The study of Oblique Mercator projection for large scale mapping of the territory of the Republic of M oldova

Sometimes the shape, direction and size of the country territory leads to use a single zone for certain map projection, where the central axe have to coincide with direction of the largest expanse of territory angularly to the axial meridian. Taking in account that the territory of Republic of Moldova is extended from South-East to North-West it was proposed to use as original meridian the central line along the country fitting of the 2,5 degree zone. This paper presents the results of study of Oblique Mercator map projection for large scale mapping of territory of our country in order to reduce deformations on the margin of the zone. Comparative study between TMM (Transverse Mercator for Moldova) map projection, currently used for large scale mapping, and Oblique Mercator map projection sowed the reduction of deformations on the margins of the zone from 16 to 8 cm/km.
