Sedimentary rocks are not harder than igneous rocks. (Eg Lime Stone used for lime mortar). Hard Stones (Eg Granite) are used Floor tilling, wall tilling and specials decorative works uses fine aggregate as building materia

Senior Lecturer  Department of Surveying and Geodesy Faculty of Geomatics Sabaragamuwa University of Sri Lanka. 70140, Belihuloya. Branch of surveying in which both horizontal & vertical distances between stations are determined from instrumental observations (Agor, 1996). Uniqueness! No need of slope corrections, tension, etc... since no chaining involved. Rapid & convenient Good for rugged terrains with deep valleys, mountains, across water bodies... But low accuracy... Purpose; Preparation of contour plans with details. Widely used in preliminary site locating for railways, roads, canals, reservoirs, etc...
