Clinometer:Allows you to measure the vertical angle (steepness) of a slope; helpful for assessing avalanche hazards and the heights of objects. Global needle:This feature compensates for magnetic-field variances and allows a compass to work smoothly and accurately worldwide. Otherwise, a compass is...
but I've skipped them in this tutorial since this is more of an introduction to the methods of altitude tracking. For a quick and relatively accurate estimation of altitude, the elevation-angle-only method works well. Other methods, such as the alt-azimuth tracking method, often require multip...
Change azimuth angle measure: (4)Azimuth_math= 360.0 -Azimuth+ 90.0 Note that ifAzimuth_math>= 360.0, the following is true: (5)Azimuth_math=Azimuth_math- 360.0 Convert to radians: (6)Azimuth_rad=Azimuth_math* pi / 180.0 Compute slope and aspect ...
Test the accuracy of the theodolite by using it to measure a known height -- for example, the height of a house. Place the theodolite on a level surface at a measured distance (the baseline) from the house, and adjust the upright post until the apex of the roof is sighted through the...
Use the compass on your phone to determine the Azimuth Angle of the roof face you’d put solar panels on (closest to 180 degrees is best) Based on the map, about half of the US gets less than 4.5 peak sun hours and half gets more, so we’ll use 4.5 peak sun hours as the figure...
side that represents the distance to the unknown object. Historically, people would use sextants to measure distances between any two points on the Earth's surface. When dealing with objects at sea, you can measure the angle of difference between two objects by turning the sextant on its side...
Some astronomers use their telescopes to make scientific measurements with photometers (devices to measure the intensity of light) or spectroscopes (devices to measure the wavelengths and intensities of light from an object). Make Your Own Telescope Many amateurs prefer to make their own telescopes...

(Boundary-Layer Meterol, 145:383-398, 2012) conducted an experiment to evaluate azimuth and angle-of-attack dependent errors of sonic anemometer measurements. Several questions are raised regarding the experimental design and the presented results. The finding that instruments with non-orthogonal sonic...
Repeat this process for the second object you are making a line of sight with. The difference between their azimuths is the horizontal angle. Repeat this step for each horizontal angle you wish to measure. Step 2 Add up the relevant horizontal angles. If you are attempting to record the av...
