Nowadays over 20 institutes companies and offices in Bulgaria develop and apply photogrammetry in various fields of human endeavor. Although the principal photogrammetric activity concerns the making and revision of maps at scales from 1:25 000 up to 1:500, photogrammetry is also applied for various special purposes. In line with the large volume of production,research of a predominantly applied character is carried out. Photogrammetry is taught in 4 technical universities and 6 technical high schools. There are textbooks, instructions, manuals, technologies, etc. while the theoretical and applied publications on photogrammetry in year-books and magazines exceed 1000. The public activity of Bulgarian phogrammetrists is organized by the Photogrammetry and Remote Sensing Section at the Union of Surveyors and Land Managers in Bulgaria, through which they are affiliated to ISPRS. 1. INTRODUCTION Having made its first steps only 30 years following the liberation of the country from Ottoman domination, photogrammetry in Bulgaria has been making steady progress to reach its present state, which corresponds both to the needs of national economy from such an activity and to modern trends of science and technology. 2. HISTORICAL DEVELOPMENT 2.1. Initial Steps (1907-1928) Bulgaria was probably the first country on the Balkan peninsula to begin to apply photogrammetry. The first known photogrammetric surveys in the country were made near city of Sofia in 1907 and 1908. These were plotted in the Vienna Institute of Cartography by Eduard von Orel, using a Stereoauthograph of his own make, Which, as it is known, is the first photogrammetric analog instrument. During the 1912 Balkan War aerial photographs were taken for military reconnaissance, while during World War | (1914-1918) terrestrial photogrammetric pictures were taken of Belasitsa mountain and the Southern front-line for military purposes as well as between the towns of Skopje and Bitola for design of a railway line. Meanwhile an aerial photo was taken of the city of Gabrovo from a Zeppelin in 1917. Later on, in 1920 and 1921 terrestrial photogrammetric pictures were taken around Sofia and of the Rhodope mountain, and in 1926 an aerial photo was taken of Gabrovo from an aircraft. 7 International Archives of Photogrammetry and Remote Sensing. Vol. XXXI, Part B6. Vienna 1996 2.2. Medium-Scale Mapping (1928-1944) A more noteworthy attempt of introducing terrestrial photogrammetry in Bulgaria was made in 1928 when an area of about 2.5 sq. km in the vicinity of Sofia was surveyed by means of the newly-designed Wild Phototheodolite. The area was mapped at the scale of 1:10 000 at the Wild factory, using also the newly- designed A-2 Autograph. Following that successful step preparations got underway for the use of terrestrial photogrammetry in making of a topographic map at 1:25 000 scale. Three Wild phototheodolites and one A-2 Autograph were imported in 1930. At the same time a Wild aerial survey camera and a Hugershoff-Heide rectifier were purchased so that the use of terrestrial photogrammetry for mapping of the mountainous regions of the country began simultaneously with aerial photography of the plain regions. Later on, Zeiss-Jena Multiplex and C-5 Stereoplanigraph and a A-5 Wild Autograph were bought and ever since 1940 aerial photogrammetry has been almost exclusively in use. In 1930 the geodesists V. Peevsky and G. Grozdanov (students of Prof. DoleZal of Vienna) and A. Raikov (a student of Prof. Hugershoff of Dresden) published "A Course in Photogrammetry” which until late 1945 was the standard textbook for all practicing photoprammetrists in the country. 2.3. Large-Scale Mapping (after 1944) Application of photogrammetry for large-scale mapping and for non topographic use made its headway after 1944, aimed at the post-war restoration and intensive development of the country's economy.
