Martin Desruisseaux (JIRA) [jira] [Updated] (SIS-370) Improve CoordinateOperation WKT for axis changes and Molodensky parameters Tue, 30 Apr, 14:11 [sis] branch geoapi-4.0 updated: Refactor WraparoundAdjustment in a way that makes easier to share code between the method working on Envelope and the method working on DirectPosition. Sun, 07 Apr, 19:07 [sis] branch geoapi-4.0 updated: Make GridDerivation.subgrid(…) consistent with GridDerivation.slice(…) regarding IncompleteGridGeometryException being thrown if `areaOfInterest` has a CRS but `GridGeometry` has none. Mon, 08 Apr, 08:12 [sis] branch geoapi-4.0 updated: If correction for ±180° meridian crossing results in a GridGeometry well outside its original longitude range, apply a 360° translation on the whole grid. Mon, 08 Apr, 12:22 [sis] branch geoapi-4.0 updated: Add documentation and checks against integer overflow (ArithmeticException). Make ConvertedGridCoverage package-private and declare ConvertedColorModel as compatible with ConvertedSampleModel only. Avoid the use of MathTransforms.compound(…) since in this particular case an ordinary loop will be more efficient. Mon, 08 Apr, 19:00 [sis] branch geoapi-4.0 updated: Internal class renaming. Tue, 09 Apr, 07:49 [sis] branch geoapi-4.0 updated: Fetching file extension shall work in the case where the given `storage` argument is already an instance of StorageConnector. Tue, 09 Apr, 09:24 [sis] branch geoapi-4.0 updated: Add comment explaining better how the scale factors are computed in `GridDerivation.subgrid(…)`. Tue, 09 Apr, 12:46 [sis] branch geoapi-4.0 updated: Resolve name collision in RasterResource.identifier when two netCDF variables use the same "standard_name" attribute value. Tue, 09 Apr, 14:43 [sis] branch geoapi-4.0 updated: Fix an IllegalArgumentException when creating one-banded image of type DataBuffer.TYPE_INT. Remove ScaledColorSpace from public API (provide a static method instead). Remove ColorModelFactory.getNumBands(ColorModel) method. Wed, 10 Apr, 09:02 [sis] branch geoapi-4.0 updated (3b01827 -> 6092c0a) Fri, 12 Apr, 18:22 [sis] 01/03: Revert commit a685c8a1bf0b412a544713f1ceda9749a995a5d6 (compute linear regression by minimizing errors in grid indices instead than geospatial coordinates). The reason is because the "compute linear regression in reverse way" approach brings more complexity and is not sufficient anyway; we still needs a more sophisticated iterative algorithm in InterpolatedTransform.Inverse. Fri, 12 Apr, 18:22 [sis] 02/03: Add explanation about the "compute linear regression in reverse way" approach that we reverted in previous commit, so if we want to try it again we know which commit to revert. Fri, 12 Apr, 18:22 [sis] 03/03: First draft of an InterpolatedTransform algorithm using derivative (Jacobian matrix) for deciding in which direction to compensate for errors. Not yet enabled. Fri, 12 Apr, 18:22 [sis] branch geoapi-4.0 updated: Refactor the way we use ParameterDescriptorGroup, ParameterValueGroup and "grid to target" transform in GridDatumShift in such a way that we can keep GridDatumShiftFile internal to NADCON and NTv2 transformations. This avoid the confusion declaration of ResidualGrid as a subtype of DatumShiftGridFile. Also moved the DatumShiftGrid.normalizedToGridX/Y methods as package-private methods in DatumShiftTransform; those methods should never have been public, since their relationship with `coordi [...] Sat, 13 Apr, 16:07 [sis] branch geoapi-4.0 updated: Netcdf file opened with the UCAR library should use NetcdfDataset.Enhance.CoordSystems at construction time. Enhancements just before requesting coordinate systems is sometime too late. The symptom we observed was that if metadata were requested before the resources, no grid resources were found because the CS were not found. Invoking NetcdfDataset.enhance(…) at construction time fix that. Sat, 13 Apr, 22:04 [sis] branch geoapi-4.0 updated: Enable InterpolatedTransform.Inverse method based on Jacobian matrix (but still needs more test). Sun, 14 Apr, 17:36 [sis] branch geoapi-4.0 updated: Calculation of derivative outside the grid must be consistent with the way values are extrapolated by `interpolateInCell`. Mon, 15 Apr, 10:55 [sis] branch geoapi-4.0 updated: Add a "Satellite ground track" transform (internal only) for trying to make GCOM data a little bit more linear before to let LocalizationGridBuilder to its job. Mon, 15 Apr, 20:10 [sis] branch geoapi-4.0 updated (6fd90af -> 8b63089) Tue, 16 Apr, 12:51 [sis] 01/03: Tuning of number of itetations and accuracy threshold. Tue, 16 Apr, 12:51 [sis] 02/03: Minor