Galen Scott from NOAA joined the call to discuss happenings in NOAAs development and release of the new modernized National Spatial Reference System in the US. Javier Jimenez, Even Rouault, and Galen Scott discussed a number of topics:
- Nothing will be published in EPSG until the NSRS is officially released. It is expected that the ratification of the NSRS will happen in FGDC in the first half of 2027.
- PROJ will not have support for the NSRS in released software until its artifacts are registered and published to EPSG and a subsequent PROJ version is released.
- Javier has created an auxiliary database that includes NSRS artifacts and support for testing and evaluation at https://github.com/jjimenezshaw/NSRS-2022-PROJ Users can utilize this resource for testing the NSRS within their own applications.
- PR review activity
gdal raster blend– multiply, screen, overlay, hard, lighten, darken, color burn, and color dodge, with the possibility of easily adding more. See OSGeo/gdal#13688 for details
- PR reviews
- Attempted to get SWIG argument names properly described in Python bindings, but he backed away due to worrying about the number of subsequent test changes its implementation was causing. Such an implementation is likely to cause silent bugs for user-land code :(
- Updated
