Explanation

 The diagonal scale enhances measurement accuracy and ease

when dealing with various dimensions on maps and technical drawings.

Explanation

 The field record of a chain survey is entered at the field book or survey notebook.

This documentation includes measurements, sketches, and notes taken during the survey process.

Explanation

 The north line of a map is typically marked on the compass rose or north arrow.

This symbol indicates the direction of north and helps readers orient themselves in relation to the map's features.

Explanation

 Calculating the area of an irregular shape might involve several methods of approximation or computational geometry. 

The best approach will depend on the tools available and the level of precision required for the task.

Explanation

 1 link in a 30-m chain = 20 cm

Used in metric land surveys for precise measurements.

Explanation

 A longer chain leads to underestimation of the actual distance.

Explanation

 Standard Length: 33 feet  ,Number of Links: 16

Length of Each Link: 2.0625 feet (2 feet and 0.75 inches)

Purpose:

Used in the Revenue Department for measuring agricultural and land records.

Explanation

Explanation

 In chain surveying, the area is divided into a network of triangles, as triangles provide the simplest and most stable geometric figures for accurate measurements

Explanation

   Surveys that show the natural features of a country are known as topographic surveys
