SASM/GNC romanization in the context of "Guma County"

The SASM/GNC/SRC romanization of Standard Tibetan, commonly known as Tibetan pinyin or ZWPY (Chinese: 藏文拼音; pinyin: Zàngwén Pīnyīn), is the official transcription system for the Tibetan language in China. It is based on the pronunciation used by China National Radio's Tibetan Radio, which is based on the Lhasa dialect. It has been used within China and international cartographic products as an alternative to the Wylie transliteration for writing Tibetan in the Latin script since 1982.

Tibetan pinyin is a phonetic transcription, and as such its spelling is tied to actual pronunciation (although tone is not marked). Wylie on the other hand is a transliteration system, where mechanical conversion to and from Tibetan and Latin script is possible. Within academic circles, Wylie transliteration (with a v replacing the apostrophe) is more commonly used.
