GeoJSON bbox kaunsa coordinate order leta hai?

West, south, east, north — yaani minimum longitude, minimum latitude, maximum longitude, maximum latitude. GeoJSON har jagah longitude ko latitude se pehle rakhta hai, bolne ke riwaaz ke ulta.

Meri map library bbox alag order mein kyun maangti hai?

Leaflet, Google Maps aur kai aur latitude pehle lete hain kyunki coordinates aise hi bole-likhe jaate hain. GeoJSON geometry ka x-phir-y riwaaz maanta hai. Yahan dono orders milte hain, jo fit ho copy kariye.

Polygon ka area kaise napta hai?

Madhya Earth radius ke sphere par spherical excess formula se, jo poles ki taraf longitude lines ke simatne ko ginta hai. Interior rings ghatti hain, to holes waala polygon apna net area batata hai.

Kya mera GeoJSON naapne ke liye upload hota hai?

Nahin. Document aapke browser mein parse aur naapa jaata hai, to sambhavtah samvedansheel location data kabhi network par nahin jaata.

GeoJSON Bounding Box

Kisi bhi GeoJSON ka bounding box, centre, area aur length — dono coordinate orders mein, sphere par napa.

GeoJSON Bounding Box poori tarah aapke browser mein chalta hai. Paste kiya GeoJSON aapke device par parse hota hai aur kabhi upload nahin hota.

GeoJSON Bounding Box ke baare mein

GeoJSON Bounding Box koi bhi GeoJSON padhta hai — Feature, FeatureCollection, nangi geometry, GeometryCollection ya seedha coordinate array — aur wo chaar numbers deta hai jo use gherte hain. Ye numbers jaan-boojh kar do baar dikhte hain. RFC 7946 GeoJSON bbox ka order west, south, east, north batata hai — longitude pehle — jabki Leaflet aur kai mapping APIs south, west, north, east maangti hain — latitude pehle. Inko milaana galat hemisphere dekhne ke sabse aam raaston mein se hai. Polygon area aur line length flat lat/lng plane ki jagah sphere par napte hain, kyunki degrees ko grid maanna equator se door area ko kaafi badha-chadha deta hai.

Features

Features, FeatureCollections, geometries aur coordinate arrays padhta hai
bbox GeoJSON aur lat/lng dono orders mein deta hai
Box paste-ready GeoJSON Feature ke roop mein bhi
Box ka centre latitude aur longitude mein
Box ki width aur height asli zameeni doori mein
Polygon ka spherical area, holes ghata kar

GeoJSON Bounding Box kaise use karein

Apna GeoJSON paste kariye, ya output ka format dekhne ke liye sample load kariye
West, south, east aur north bounds padhiye
Aapki library jo order maangti hai usme bbox copy kariye
Box ko map par banana ho to polygon output istemal kariye

Example

Input

{"type":"Polygon","coordinates":[[[-0.1757,51.5073],[-0.1502,51.5073],[-0.1502,51.5122],[-0.1757,51.5122],[-0.1757,51.5073]]]}

Output

[-0.1757, 51.5073, -0.1502, 51.5122]

GeoJSON order mein longitude pehle aata hai — lagbhag har map library ke ulta.

Common errors aur troubleshooting

Map box galat jagah bana raha hai. — Lagbhag pakka coordinate order galat hai. Leaflet ka fitBounds latitude pehle maangta hai; GeoJSON ki bbox property longitude pehle. Isiliye yahan dono alag-alag dikhte hain.
Area planar hisaab se kaafi kam hai. — Spherical figure hi sahi hai. Ek degree longitude equator par 111 km hai par London mein sirf 78 — degrees ko ek jaisi grid maanna oonchi latitudes par area phula deta hai.
JSON parse hua par coordinates nahin mile. — Structure mein kahin coordinates array nahin hai. Dekhiye features mein geometry object hai ya sirf properties — aisa tab hota hai jab export geometry column kho deta hai.
