Abstract   Spatial  technologies  are  evolving  quickly,  particu larly  with  regard  to  land  related  data.  The  design  of  land  information  system  needs  to  be  efficiently  comprehe nsive  to  take  these  into  account and manage  them  th rough  a Spatial  Data  Infrastructure  (SDI).  The  most  effective  management   with  the  technological  trends  is  likely  to  lie  in spatial  enablement  of  the  various sets of information. SDIs aim to facilitate  and coordinate the sharing of spatial data between  stakeholders, based on a  dynamic  and  multi-hierarchical  concept  that  encompa sses  the  policies,  organizational  remits,  data,  technologies,  standards,  delivery  mechanisms  and  financial  and  human  resourc es  necessary  to  ensure  that  those  working  at  appropriate  (global,  regional,  national,  local)  scale.  Satellite  images  and/or  aerial  photographs,  which  are  one  of  the  ind ispensable  layers  of  spatial  information  systems,  are  quite  important  in   the  context  of  National  Spatial  Data  Infrastructure  (NSDI).  This  study  overviews the Photogrammetry, Orthophoto production  studies and Orthophoto Information System (OIS) in Turkey within the  scope of SDI.
