Tagging guidelines

In general, err on the side of liberality. There is a user button in Georeferencer for "I can't georeference this", so maps that are hard to georeference will be caught at a later stage. But we should still identify them as maps

Not maps, so should not get tagged

Only things which are definitely not maps or plans -- e.g. architectural elevations and details, topographical views, cross-sections, non-geographical diagrams etc. (Some of all of these have been tagged in the past, probably by automated programs).

• 
  Topographical birds-eye drawing of a city
  (But medieval-style maps with drawn houses should be included).
• 
  Stylised birds-eye schematic of an estuary
• 
  Elevation of a building
• 
  Atlas page showing comparative heights of mountains, including two cross sections
• 
  Cross-section through two systems of lakes

Special cases

Please use the additional tags world, conical, and split for the special cases below.

Maps needing rotation should be tagged rotatec (to be turned clockwise), or rotatecc (to be turned counter-clockwise).

1. World maps

Please tag these with the tags world map, or map world

• 
  World map

  Hemisphere map

2. Non-rectangular projections

Please tag these with the tags conical map, or map conical

• 
  Map on a polar projection
• 
  Map on a Cardioid projection, with an not-entirely-sound grasp of geography

3. Images containing multiple maps

Please tag these with the tags split map, or map split

• 
  Sketch of two river systems
•
