Missing Верныйдан Алматыға дейін: қаланың тарихи трансформацияс
Бұл тарихи карта XIX ғасырдың соңы мен қазіргі кезеңдегі Верный қаласының (қазіргі Алматы) кеңістіктік және урбанистикалық өзгерістерін зерттеуге арналған. Жобаның мақсаты – қаланың тарихи қалыптасу үдерісін, көшелерінің орналасуын, әкімшілік және қоғамдық ғимараттарын салыстыру арқылы оның тарихи-географиялық трансформациясын көрсету. Сонымен қатар, Верный қаласының Ресей империясы кезеңіндегі даму ерекшеліктері мен қазіргі Алматының қала құрылысындағы тарихи сабақтастықты анықтау көзделеді. Compiled by Altynai.
