current project

• check quality of meridian and parallel items

handy concepts

• geographic coordinate system (Q22664)
• spherical angle (Q10396171)
• spherical polygon (Q97367338)

properties each item should have

by item type

• dots a.k.a. geographic position (Q12874993)
  • coordinate location (P625)
• lines (meridian (Q32099), circle of latitude (Q146591))
  • crosses (P177)
• swathes a.k.a. region (Q82794) (integer-degree geographical area (Q139770328))
  • coordinates of northernmost point (P1332)
  • coordinates of westernmost point (P1335)
  • coordinates of geographic center (P5140)
  • coordinates of easternmost point (P1334)
  • coordinates of southernmost point (P1333)

dekagrat table

eight? tables (todo)

if you rotate it 90° counterclockwise, it looks like an Americas-left, north-up world map. ish.
