Zolemba za kuwerengera kovuta

Zikalata zosinthika Type Movable Type Scripts ndi webusaitiyi yomwe imapereka zida zovuta ku Javascript ndipo zina mwapamwamba kwambiri, zogwiritsa ntchito pa geomatics.

Zina mwa zothandiza kwambiri ndi izi:

Kuwerengera mtunda kuchokera ku makonzedwe awiri (lat / yaitali)

maulendo a haversine Amayesa mtali wafupi kwambiri pogwiritsa ntchito fomu Haversine, zimangofunika makonzedwe azomwe zidachokera komanso komwe akupita kuti alowemo. Sikuti imangopanga zotsatira za kuwerengera koma nambala yake yalembedwa, cholumikizira kuti muwone vekitala mu Google Earth ndi chilinganizo chopambana.

Ili ndilo ndondomeko yeniyeni:

d = acos (popanda (lat₁) popanda (lat₂) + cos (lat₁) .cos (lat₂) .cos (nthawi yaitali₂-kutali₁)) R

Ili ndi JavaScript code:

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

Ili ndilo ndondomeko mu Excel:

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

Kuphatikizanso apo mukhoza kuwona zizindikiro zowerengera monga:

Kuwerengera mwachilungamo
Midpoint
Kupita kumalo kumalumikiza kuchokera ku chiyambi ndi kubala
Chotsatira
Kutembenuka pakati pa madigiri / mphindi / masekondi ndi madigiri a madigiri

Yang'anani, deta imathandiza kwambiri kwa omwe amapanga mapulogalamu, chifukwa amalemba malemba
