# Release v4.8.0
2024-10-15
Version description of the v4.8.0 release of SlideRule Earth.
Bathy Version #5.
## ATL24 Changes
* Fixed issue with ortho_h where it was being set to zero when the surface_h was less than or equal to zero.
* When Kd is invalid (i.e. No Data from the VIIRS raster), the previous Kd is used and an INVALID_KD flag is set
* Fixed issue where the absolute value of the pointing angle is now being used to calculate the pointing angle index
* Fixed issue with the uncertainty calculation where the uncertainties are now the RSS of all the contributing factors
* Fixed issue with the use of the wind speed in the uncertainty calculation where wind speeds are now averaged between five different levels
* Coastnet is used to set the surface_h
* Minimum subaqueous vertical uncertainty set to 10cm
* Refraction correction and uncertainty applied to photons below surface_h AND are not labeled as sea surface
* Classifiers updated: coastnet, qtrees, openoceanspp, ensemble
* Statistics on Subaqueous photons no longer include photons labeled as sea surface
## Known Issues and Remaining Tasks
* CMR queries of ATL09 stopped working - CMR updated their API and removed support for page numbers when scrolling
## General Changes
* GEDI parameters updated to be more accurate an intuitive (the old parameter names are still functional but have been DEPRECATED, please switch to using the new ones in your code).
- `degrade_flag` changed to `degrade_filter` and instead of having to know what the flag values were; the user now just needs to set to True to filter out all degraded footprints.
- `l2_quality_flag` changed to `l2_quality_filter` and instead of having to know what the flag values were; the user now just needs to set to True to filter out anything that does not meet the L2 quality criteria.
- `l4_quality_flag` changed to `l4_quality_filter` and instead of having to know what the flag values were; the user now just needs to set to True to filter out anything that does not meet the L4 quality criteria.
- `surface_flag` changed to `surface_filter` and instead of having to know what the flag values were; the user now just needs to set to True to filter out anything that isn't a surface footprint.
- `beam` changed to `beams` to reflect that it is primarily a list of beams to process and not just a single beam (even though if the user only provides a single beam, the server side code will automatically promote it to a list of beams with only one element).
* Subsetting requests that use a rasterized geojson to perform the subsetting have been changed so that the geojson string is passed via a parameter named `region_mask` instead of `raster`. The original name was confusing with our increasing support for raster sampling. The new name makes it clearer that the parameter is used as a mask for the region of interest.
