Study Notes

The module is about forest surveying and has three lectures
Surveying is the act of measuring the relative position of natural and manmade features on earth's surface
The information is presented either graphically or numerically
Surveying involves measuring the exact locations of various features like houses, fields, trees, rivers, and hills
The relative position of each feature is measured with respect to a chosen reference point
The location of each feature is measured in terms of distance and angle from the reference point
The measured information is represented on a sheet of paper with a scale
The earth's movement is considered while measuring relative positions
The first lecture is about classical tools while the second and third are about modern tools of Photogrammetry and LiDAR
The purpose of surveying is to gather information about the location of different features on the planet earth.
