arc-to-chord correction
Para obtener el acimut cartográfico de la cuerda sobre la proyección habrá que tener presentes dos transformaciones:
convergencia de meridianos.
•Azimut geodésico de la geodésica proyectada
Azimut cartográfico de la cuerda
dTAB y dTBA ángulos de reducción a la cuerda
Para obtener la reducción angular de la cuerda se aplican las siguientes
expresiones:
dTAB=.......... dTBA=.............
Finding values for arc to chord corrections δ1,δ2
Based on formulas (area, avarage radius) we
can obtain the arc-to-chord corrections formula:
δ1= δ2=1/2ε= ρ/2R2 (y1+y2/)/2 (x2-x1)
http://journalofyoungscientist.usamv.ro/pdf/vol_II_2014/art2...
On the basis of the simple relation between spherical excess and arc to chord correction,
formulas to compute the arc to chord correction for different map projections can be derived. If we know the arc to chord correction, however, the spherical/ellipsoidal excess and thus the area of figures on the surface of the sphere or ellipsoid, which are bounded by orthodromes, can be computed simply.
