Background
The Astrogeology Science Center (ASC), under contract with NASA, supports the planetary science community by preparing and hosting planetary datasets. To improve planetary data visualization and analysis capabilities, ASC requires enhancements to the open-source desktop GIS application QGIS, which is heavily used for planetary mapping and mission planning. QGIS supports the OSGeo's GDAL and PROJ libraries, offering strong compatibility with planetary data and projections.

Work Details
The contractor shall deliver code improvements to QGIS that enhance its planetary support, eliminate projection-related bugs, and enable broader usability of planetary map services. Specific tasks include:

1. Eliminate EPSG:4326-related warnings when planetary datasets are loaded into QGIS.
2. Modify QGIS to correctly set base projection based on the first loaded planetary dataset.
3. Resolve geodesic measurement tool bug for planetary radius calculations.
4. Correct scale bar generation to reflect appropriate planetary radius.
5. Enable proper handling of planetary projection codes (+proj=IAU_2015) for WMS/WFS layers.

An optional requirement includes implementing support for geocentric X,Y,Z map projection (+proj=cart) in the 2D QGIS viewer. All deliverables must be committed to the QGIS GitHub repository under accepted contribution standards, compatible with current QGIS builds across supported platforms, developed in C/C++ or Python as required by the QGIS framework, documented, and accompanied by passing unit tests.
