Release v4.7.1

2024-09-30

Version description of the v4.7.1 release of SlideRule Earth.

Bathy Version #4.

ATL24 Changes

Fixed default for parameter thresh in C-Shelph.
Fixed calculation of min_surface_photons_per_window and min_bathy_photons_per_window in OpenOceans++
Updated models to latest for QTrees, CoastNet, and Ensemble
Implemented use of geoid_corr_h for all classifiers except for the Ensemble. The Ensemble will be updated once it is retrained on the latest round of test results that incorporate the geoid_corr_h field. Previously, all classifiers were using non-refraction corrected height, but the ensemble was being trained using the refraction corrected height. Also, any post-test-run validation of the results only had the refraction corrected heights in the output. So the geoid_corr_h field was added so that it can clearly represent non-refraction corrected heights, while ortho_h includes the refraction correction (and any future corrections we might add).
QTrees, CoastNet, and OpenOceans++ have been updated with the latest code and are now compiled in as header only libraries.
MedianFilter and C-Shelph are pulled directly from the ut-ATL24-medianfilter and ut-ATL24-C-shelph repositories
Version information is included in for all external classifiers (CoastNet, QTrees, OpenOceans++, MedianFilter, C-Shelph)
Metadata is now provided inside the Parquet and HDF5 files instead of as separate json files.
Uncertainty calculation fixed (migration from python to C and the update to a linear model introduced a few regressions)

Current ensemble model is trained on refraction corrected heights though the inputs are not corrected
Pointnet is identifying very low rates of bathymetry with respect to the other classifiers - we are still working through possible causes

The ATL03 photons are stored in a table in memory and operated on in place instead of streamed
The Python classifiers are all executed from a single Python script that uses multiprocessing instead of having the data transferred to and from disk
