Mengolo ea lipalo tse rarahaneng

Type Movable Scripts ke websaeteng e fanang ka lintlha tse rarahaneng ho Javascript 'me tse ling li le ntle haholo, bakeng sa lik'homphieutha tsa geomatics.

E 'ngoe ea tse molemo ka ho fetisisa ke:

• Ho khetholla sebaka se lekanang le likhokahano tse peli (lat / nako e telele)

O lekanya sebaka se khutšoanyane ka ho sebelisa foromo Haversine, e hloka feela hore likhokahano tsa semelo le libaka tsa moo li eang li kenngoe teng. Ha e hlahise liphetho tsa lipalo feela, empa khoutu e ngotsoe, sehokelo sa ho bona vector ho Google Earth le foromo e ipabolang.

Ena ke lebese la sebele:

d = acos (ntle le (lat₁) ntle le (lat₂) + cos (lat₁) .cos (lat₂) .cos (e telele₂-e leng₁)) R

Ena ke mokhoa oa JavaScript:

ssp R = 6371; // km SE ssp le d = acos (Math.sin (lat1) * Math.sin (lat2) + Math.cos (lat1) * Math.cos (lat2) * Math.cos (lon2-lon1)) * R;

Ena ke mokhoa oa ho Excel:

=ACOS(SIN(Lat1)*SIN(Lat2) +COS(Lat1)*COS(Lat2) *COS(Lon2-Lon1))*6371

Ho feta moo o ka bona lintlha tsa lipalo tse kang:

• Palo ea lipalo
• Midpoint
• Sebaka se tsamaisana se tsoa ho se seng sa tlhaho le ho jara
• Thuto ea sebapali
• Phetoho pakeng tsa diyure / metsotso / metsotsoana le diperese tsa decimal

Sheba, data e na le thuso haholo ho ba hlahisang lik'homphieutha, hobane e ngotse mekhoa e ngotsoeng
