Need to fix remaining tests. * Fixed lots of time dtype errors in new NearestNeighbor Interpolator * Missed a transpose in XarrayInterpolator which caused surprising results (but no error) * Added a few more tests for Nearest Neighbor to cover a few tricky cases * Now passing the source bounds through the data source so that bounds can be accurately satisfied on sub-selected data * Now handling -1 indices in NearestNeighbor -- these are set to nans because the do not satisfy the spatial tolerance or are outside the bounds * Fixed an error in interpolation_manager where an exception is raised unfairly. Also added a shortcut to cover a default case (harmless but cuases extra compute) --- podpac/core/coordinates/coordinates.py | 2 +- podpac/core/data/datasource.py | 5 +- podpac/core/data/ogc.py | 2 +- .../interpolation/interpolation_manager.py | 8 +- .../nearest_neighbor_interpolator.py | 143 ++++++++++++------ .../interpolation/test/test_interpolators.py | 37 ++++- .../core/interpolation/xarray_interpolator.py | 2 +- 7 files changed, 141 insertions(+), 58 deletions(-) diff --git a/podpac/core/coordinates/coordinates.py b/podpac/core/coordinates/coordinates.py index e21b47829..bd23d819e 100644 --- a/podpac/core/coordinates/coordinates.py +++ b/podpac/core/coordinates/coordinates.py @@ -76,7 +76,7 @@ class Coordinates(tl.HasTraits): crs = tl.Unicode(read_only=True, allow_none=True) -

Appropriate for grid-to-grid interpolation. +* `ScipyGrid`: An optimized implementation for `grid` sources that uses `scipy`'s `RegularGridInterpolator`, or `RectBivariateSplit` interpolator depending on the method. +* `ScipyPoint`: An implementation based on `scipy.KDtree` capable of `nearest` interpolation for `point` sources +* `NearestPreview`: An approximate nearest-neighbor interpolator useful for rapidly viewing large files + +The default order for these interpolators can be found in `podpac.data.INTERPOLATORS`. + +### NearestNeighbor +Since this is the most general of the interpolators, this section deals with the available parameters and settings for the `NearestNeighbor` interpolator. + +#### Parameters +The following parameters can be set by specifying the interpolation as a dictionary or a list, as described above. + +* `respect_bounds` : `bool` + * Default is `True`. If `True`, any requested dimension OUTSIDE of the bounds will be interpolated as `nan`. + Otherwise, any point outside the bounds will have the value of the nearest neighboring point +* `remove_nan` : `bool` + * Default is `False`.

In that case, if `remove_nan` is `True`, `nan` values will take on the values of neighbors, skewing the statistical result. +* `*_tolerance` : `float`, where `*` in ["spatial", "time", "alt"] + * Default is `inf`. Maximum distance to the nearest coordinate to be interpolated. + Corresponds to the unit of the `*` dimension. +* `*_scale` : `float`, where `*` in ["spatial", "time", "alt"] + * Default is `1`. This only applies when the source has stacked dimensions with different units. The `*_scale` + defines the factor that the coordinates will be scaled by (coordinates are divided by `*_scale`) to output + a valid distance for the combined set of dimensions. + For example, when "lat, lon, and alt" dimensions are stacked, ["lat", "lon"] are in degrees + and "alt" is in feet, the `*_scale` parameters should be set so that + `|| [dlat / spatial_scale, dlon / spatial_scale, dalt / alt_scale] ||` results in a reasonable distance. +* `use_selector` : `bool` + * Default is `True`. If `True`, a subset of the coordinates will be selected BEFORE the data of a dataset is retrieved. This + reduces the number of data retrievals needed for large datasets. In cases where `remove_nan` = `True`, the selector may select + only `nan` points, in which case the interpolation fails to produce non-`nan` data.
