  2. X Internaional Scientific and Technical ConferenceFrom imagery to map: Digital photogrammetric technologies September 20–23, 2010, Gaeta, Italy INTRODUCTION OVERVIEW THE PROJECT PROCESSING RESULTS AND CONTROL

  3. X Internaional Scientific and Technical ConferenceFrom imagery to map: Digital photogrammetric technologies September 20–23, 2010, Gaeta, Italy • OVERVIEW • From 1 January 2007 Bulgaria become part of European Union • To carry out the obligation like country member ofEU,Bulgaria have to create and update LPIS

  4. X Internaional Scientific and Technical ConferenceFrom imagery to map: Digital photogrammetric technologies September 20–23, 2010, Gaeta, Italy • FUNCTIONS OF LPIS • the unambiguous localisation of all claimed agricultural parcels by farmer and inspectors, • and the quantification of all eligible area for crosschecks during the administrative controls by the paying agency. • LPIS is the single GIS for Integrated Administration and Control System (IACS). • One of the main layer of this GIS is digital orthophotomaps

  5. X Internaional Scientific and Technical ConferenceFrom imagery to map: Digital photogrammetric technologies September 20–23, 2010, Gaeta, Italy Well functioning LPIS will greatly facilitate operations by farmer, inspector and paying agency,resulting in a better overall performance. Obviously, a better LPIS substantially improves IACS effectiveness and management of EU Funds.

  6. X Internaional Scientific and Technical ConferenceFrom imagery to map: Digital photogrammetric technologies September 20–23, 2010, Gaeta, Italy To fulfil the requirements Ministry of Agriculture and Food confide creation of Digital ortophotomaps using satellite imagery for part of Bulgarian territory. The works was implemented by: GIS-Sofia Ltd. Geodetect Ltd. Geokad Ltd.

  7. X Internaional Scientific and Technical ConferenceFrom imagery to map: Digital photogrammetric technologies September 20–23, 2010, Gaeta, Italy • 2. THE PROJECT • Area: • The project is part of territory of Bulgaria • which is around 40.85% of whole area • Purpose of project • Creating digital orthophotomaps using satellite • imagery.
