Zvinyorwa zvekuverenga kwakaomarara

Movable Type Scripts iri webhusaiti inopa mazano akaoma muJavascript uye mamwe mune zvakanakisisa, zvekushanda mu geomatics.

Pakati pezvinonyanya kukosha ndeizvi:

• Kuyera kwemafaro kubva kumakwikwi maviri (lat / kure)

Anotora nguva shomanana kushandisa shandura Haversine, zvinongoda kuti marongero eakabva uye nzvimbo dzekuenda kuti apinde. Kwete chete iyo inogadzira mhedzisiro yekuverenga asi iyo kodhi yakanyorwa, hyperlink yekuona vector muGoogle Earth uye fomula iri nani.

Ichi ndicho chirevo chaiyo:

d = acos (pasina (lat₁) pasina (lat₂) + cos (lat₁) .cos (lat₂) .cos (kureba₂-refu₁)) R

Iyi ndiyo code JavaScript:

hadde R = 6371; //? Km hadde D = acos (Math.sin (lat1) * Math.sin (lat2) + Math.cos (lat1) * Math.cos (lat2) * Math.cos (lon2-lon1)) * R;

Uyu ndiwo mazano mu Excel:

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

Uyezve unogona kuona nheyo dzekuverenga zvakadai se:

• Course calculation
• Midpoint
• Enda kune imwe nzvimbo inotarisana kubva kune imwe yekutanga uye kutakura
• Browser course
• Kutendeuka pakati pedhigirii / maminitsi / masekondi uye nedhigirii

Tarisa, iyo data inobatsira kune avo vanovandudza mapurogiramu ewebhu, nokuti yakanyorwa maitiro
