Determination of the angle of convergence
Knowledge of the projections is necessary for the proper determination of the angle of convergence of the meridians (s) for laying the position on the map. In defining s to calculate the great circle travel angles for Conformal Conic projection, the expression
s = (l1 — l2)sin javer,
where: javer - the average width between the intersecting parallels, which are taken as the basis for constructing the maps for a given area;
s = 0,
s = l1 — l2
CHECKLIST
1. Units of measurement scales:
2. length of arc on the equator in the 1 ° = 111,196 km » 111,2 km
1 = 185326m » 1,853 km
1 "= 30.9 m
3. Given track angle (GTA) is the angle made between the northern direction of the meridian taken as the reference point and the line of the given path. It is measured from the prime meridian northerly direction to the direction of the intended track in a clockwise direction from 0 to 360°.
4. Loxodromic Line on the surface of the globe, crossing the meridian at a constant angle.
5. Loxodromic track angle (ZIPU) for each leg is measured directly on the map protractor regarding the central meridian of the site
6. Orthodrome is called the arc of a great circle is the line of intersection of the surface of the sphere (approximating the Earth's surface) plane passing through its center. which is the shortest distance between two points on the surface of the globe. Orthodromy crosses the meridian at different angles.
