Recording of Measurements:
The measurements and other data collected during the process of chain surveying, or for that matter, for any exercise of surveying, it is essential that these are properly and adequately recorded in a systematic way. The records should be easily understood and retrieved by concerned engineers at any time of future reference. There should be provisions to draw explanatory sketches on the record sheets to supplement the information to be given through such data and measurements.
In common, standard field books are used for recording the data and measurements. The field books are made along with good quality plain paper properly and securely bound. It is about 200 mm × 120 mm or 200 mm × 150 mm in size as shown in Figure 16 which also exhibits the sample of records. The chain line is represented through a ruled double line at the middle of each page. Distances along the chain lines are recorded between two lines preferably to scale. There shall be enough space beyond these lines to record offset distances and other distances and also to draw explanatory sketches.
