOAA / Web Operation Center• All NCEP GIS products will be delivered to the public

via the ArcGIS server at the WOC by the end of FY08.

CPC played a key role in the decision to establish the GIS Server on the WOC.

CPC & The National Integrated CPC & The National Integrated Drought Information System (NIDIS)Drought Information System (NIDIS)

• CPC is a member of the NIDIS GIS Team

• CPC GIS DATA conversion in support of Drought Monitoring

• Some of CPC GIS products will be displayed via the NIDIS portal

Facilitating the Transition of Facilitating the Transition of CPC Products to GIS FormatCPC Products to GIS Format

• The Grid Analysis and Display System (GrADS, http://iges.org/grads) is widely used around the world by the climate community including at CPC

• GrADS developed, maintained, and supported by the Center for Ocean-Land-Atmosphere Studies (COLA)

• GrADS is the core software used to generate vast majority of CPC’s web products distributed to the public

Enhancements to GrADSEnhancements to GrADS

• GrADS will be enhanced by adding GIS vector and raster formats as output options

• GrADS scripts used for product generation at CPC will be modified to produce output in GIS format in addition to the native grids and graphical formats already produced
