To convert quadrant bearing to whole circle bearing, add 90 degrees to the quadrant bearing.

• Quadrant bearings range from 0 to 90 degrees.

• Whole circle bearings range from 0 to 360 degrees.

• To convert, add 90 degrees to the quadrant bearing.

• For example, a quadrant bearing of N45°E would become 135°.

To find out the angle and distance of a polygon, you can use trigonometry and surveying techniques.

• Measure the lengths of each side of the polygon using a tape measure or surveying equipment.

• Use a theodolite or total station to measure the angles between each side of the polygon.

• Apply trigonometric formulas to calculate the angles and distances based on the measured values.

• For example, you can use the Law of Cosines to find the angles and the Pythagorean theorem to find the d...read more

The number of satellites a GPS receiver wants depends on its accuracy requirements and the availability of satellite signals.

• The minimum number of satellites required for a GPS receiver to function is 4.

• Most GPS receivers aim to acquire signals from at least 8 to 12 satellites for better accuracy.

• The more satellites a GPS receiver can track, the more accurate its positioning and timing information becomes.

• GPS receivers with Real-Time Kinematic (RTK) capabilities may require s...read more

WGS stands for World Geodetic System, a standard reference system used for mapping and surveying the Earth.

• WGS is a global coordinate system used to accurately represent the Earth's surface.

• It provides a consistent framework for measuring and locating points on the Earth's surface.

• WGS is commonly used in GPS navigation, cartography, and land surveying.

• It uses latitude and longitude coordinates to define positions on the Earth.

• WGS84 is the most commonly used version of the Wor...read more

Contours are lines on a map that connect points of equal elevation, representing the shape and relief of the land.

• Contours are used in land surveying to depict the topography of an area.

• They connect points of equal elevation, allowing surveyors to visualize the shape and relief of the land.

• Contours are typically represented as curved lines on a map, with each line representing a specific elevation.

• The spacing between contour lines indicates the steepness of the terrain - clos...read more

UTM stands for Universal Transverse Mercator. It is a coordinate system used to locate positions on the Earth's surface.

• UTM is a grid-based system that divides the Earth into 60 zones, each 6 degrees of longitude wide.

• It uses a metric coordinate system, with eastings and northings measured in meters.

• UTM coordinates consist of a zone number, hemisphere (N or S), easting, and northing.

• For example, a UTM coordinate might be 32N 500000mE 4500000mN, which represents a location in ...read more