cleanup of debugging code. Tue, 16 Apr, 12:51 [sis] 03/03: Store localization grids using single precision instead of double precision for reducing memory consumption. We presume that single precision is sufficient because the values stored in the `offsets` array are differences, not absolute coordinates. The absolute coordinates will be computed by adding `double` values to those offsets. Tue, 16 Apr, 12:51 [sis] branch geoapi-4.0 updated: Reduce the amount of copy-and-paste in LinearIteratorTest by leveraging the tests provided by DefaultIteratorTest. Tue, 16 Apr, 19:06 [sis] branch geoapi-4.0 updated: Use StrictMath in test classes as a matter of principle. Tue, 16 Apr, 19:06 [sis] branch geoapi-4.0 updated: Do not return NaN for "no convergence" even in the case of extrapolations, because tests have shown that the `grid.isCellInGrid(x, y)` may return `false` (i.e. the point seems to be outside the grid) even when in reality it should have been inside. In other words, we can not be sure that an "extrapolation" is really outside the grid. The algorithm may have fail to converge and think that the point is outside even when the point was deeply inside (not just on the border) if curvatures in loc [...] Wed, 17 Apr, 08:40 [sis] branch geoapi-3.1 updated (d416de4 -> 93dca74) Wed, 17 Apr, 08:49 [sis] 01/01: Merge branch 'geoapi-4.0' into geoapi-3.1. This include mostly netCDF work, with sis-raster improvements in support. Wed, 17 Apr, 08:49 [sis] branch master updated (002121a -> e55b128) Wed, 17 Apr, 09:34 [sis] 01/01: Merge branch 'geoapi-3.1'. The main topic is more development in netCDF reader, together with improvements in other modules in support of netCDF needs. Wed, 17 Apr, 09:34 [sis] branch geoapi-4.0 updated: Edit `GridCoverageResource` contract by allowing `getGridGeometry()` and `getSampleDimensions()` to be slightly different than the corresponding `GridCoverage` properties. Thu, 18 Apr, 09:37 [sis] branch geoapi-4.0 updated: If a netCDF variable contains "flag_names" or "flag_meanings" attribute, create categories for enumeration values instead than for the range of quantitative values. Thu, 18 Apr, 16:59 [sis] branch geoapi-4.0 updated: First draft of "Sinusoidal equal-area" projection, also known as "Sanson-Flamsteed". This commit put only the spherical formulas. Ellipsoidal formulas will come later. Sat, 20 Apr, 21:30 [sis] branch geoapi-4.0 updated (33b6d27 -> 14efbad) Sat, 20 Apr, 21:34 [sis] 01/01: First draft of "Sinusoidal equal-area" projection, also known as "Sanson-Flamsteed". This commit put only the spherical formulas. Ellipsoidal formulas will come later. Sat, 20 Apr, 21:34 [sis] branch geoapi-4.0 updated: Add skeleton base class for meridional distance calculation on ellipsoid. Add formulas to be used as reference in the test class (the formula actually used by implementation may differ). Mon, 22 Apr, 15:59 svn commit: r1858015 - /sis/analysis/ Tue, 23 Apr, 17:33 svn commit: r1858016 - /sis/analysis/Map projection formulas.ods Tue, 23 Apr, 17:41 [sis] branch geoapi-4.0 updated: Implement MeridionalDistance.meridianArc(…). Tue, 23 Apr, 17:45 [sis] branch geoapi-4.0 updated: Adjust the computation of "gridToCRS" in pixel center when derivating from another grid geometry. Wed, 24 Apr, 11:26 svn commit: r1858041 - /sis/analysis/README.html Wed, 24 Apr, 12:31 [sis] branch geoapi-4.0 updated (8158557 -> d2c0625) Wed, 24 Apr, 13:57 [sis] 01/03: Improve comments about the adjustment done for PixelInCell.CELL_CENTER when deriving a GridGeometry from another one. Wed, 24 Apr, 13:57 [sis] 02/03: Rename an "ellipse" boolean parameter as "ellipsoidal". Wed, 24 Apr, 13:57 [sis] 03/03: Fix derivative calculation and add tests. Wed, 24 Apr, 13:57 [sis] branch geoapi-4.0 updated: Implement MeridionalDistance.inverse(double). Wed, 24 Apr, 18:53 svn commit: r1858068 - /sis/analysis/Map projection formulas.ods Wed, 24 Apr, 19:00 [sis] branch geoapi-4.0 updated: Complete the tests for MeridionalDistance inverse method. Thu, 25 Apr, 08:06 [sis] branch geoapi-4.0 updated: Rename "MeridionalDistanceBased" class as "MeridianArcBased" because online dictionaries seem to define "meridional distance" as "the distance or departure from the meridian; the easting or westing", which is not what we mean. EPSG guidance note and Snyder do not use "meridional distance" expression neither for the quantity computed here. Thu, 25 Apr, 09:42 [sis] branch geoapi-4.0 updated: Implement ellipsoidal formulas for the sinusoidale projection. This commit completes Thu, 25 Apr, 13:39 [sis] branch geoapi-4.0 updated: Partial work toward parsing netCDF "grid_mapping" attributes. Thu, 25 Apr, 22:41 [sis] branch geoapi-4.0 updated: Add inference of "grid to CRS" transform from netCDF attributes associated to "grid_mapping" variable. Fri, 26 Apr, 10:36 [sis] branch geoapi-4.0 updated: More complete parsing of "grid_mapping" parameters specified by CF-conventions. Fri, 26 Apr, 16:08 [sis] branch geoapi-4.0 updated (b638306 -> 3dbcae8) Sat, 27 Apr, 16:14 [sis] 01/02: Consolidation of parsing of "grid_mapping" attributes in netCDF file: - Change order of some methods in Convention class for grouping "domain" or "range" aspects together. - Take in account the "latitude_longitude" pseudo-projection special case. - Add a Convention.defaultHorizontalCRS(boolean) method in replacement of CRSBuilder.DEFAULT constant. - Replace some in-line strings for attribute name by constants. Sat, 27 Apr, 16:14 [sis] 02/02: Rename org.apache.sis.metadata.fra module as org.apache.sis.profile.france. The reason is that national profiles may be on other aspects than metadata. Sat, 27 Apr, 16:14 [sis] branch geoapi-4.0 updated: A CSAuthorityFactory containing at least the coordinate system EPSG::4400 should be available even if there is no connection to the EPSG database. This is required for some data stores like netCDF. The CSAuthorityFactory interface is added on EPSGFactoryFallback. Sun, 28 Apr, 15:23 [sis] branch geoapi-4.0 updated: Apply to ConformalProjection the same Snyder 3-35 formulas (trigonometric identities) than we did for MeridianArcBased. Include the coefficients in the serialization, since recomputing values after deserialization may not produce the exact same results than the values computed at construction time. Since we apply a Snyder formula now, those fields shouls be more stable than before. Sun, 28 Apr, 22:22 [sis] branch geoapi-4.0 updated (851bd10 -> 5b271a0) Mon, 29 Apr, 16:34 [sis] 01/03: Cleanup in test and benchmark methods. Mon, 29 Apr, 16:34 [sis] 02/03: Apply to EqualAreaProjection the same Snyder 3-35 formulas (trigonometric identities) than we did for MeridianArcBased. Include coefficients and other fields in serialization for the same reason than ConformalProjection (simplicity, stability). During this work, we identified a bug in the series expansion of φ(β) where the last term was multiplied by e⁸ instead of e⁶. Fixing that bug bring the series expansion to a precision where we no longer need iterations at least with WGS84 ellipsoid. Mon, 29 Apr, 16:34 [sis] 03/03: Include MeridianArcBased fields in serialization for the same simplicity and numerical stability reasons than ConformalProjection and EqualAreaProjection. Inconvenient is that the serialization is more at risk to break if the formulas implemented in those case are improved. However MathTransform serialization should not be used for long-term storage. It is okay for RMI purpose between JVMs running the same version of SIS. Mon, 29 Apr, 16:34 svn commit: r1858383 - /sis/analysis/Map projection formulas.ods Mon, 29 Apr, 16:51 svn commit: r1858419 - /sis/analysis/Map projection formulas.ods Tue, 30 Apr, 10:14 [sis] branch geoapi-4.0 updated: Port the "American Polyconic" projection (EPSG:9818) from Geotk as a side effect of the work on the Sinudoisal projection (those two projections share a common basis coded in MericianArcBased class) and cleanup some tests based on the experience gained by the addition of those two projections. Tue, 30 Apr, 11:20 [sis] branch geoapi-4.0 updated (8ca9f9a -> 9dabf8e) Tue, 30 Apr, 14:11 [sis] 01/02: Remove unnecessary "throws ProjectionException" in Spherical private classes. Tue, 30 Apr, 14:11 [sis] 02/02: Replace "spatio-temporal" by "spatiotemporal" for more uniform spelling. Tue, 30 Apr, 14:11 [sis] branch geoapi-4.0 updated: Remove SimpleIdentifier.toWKT() because not needed anymore, and document why PropertyInformation extends SimpleIdentifier. Tue, 30 Apr, 14:16 [sis] branch geoapi-3.1 updated (93dca74 -> 2751173) Tue, 30 Apr, 14:25 [sis] 01/01: Merge branch 'geoapi-4.0' into geoapi-3.1. Contains work on netCDF and addition of two map projections. Tue, 30 Apr, 14:25 [sis] branch master updated (e55b128 -> 4610eab) Tue, 30 Apr, 14:35 [sis] 01/01: Merge branch 'geoapi-3.1'. Contains work on netCDF reader and addition of two map projections. Tue, 30 Apr, 14:35 [sis] branch geoapi-4.0 updated (b280070 -> 24fcb0f) Tue, 30 Apr, 16:32 [sis] 01/02: Fix a thread-safety hole. Tue, 30 Apr, 16:32 [sis] 02/02: Implements GridEnvelope and GridCoordinates following resolution of Tue, 30 Apr, 16:32 [sis] branch geoapi-4.0 updated: Coverage : add forConvertedValues method Mon, 08 Apr, 09:56
