[Geotools-devel] [jira] (GEOT-4677) NullPointerException when reading netcdf file with invalid units in time dimension

[Jeroen Dries (JIRA)]

Jeroen Dries created GEOT-4677 NullPointerException when reading netcdf file with invalid units in time dimension Issue Type: Bug Affects Versions: 11-beta Assignee: Simone Giannecchini Components: coverage, unsupported Created: 24/Jan/14 4:09 AM Description: I have a TAMSAT netcdf file with an invalid units string in the time dimension: 'days since 2007-00-01 0:0:0' This results in an ugly NPE when initializing the UnidataImageReader (stack trace below). I propose to add some logging which clarifies the root of this issue. I would also like to add a workaround in the specific case of a 'time' axis: the unidata-netcdf library refuses to set the axistype if it can not parse the units, which is rather unfortunate for the geotools implementation which heavily depends on this axistype. I would think that a workaround specifically for a given axis type is relevant because the time dimension is very common. A pull request follows. Caused by: java.lang.NullPointerException at org.geotools.imageio.unidata.UnidataImageReader.initMapping(UnidataImageReader.java:381) ~[gt-unidata-11-SNAPSHOT.jar:?] at org.geotools.imageio.unidata.UnidataImageReader.extractCoordinatesVariable(UnidataImageReader.java:416) ~[gt-unidata-11-SNAPSHOT.jar:?] at org.geotools.imageio.unidata.UnidataImageReader.init(UnidataImageReader.java:461) ~[gt-unidata-11-SNAPSHOT.jar:?] at org.geotools.imageio.unidata.UnidataImageReader.setInput(UnidataImageReader.java:253) ~[gt-unidata-11-SNAPSHOT.jar:?] at javax.imageio.ImageReader.setInput(ImageReader.java:380) ~[?:1.7.0_45] at org.geotools.coverage.io.netcdf.NetCDFAccess.<init>(NetCDFAccess.java:116) ~[gt-netcdf-11-SNAPSHOT.jar:?] at org.geotools.coverage.io.netcdf.NetCDFDriver.connect(NetCDFDriver.java:87) ~[gt-netcdf-11-SNAPSHOT.jar:?] at org.geotools.coverage.io.impl.DefaultFileDriver.process(DefaultFileDriver.java:216) ~[gt-coverage-api-11-SNAPSHOT.jar:?] at org.geotools.coverage.io.netcdf.NetCDFReader.<init>(NetCDFReader.java:155) ~[gt-netcdf-11-SNAPSHOT.jar:?] Project: GeoTools Priority: Major Reporter: Jeroen Dries
