This  is  a  link  to  a  resource  page  in  Norwegian,  but  gives  access  to  a  lot  of  technical  information  that  also  should  be  informative  to  non-­‐Norwegian  reading  audience.  

The  Norwegian  Mapping  Authority  has  developed  a  default  client  using  this  API,  but  the  API  is  also  exposed  to  third  parties,  and  several  vendors  in  Norway  have  developed  their  own  clients  for  their  customers.  Most  important  here,  are  all  the  municipalities  that  are  responsible  for  maintaining  the  information  in  the  cadastral  system.  

In  the  ESDIN  project,  also  a  WFS  service  compliant  with  INSPIRE  Cadastral  parcels  has  been  developed  (compliant  with  respect  to  data  content,  i.e.  validating  against  the  INSPIRE  GML  schema  for  CP).  The  following  URL  is  an  example  of  a  request  to  this  service  –  unfortunately  this  URL  is  protected  for  the  time  being:

19. Resource  description  The  Norwegian  Cadastral  system  has  a  multipurpose  role  and  is  used  for  a  broad  variety  of  tasks  by  governmental  institutions  /  the  public  sector  and  private  companies.  Today  the  most  important  matters  are  information  for  the  land  market  and  the  planning  activities  and  municipal  services.  

The  Norwegian  Cadastre  is  fully  computerized  as  a  central  database  under  the  control  of  the  Norwegian  Mapping  and  Cadastre  Authority.    

There  are  three  main  units  of  the  Norwegian  cadastral  system:  Information  about  Parcels,  addresses  and  buildings.  The  parcel  unit  comprises  property  number,  area  of  surface,  land  use,  owners  name  /  identification  and  postal  address,  coordinates  for  a  reference  point,  the  cadastral  map  and  cross-­‐reference  to  buildings  and  addresses.  The  address  information  comprises  street  name  and  house  number,  district  codes,  reference  point  and  cross-­‐reference.  The  building  information  comprises  building  identification  number,  type  /  use,  number  of  floors,  numbers  and  data  about  each  flat  (including  identifier),  reference  point  and  cross-­‐reference.

The  cadastral  unit  can  be  mapped  to  the  Inspire  harmonized  model.  

The  lower  boxes,  Building  and  Address,  constitute  separate  important  feature  classes,  and  can  be  mapped  to  the  Inspire  harmonized  models-­‐
