PLANE TABLE SURVEY AND ITS ACCESSORIES In plane table surveying a table top, similar to drawing board fitted on to a tripod is the main instrument. A drawing sheet is fixed on to the table top, the observations are made to the objects, distances are scaled down and the objects are plotted in the field itself. Since […]

LESSON Note on Computation of area and volume The main objective of the surveying is to compute the areas and volumes. Generally, the lands will be of irregular shaped polygons. There are formulae readily available for regular polygons like, triangle, rectangle, square and other polygons. But for determining the areas of irregular polygons, different methods […]

Method to calculate interpolation step value in Excel Summary The following Microsoft Excel formula performs linear interpolation by calculating the interpolation step value =(end-start)/(ROW(end)-ROW(start)) where end is the cell address of the larger number, and start is the cell address of the smaller number. Interpolation is a method used to determine a present or future value factor when the exact […]

Lesson Note On Contours- Map preparation The art of determining relative altitudes of points on the surface of the earth of beneath the surface of earth is called LEVELLING. A contour is defined as an imaginary line of constant elevation on the ground surface. It can also be defined as the line of intersection of […]

CONCRETE MIX DESIGN PROCEDURE & EXAMPLE IS456 Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one […]
