3.6. Land Consolodation Maps For the needs of the land consolidation which began in 1911 but was carried out on a mass footing in Bulgaria during the period 1932-1942, land consolidation maps at scale of 1:2000 are compilated for some lands with total area of about 1.5 thousand sq. km. 4. PHOTOGRAMMETRY 4.1. The Beginning Bulgaria was probably the first country on the Balkan Peninsula to begin to apply photogrammetry. Terrestrial photogrammetric photographs were taken during 1907- 1908 and were plotted in the Vienna Cartographic Institute by Eduard von Orel by means of a Stereoautograph designed by him. During the Balkan War (1912) and the World War | (1914-1918) aerial and terrestrial photographs were taken for military reconnaissance and road construction. More considerable attempt to apply terrestrial photogrammetry for the purpose of compilation a topographic map at scale of 1:25 000 was done in 1928. For the same purpose in 1930 began the implementation of single-image aerial photogrammetry and in 1940 of aerial stereophotogrammetry. For large-scale mapping single-image photogrammetry was applied after the end of World War ll and stereophotogrammetry - since 1954. 4.2. Current Practice The aerial photogrammetry for civil production purposes in Bulgaria is concentrated in the following state enterprises: Geoplanproject Co., Sofia, Geodesia Co., Plovdiv, National Center of Cadastre Ltd., Sofia, Research in Geodesy and Photogrammetry Ltd., Sofia, Patproject Ltd. Sofia, Transproject Ltd. Sofia. Geoplanproject and Geodesia implement analogue stereoplotting of aerophotographs for compilation and revision rural and urban topographic maps at scales of 10 000 up to 1:500. The National Center of Cadastre makes orthophotomaps at scales of 1:10 000 up to 1:2000. Research in Geodesy and Photogrammetry Ltd. accomplishes mainly specific photogrammetric works. Patproject and Transproject make maps at scales of 1:2000, 1:1000 and larger, as well as digital models for the purposes of design and reconstruction of motor-ways for the purposes of design and reconstruction of motor- ways, railways and structures as well as for inventory of the road and railway network. 4.3. The Place of Photogrammetry The place of photogrammetry in the land reform and cadastre in Bulgaria is determined mainly by six of its 82 multiple potentials: (i) Use of retrospective aerial photographs taken over the territory of Bulgaria for compilation of the topographic map at 1:25 000 scale before pooling of private farms into large collective farms. These aerial photographs are taken by normal-angle aerial survey camera (focal length 21 cm, format 18x18 cm) and are at approximate scale of 1:20 000. In the prevailing cases real boundaries of ownership at that time in mountain and hilly regions can be distinguished on them, i.e. where presumably these boundaries have been preserved up to now. (ii) Production of large scale orthophotomaps without contours as basis of the rural cadastre. The orthophotomap is cheaper and is produced considerably faster than the conventional topographic map which make it more up-to-date. The semantic information contained on it is of the same quality and quantity as that on the aerial photographs from which it is made. (il) Production and revision of very large-scale topographic maps in graphical and digital forms as basis of urban cadastre. This is a slower and more expensive process but it is inevitable in view of its high precision necessary for the compilation and updating of the respective graphical and digital maps. (iv) Production of photomosaics and other intermediate photogrammetric products for the purposes of the land reform. The photogrammetry has the advantage that from the instant of taking the aerial photography up to the production of the final product for which it is intended, several intermediate products can be made with different accuracy, serving some intermediate phases of the land reform. (v) Determination of terrain points by aerial triangulation for the needs of land reform and cadastre. Photogrammetry disposes of powerful means for high precision determination of points on the terrain. (vi) Numerical mapping of aerial photographs for compilation of land maps at scale of 1:5000 and larger, necessary for the restitution of ownership of agricultural lands in the existing real boundaries mainly in mountain and hilly regions of the country. Here one should add also the topographic map at scale of 1:5000 which is produced and periodically updated by aerial photogrammetry. 4.4. Basis of Rural Cadastre The orthophotomaps without contours at scales of 1:5000 and 1:10 000 serve as basis for the rural cadastre. For this purpose aerial photographs are taken by a wide-angle aerial camera (focal length 15 cm and format 23x23 cm) from altitude 2.4 or 4.5 km above the terrain where aerial photographs are obtained at approximate scale of 1:16 000 or 1:30 000 respectively. The orthophotoscopy is accomplished by the systems Zeiss Topocart-Orthophot and Topomat.
