Open-source resource map

Use these as the upgrade path from teaching schematics into data-driven sky geometry: IAU constellation regions and boundaries, open-source planetarium projects such as Stellarium and KStars, and open star catalogs / sky-culture line datasets where license terms fit the site.

• IAU constellation framework: modern astronomy recognizes eighty-eight IAU constellations, with boundaries adopted in the early twentieth century.
• Stellarium: open-source planetarium software useful as a reference for constellation display patterns and sky visualization.
• KStars: free and open-source planetarium software that includes constellation support and multiple sky objects.
