CEOS WGISS & Subgroup Meeting, Beijing, September, 2004
Introduction
As part of its overall International Co-operation Programme in EO, BNSC is supporting a number of small study/technology demonstrators relating to OGC (and GRID):
ICEDS: Integrated CEOS European Data Server (contribution to CLASP)
EMIR: Environment for Metadata and Image Retrieval
Support for the OGC EO SIG Study on the relevance of OGC/GRID for GMES Study on Harmonisation of Met. and EO Data Formats
These are mostly due to finish soon. Should be able to make results available at next WGISS meeting
Also have nrt-modis activity (part funded by ESA)
CEOS WGISS & Subgroup Meeting, Beijing, September, 2004
EMIREnvironment for Metadata and Image Retrieval Provide OGC interfaces into legacy catalogue and data archives
Continuation of GAZE (presented at last meeting)– GML Access from Z39.50 Environments
Access to Z39.50 catalogue systems – (e.g. FGDC Clearing House, UK GI Gateway and UK NERC Data centres).
Requested data is hosted, on the fly– on OGC WMS for browse (Minnesota)– on WCS for data
Using DeeGree WCS

Data retrieved from WCS

Use of Deegree WCS
Currently, limited output formats (will include geoTIFF)
Some lack of maturity, i.e. some bugs
DeeGree development team responsive to queries and bug fixing
Blurring distinction between WMS & WCS

NRT-MODIS System
Uses Minnesota WMS for Browse
Uses George Mason University WCS (contact Liping Di)
AVHRR and MODIS 1km browse data available over Internet within ~2hrs of data take.
Ordering system for Level 1b data via WCS
Need additional data viewer for WCS output!

Use of GMU WCS
Good for MODIS hdf data
Handles other formats too
Client providing access to WMS, WFS and WCS available
