5. B ROCKMANN C ONSULT GlobCOLOUR DDS Tools GlobCOLOUR CDR, 10-11 Jul 2006 Open Issues 1.Release 1.0 –Which technique to use for resampling of ISIN gridded data onto Plate-Carree? –Flag-coding specification incomplete –No-data value undefined Further planning –Focus on automated analysis of large amounts of data (e.g. time series) instead of visual per-pixel inspection –Identification of use cases concerning match-up and statistical analysis –Review of software requirements in collaboration with the validation team –Consideration of alternative approaches: Is it favourable to implement the match-up processing as a web service?
