With the contribution of developing technological and scientific studies, as 3D laser scanning technologies has been providing the opportunity to obtain fast and precise data, they have also become preferable in the documentation of old structures in Turkey. As the historic structures to be protected or the cultural and natural heritage sites included in the architectural discipline vary in terms of size and architectural design, a variety of details with different scales is required for the documentation and survey studies to be conducted. During survey processes, using advanced documentation techniques and technologies facilitates the effective and efficient use of resources. Laser scanning technologies were used during the documentation of Sarn��l� Han, located next to Grand Bazaar�the most valuable spot in Istanbul�and the cistern dating from the Byzantine Period in its yard, after which it was named. In the scope of this paper, the location and the architectural features of Sarn��l� Han and its cistern, the contribution of terrestrial laser scanning technologies to the surveying process, the stages of survey, the problems encountered during documentation, and the process of vectorial drawing realized in a digital environment will be discussed.

Keywords: Advanced surveying techniques, point cloud data, digital surveying, terrestrial laser scanning technology.

Geli�en teknolojik ve bilimsel �al��malar�n katk�s�yla eski eser yap�lar� belgeleme s�recinde, 3 boyutlu lazer tarama teknolojileri h�zl� ve do�ru veri alma olana�� sa�lad��ndan, son y�llarda T�rkiye�de de tercih edilir duruma gelmi�tir. Mimarl�k disiplinine dahil olan korunmas� gerekli tarihi yap� ya da k�lt�rel ve do�al miras b�lgelerinin �e�itli boyut ve farkl� mimari �zellikler g�stermesi nedeniyle, �zerinde yap�lacak belgeleme ve r�l�ve �al��malar�nda, farkl� �l�eklerde �e�itli detaylara ihtiya� duyulmaktad�r. R�l�ve elde edilme s�re�lerinde, ileri belgeleme teknik ve teknolojilerinin kullan�m�, kaynaklar�n etkin ve verimli kullan�lmas�na imkan tan�r. �stanbul�un g�zbebe�i olan Kapal��ar��n�n biti�i�indeki Sarn��l� Han ve hana ismini veren, avlunun alt�nda yer alan Bizans d�nemine ait sarn�c�n belgelenmesinde, lazer tarama teknolojisinden yararlan�lm��t�r. Bu yaz� kapsam�nda Sarn��l� Han ile avlunun alt�nda yer alan sarn�c�n, konumu ve mimari �zellikleri, yersel lazer tarama teknolojisinin r�l�ve s�recine olan katk�s�, r�l�ve a�amalar�, belgeleme esnas�nda kar��la��lan sorunlar ve say�sal ortamda ger�ekle�tirilen vekt�rel �izim s�reci aktar�lacakt�r.

Anahtar Kelimeler: �leri belgeleme teknikleri, nokta bulutu verisi, say�sal r�l�ve, yersel lazer tarama teknolojisi.
