To ensure accurate meaning, some terms were written following the
criteria below.

- Map → '맵' : 'Map' is rendered as '맵', which is more commonly used than
'지도' in GIS tools.
- Stops → '기준점' : Transliterating the term as '스톱' does not clearly
convey its meaning. Since it represents a reference point used for
interpolation, it is translated as '기준점'.
- Light → '라이트' : Literal translations such as '광원', '빛' or '조명' awkward
in a 3D rendering context, so the term is transliterated.
- Focus → '포커스' : The literal translation '초점' sounds awkward in a UI
context, so it has been transliterated for clarity.
- Terrain → '터레인' : In the context of 3D maps, '터레인' is a more commonly
used term than '지형'.
- Paint → '페인트' : The term is transliterated to preserve its meaning as
defined in the Style Specification.
