I'm investigating the most accurate English transliteration of the family name "Каврайский", which is from Владимир Владимирович Кавра́йский, and is used to describe a series of named map projections Проекция Каврайского.
Here are my findings, in order to what I see most common from search engines:
- Kavrayskiy - from Wikipedia's Vladimir V. Kavrayskiy and Kavrayskiy VII projection articles
- Kavraisky - from mapping software PROJ, MATLAB
- Kavraysky - from encyclopedia.com
Which of these is the best? Or are they all valid English transliterations?
