Creation of the Orthophotomap on the Base of Satellite Images for Part of the Territory of Bulgaria

Participants: ASDE, ReSAC, MAF, EUSI, EURIMAGE, SPOTIMAGE, Dian Zlatev-98

The Project's general aim was the creation of Digital Orthophoto map for part of the territory of Bulgaria on the base of VHR satellite images (QuickBird and IKONOS). The financing came by the Ministry of Agriculture and Forestry. After an open international tender the project was awarded to the consortium leading by the Agency for Sustainable Development and Eurointegration – ECOREGION and its specialized center Remote Sensing Application Center - ReSAC. Partners in the consortium are the major European representatives of the companies which deliver satellite images - EUSI, EURIMAGE и SPOTIMAGE. Dian Zlatev-98 took also part in the project as a company responsible for the on-ground survey reference point measurements.

The Project is of extreme importance for the membership of Bulgaria in the EU regarding the Common Agricultural Policy - CAP (LPIS/IACS) and was fulfilled respecting all specifications and recommendations of the DG JRC.

The Satellite Digital Orthophoto Map with very-high resolution (0.7 – 1 m) was created for an extent of 33.364 for Southern Bulgaria. The satellite images are archive data for the period 2003-2005. The digital elevation model used for the orthorectification is product of SPOTIMAGE called Reference3D, which during this project was used for the first time as high-quality DEM at a country scale for the LPIS purposes.

The Project, containing mainly the processes of orthorectification of satellite images, is unique with the short terms for its fulfillment – 3.5 months, and with the introduction of a new methodology, specifically developed for this tasks. The first raw imageries were delivered on 10th of April 2006 and the final orthorectified products were finished on 25th of July 2006.
