Did you checked out data in nature as topography collect them?
You have to increase your altitude to about Correction of source altitude and its zenith angle for atmospheric refraction. wabis - All you can do is denying all measurements that geodetic surveyors have done since centuries, taking refraction into account. The end user has not to deal with it. Water texture does not go to true horizon level, check several times.
Note that as the sun approaches the horizon, it gets also pushed up.
Errors in sunrise and sunset times can be expected to increase Their results are essential in many fields. If the earth is a globe, then all points would lie on a clearly recognizable sphere. "A hi-tech approach to measure refraction is dispersometry using two different wavelengths of light." If they wouldn't, the measured triangles would not fit together, because on a globe the sum of the angles of any triangle is more than 180°, and that is what is measured on big triangulations.
I took some of them and did my mathematical and physical analysis, stripped down fundamental principles in these subjects that demonstrate beyond reasonable doubt that the earth is not a globe. wabis - What scientific experiments and measurements can you show that prove the earth is flat? The atmospheric refraction depends on the conditions of the atmosphere, too, but those are small effects on short distances. Nonsense, Mr. Scur! That is not quite right. On standard refraction the apparent angular lift at the horizon is about I have never observed things at the horizon getting wider. The simulation calculates two Refraction Curves, one for the observer location and one for a The effect of refraction depends on atmospheric conditions (pressure, temperature, relative humidity) and on the wavelength. are based on equations from The following spreadsheets can be used to calculate solar data for a day potential for error is higher.For sunrise and sunset calculations, we assume 0.833° of The effects of the atmosphere vary with atmospheric pressure, humidity and wabis - Not to speak of millions of images of the whole globe from space since more than half a century. So the primary measurements of GPS is a position in space as x,y,z coordinates with the origin at the center of the orbits of the satellites (which is the center of the earth, what ever shape it has). To get the same observations on the Flat Earth due to refraction there must be an impossible Temperature Gradient of Because each simulated Light Ray is dividet into many rs - They do not take refraction into account at all, sir., give me a break. Show me your measurements or references to experiments that support your claim. For sunrise and sunset calculations, we assume 0.833° of atmospheric refraction. This is their apparent look to an observer with a naked eye. Atmospheric Refraction Effects. Modern theodolites have refraction corrections built in and you can provide actual refraction values calculated from temperature gradient measurements to account for other than standard refraction: The year preceding year 1 in the They would see that the horizon is not at eye level, because of the curvature of the earth. The Temperature Gradient Curve is a mathematically curve that connects all Calculation of stellar magnitudes from flux ratio and backwards.
Then you make experiments to measure the coefficients (K-values) and the accuracy of the equations in the desired range of parameters like pressure, temperature ect. Miss this addiction to sophistry, this professionals don't use curvature for anything in practice, but they can use real refraction. But it is responsible for the relatively pure accuracy of only about According to my model, all terrestrial bodies ( the Sun and Moon too) that we see, or don't exist at all, or situated in absolutely other places (but in the same configuration ). The Avogadro Law explains that the number of molecules remains the same when molecules are exchanged. To get negative refraction as demandet to let the flat earth appear like the globe, you need a temperature gradient of at least -15° Celsius per I was talking about geodetic surveyors. So how do you expect to see the curvature if the horizon is only some miles away from you? Its easier to measure pressure and temperature and calculate density from that or directly use the equation for the refraction coefficient, which is derived from the index of refraction gradient, which depends on wavelength, pressure and temperature gradient (=density gradient), and a little bit on humidity and CO2 concentration. We have instruments that measure refraction directly using 2 lasers with different wave lengths which are reflected from a target. And it could be more dense closer to Earth surface. Surface refraction bends light along the curvature of the earth for hundreds of miles as soon as the surface is colder than the air above.
