Flat Earth Dome Model - Walter Blisnis
Here is an interactive Flat Earth Model that can explain Sunrise, Sunset, Moonrise, Moonset, Moon Phases, Moon s apparent rotation, Sun s position on Equinox, Seasons, some aspects of Solar and Lunar Eclipses, Star trails, 24 hours Day Night at the Northpole and Antarctica, Celestial Poles, why people south of the equator can see the same Stars rotate clockwise around a singe celestial pole at the same time at different continents. But many aspects of reality are not solvable by this Model. The flat earth dome model had to be derived entirely from the heliocentric model which results are then simply projected onto the flat earth and the dome. To connect the flat earth projections with the dome projections, light must bend in a physically impossible way.
Rechneronline - Useful Calculators
Calculators, digital tools, for numerous applications, for private, business and school use.

Calculator for the computing of the angular diameter of distant objects.
Earth Curvature Calculator - Omnicalculator
The Earth curvature calculator lets you find the distance from you to the horizon, as well as the height of an object that is partially hidden behind it.
Advanced Earth Curvature Calculator - Walter Blisnis
Use this calculator to calculate and visualize what we can see of a target of a certain size and distance from any observer altitude, taking refraction into account. You can compare the results between flat earth and globe earth. Many more values are calculated and you can customize and store the settings.
