Coordinates are sets of numbers used to determine the position of a point in a space or on a map.
Coordinates consist of latitude and longitude values
Latitude measures how far north or south a point is from the equator
Longitude measures how far east or west a point is from the Prime Meridian
Coordinates are commonly used in GPS systems to pinpoint locations
A survey begins with planning, site assessment, and gathering necessary equipment and data.
Define the survey objectives and scope, e.g., topographic survey for construction.
Conduct a preliminary site assessment to identify potential challenges.
Gather necessary equipment such as total stations, GPS units, and levels.
Collect background information, including maps and previous survey data.
