Ederede maka mgbagwoju anya mgbawa

Ụdị Akwụkwọ edemede bụ weebụ nke na-enye koodu mgbagwoju anya na Javascript na ụfọdụ na excel, maka ngwa na geomatics.

Otu n'ime ndị kasị baa uru bụ:

• Nchịkọta nke dị anya site na nhazi abụọ (lat / ogologo)

Na-eme ka ụzọ dị mkpirikpi na-eji usoro Haversine, ọ chọrọ naanị nhazi nke isi mmalite na ebe aga-abanye. Ọ bụghị naanị na ọ na - ewepụta nsonaazụ nke ngụkọta oge, mana edere koodu ahụ, hyperlink iji hụ vector na Google Earth na usoro na Excel.

Nke a bụ usoro nkịtị:

d = acos (na-enweghị (lat₁) na-enweghị (lat)₂) + cos (lat₁) .cos (lat₂) .cos (ogologo₂-Ama₁)) R

Nke a bụ koodu Javascript:

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

Nke a bụ usoro Excel:

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

Tụkwasị na nke a ị nwere ike ịhụ Koodu maka nyocha dịka:

• Ngụkọta usoro
• Obere
• Ebe nhazi ebe site na otu ebe na ebu
• Ụzọ nyocha
• Ngbanwe n'etiti ogo / nkeji / sekọnd na ogo ogo

Were anya, data ahụ bara uru maka ndị na-azụlite ngwa weebụ, n'ihi na ederela ya koodu
