Haversine accuracy
WebThe Haversine ('half-versed-sine') formula was published by R.W. Sinnott in 1984, although it has been known for much longer. At that time computational precision was lower than today (15 digits precision). With current precision, the spherical law of cosines formula appears to give equally good results down to very small distances. WebApr 13, 2024 · The Haversine Distance is the primary focus of this paper as it is a more intuitive and comprehensible measure of accuracy. From Table 5 , it can be seen that besides the execution time, WOA-Attention-BILSTM has the lowest metrics, and its average Haversine Distance reaches 0.4042 km.
