Arrange the following steps in ascending order of radiation method of plane table surveying
a- Select a point "O" so that all points to be located are visible from it.
b- Join the points a, b, c and d on the paper.
c- Mark the direction of the magnetic meridian.
d- Centering the alidade on "O" BISECT the objects of traverse A, B, C and D.
e- Set up the table at "O", level it, select a point "O" on the sheet so that it is exactly over station "O" on the ground.
f- Measure the distances OA, OB, OC and OD and plotted to convenient scale to locate a, b, c and d respectively.
