ITN-­‐DCH Case  study  III   Castle  of  Donaustauf  

HISTORY The  township  of  Donaustauf  is  situated  10  km  in   the  East  of  Regensburg  (southern  Germany).   The  small  city  is  dominated  by  the  ruins  of  the   castle  Donaustauf.  The  castle  sits  on  a  hilltop,   approximately  100m  above  the  Danube.  It  is  the   oldest  castle  menLoned  in  documents  within   the  area  of  Regensburg.  Between  914  and  930,   several  records  can  be  found  that  menLon  a   castle  which  is  called  Stauff  (castellum  quod   dicitur  Stuffo).  It  is  assumed  that  the  castle  was   erected  by  Bishop  Tuto  of  Regensburg  (893– 930),  as  a  defence  against  the  Hungarian   invasion.  However,  archaeological  excavaLons   revealed  that  at  least  the  North-­‐Eastern  part  of   the  hilltop  was  forLfied  about  500  B.C.  already.     Donaustauf castle (credit Andreas Boos).

STRUCTURE Over  the  centuries,  sector  forLficaLons  have  been  built  to  protect  the  castle.   In  other  words,  the  hill  on  which  the  castle  stands  was  forLfied  from  top   to  boWom  and  this  forLficaLon  was  adapted  to  the  different  needs  of  the   Lme.  The  oldest  part  dates  back  to  the  11th  century,  the  last   strengthening  was  carried  out  in  1620.       To  protect  the  central  part  of  the  castle,  six  gates  were  built  (A-­‐F).  Only  four   of  them  are  visible  today.  The  most  impressive  gate  is  the  most  inner  gate   to  the  bailey  castle  (gate  F).  The  entrance  is  covered  by  two  groin  vaults   that  are  separated  by  a  wide  arch.  In  the  first  floor  of  the  building  even   today  the  castle  chapel  is  sLll  visible.    

DATA AVAILABLE   There  is  already  a  set  of  data  available  which  was  recorded  by  ArcTron3D   (ITN-­‐DCH  partner).  This  dataset  can  be  used  within  this  project  as  a  state   of  the  art  dataset  and  compare  it  to  the  newly  gathered  data.  This  set   contains  aerial  pictures  taken  with  an  ultra  light  paraglide  trike  and  survey   data  of  the  walls  in  the  castle  area.  The  wall  dataset  was  gathered  using  a   laser-­‐scanner  and  SfM-­‐Data.   Gate F

The airborne   technology   will   be   used   to   create   a   model   of   the   hilltop   and   the   landscape.   The   landscape   model   will   include   the   hilltop   of   the   castle,   the   Danube,   the   town   and   part   of   the   backcountry.   The   data-­‐acquisiLon   will   be   done   using   the   ultra   light   paraglide   trike   and   a   Nikon   D800E   camera.   For   smaller   areas   of   importance   or   to   fill   possible   holes   in   the   ground   mesh,   a   UAV   can  be  used.     A  ground  plan  using  GPS  sensors  and/or  laser  scanners  and  the  total  staLons  could  also  be  useful  to   verify  and  update  exisLng  plans  as  well  as  to  georeference  the  object  for  further  detailed  studies  of   the  chapel  and  the  gate.     Made   of   Romanesque   fabric,   Gate   F   is   one   of   the   most   interesLng   parts   of   the   castle.   Therefore,   a   detailed   and   precise   documentaLon   of   it   should   be   done.   Different   methods   of   terrestrial   laser   scanning,  terrestrial  photogrammetry  and  even  airborne  photogrammetry,  using  the  UAV,  can  be   applied.     On  the  preserved  walls  of  the  chapel  there  are  traces  of  painLng,  daLng  back  to  the  12th  It  might   be   interesLng   to   try   to   figure   out   the   whole   story   of   the   painLng   and   the   story   that   is   depicted.   Linking   the   painLngs   of   the   chapel   wall   with   other   content   or   even   bringing   the   figures   back   to   life   will  be  a  challenge  for  the  task  that  concern  the  intangible  CH  part  of  the  project.   The  chapel  itself  is  of  great  historical  value,  being  one  of  the  few  Romanesque  chapels  within  the   region  since  it  sLll  has  some  of  the  original  plaster  such  as  capitals,  columns,  arches,  etc.  Structured   light   scanning   (SLS)   methods   in   comparison   to   photogrammetry   and   infrared/hyperspectral   imaging  can  be  applied  to  document  this  part.     4D   models   of   the   gate   would   also   be   a   possible   task   for   the   project   fellows   using   exisLng   e.g.   informaLon  taken  by  some  rough  sketches  by  the  American  painter  Joseph  Mallord  William  Turner   and  other  arLsts  integrated  with  2D  and  3D  Content.    

ACQUISITION PLAN   Techniques  available     •  Structured  light  scanner   •  Laser  scanner     •  Photogrammetry  (aerial  and  terrestrial)   •  Surveying  techniques    

OBJECTIVE The  main  goal  of  this  case  study  is  to  integrate  all  the  techniques  and   informaLon  available  in  a  disseminaLon  plagorm.  Geometric  data,  as  well   as  historical  an  intangible  informaLon  should  be  included.
