[Geotools-devel] [JIRA] (GEOT-5241) support time dimensions with different names across datasets

[Daniele Romagnoli (JIRA)]

Title: Message Title

Daniele Romagnoli created an issue   GeoTools / GEOT-5241 support time dimensions with different names across datasets Issue Type: Improvement Affects Versions: 14.0, 15-beta Assignee: Daniele Romagnoli Components: coverage-multidim Created: 05/Oct/15 5:14 PM Fix Versions: 14.1, 15-beta Priority: Medium Reporter: Daniele Romagnoli When opening different grib files using UCAR NetCDF Java libs you may get the same variable using different time dimensions across different files. As an instance: file1.grib2 dump ============= air_temperature(time1, lon, lat) air_temperature_hourly_maximum(time2, lon, lat) file2.grib2 dump ============= air_temperature(time2, lon, lat) air_temperature_hourly_maximum(time1, lon, lat) (see the swapped time1, time2 dimension names). The name depends on the position of a specific GRIB record within the dataset itself. Since GRIB records are "sparse" records within a binary format the order the parameters are found can't be known in advance, resulting in this "timeX" dimensions "random" naming. This results in issues populating a granules catalog since the dimension<->schema attribute mapping isn't respected anymore. Adding a flag to map all "timeX" dimensions to simply "time" attribute in DB will solve the issue. Add Comment   This message was sent by Atlassian JIRA (v7.0.0-OD-07-011#70107-sha1:db940e9)
