Field Book

In a standard field book all of observations and measurements taken during chain surveying are to be recorded. This is an oblong book of size 200 mm × 120 mm, which may be carried in the pocket.

There are two forms of the book (a) single line and (b) double line. The pages of a single book have a red line along the length of the paper in the middle of the width. It shows the chain line. All chainages are written across it. For sketching the object, the space on either side of the line is used and for noting offset distances. In double line book there are 2 blue lines with a space of 15 to 20 mm is the centre of each book. The space between the 2 lines is used for noting the chainages. Given figure shows typical pages of a field books.
