LEVELING AND CONTOURING
Leveling is a surveying technique used to determine differences in elevation between points. It involves measuring vertical distances between a fixed benchmark and other points using a leveling instrument, leveling rod, and trigonometric leveling. There are two main methods for leveling - the height of instrument method and rise and fall method. Leveling is used to establish elevations, construct contour maps, and determine cut/fill volumes for engineering projects.
Topography and its representation
This topic includes representation of topography by various non mathematical and mathematical methods.
Pictorial method (Hachure lines, Hill shading)
Mathematical method (Spot heights,Bench marks, Trigonometrical stations, Layer tint or altitude tints, Contour lines )
Combination of different methods
Topographic Maps Notes
This document provides information about topographic maps, including:
1. Topographic maps show elevation, shape of the earth's surface using contour lines connecting points of equal elevation. Features like water, terrain, and human structures are shown through different colors and patterns.
2. Contour lines indicate elevation changes - closely spaced lines show steep slopes, widely spaced show gentle slopes. Contour lines never cross or branch. When crossing streams, they bend upstream. Closed contours indicate hills and depressions.
3. Topographic profiles show elevation changes along a line, often with vertical exaggeration to emphasize details. Gradient is the steepness of a slope. Constructing profiles involves connecting elevation points along a contour line slice
Reading a topographic map
Topographic maps show elevation and surface features of land using contour lines to connect points of equal height. Contour lines never cross and indicate slope - closely spaced lines mean steep slopes while lines far apart indicate flat land.

Distances are calculated using stadia intercept readings and multiplying constants based on the focal length of the instrument's objective lens. Tacheometry offers faster measurement compared to traditional chaining and is useful for surveys in difficult terrain like rivers, valleys, or undulating ground where conventional surveying would be inaccurate or slow.
7 slopes and slope stability
1. Mass wasting refers to the downslope movement of rock and soil due to gravity. It occurs on all slopes and can range from very slow to sudden movements.
2. The stability of a slope depends on a balance between the downward force of gravity and friction/shear strength resisting movement. Steeper slopes and saturated soils or rock are more prone to failures.
3. Common landslide types include rotational slumps and translational slides, which move along concave and planar surfaces, respectively. Earthquakes and rapid addition of water can also trigger landslides.
