Point in Polygon Checker

GeoJSON polygon aur coordinate list daaliye aur dekhiye kaunse point andar aate hain.

Point in Polygon Checker poori tarah aapke browser mein chalta hai. Boundary aur coordinates aksar sanvedansheel location data hote hain aur yahan aapke device par hi rehte hain.

Point in Polygon Checker ke baare mein

Koi coordinate kisi shape ke andar hai ya nahi — yahi sawaal har geofence, delivery zone aur catchment area ke peeche hota hai, aur isme galti aasani se ho jaati hai. Ye tool GeoJSON document ke har polygon par even-odd ray cast chalata hai aur har point ko andar, bahar ya theek boundary par bata deta hai. Interior ring wahi karte hain jo specification kehti hai: hole ke andar wala point bahar ginaa jaata hai. Coordinates aap waise likh sakte hain jaise log likhte hain, latitude pehle, ya GeoJSON wale longitude-pehle kram mein.

Features

  • Polygon, MultiPolygon, Feature, FeatureCollection aur GeometryCollection padhta hai
  • Holes ghata deta hai: interior ring ka point bahar ginaa jaata hai
  • Boundary par baithe point alag dikhte hain, tolerance badla ja sakta hai
  • lat/lng ya lng/lat kram, saath hi WKT POINT aur geo: URI
  • Poori list ek saath test karta hai aur milne wale shape ka naam deta hai
  • N, S, E, W akshar declare kiye gaye kram par bhaari padte hain
  • Nateeje GeoJSON mein export, har feature par faisla ke saath

Point in Polygon Checker kaise use karein

  1. Wo polygon ya FeatureCollection paste kijiye jiske against test karna hai
  2. Jaanchne wale coordinates daaliye, har line par ek
  3. Batayiye ki aapke coordinates latitude pehle hain ya longitude pehle
  4. Har point ka faisla padhiye aur zaroorat ho to GeoJSON export kijiye

Example

Input

51.5074, -0.1278

Output

inside — Central London

Har point us naamit feature ko bata deta hai jisme wo hai, isliye overlapping zone alag pehchane jaate hain.

Common errors aur troubleshooting

  • Saare point bahar dikh rahe hain. — Coordinate order lagbhag pakka ulta hai. GeoJSON longitude pehle rakhta hai jabki log latitude pehle likhte hain — toggle badliye aur nateeja palat jaayega.
  • Andar hona chahiye tha par boundary dikh raha hai. — Round kiye gaye coordinates kinare se baal bhar door girte hain. Edge tolerance badhaiye ya point ki poori precision istemal kijiye.
  • Document mein koi polygon nahi mila. — Sirf Polygon aur MultiPolygon geometry kisi point ko rakh sakti hai. Line ya point layer mein test karne ko kuchh nahi hota.
  • Shape ke andar ka point bahar dikh raha hai. — Dekhiye ki wo kisi hole mein to nahi. Pehle ke baad wale ring interior hote hain aur specification unhe kata hua maanti hai.

Aksar pooche jaane wale sawaal

Point in polygon test kaam kaise karta hai?
Point se ek ray chhodi jaati hai aur girne wale kinare gine jaate hain. Vishem sankhya matlab andar, kyunki har crossing andar-bahar badalta hai. Holes isi niyam se nikal aate hain.
Kya ye antimeridian paar karne wale polygon sambhalta hai?
Tabhi jab polygon 180 degree par pehle se bataa hua ho, jaisa RFC 7946 kehta hai. ±180 se aage ke coordinates waise hi test hote hain jaise likhe hain.
Theek kinare par baithe point ka kya hota hai?
Use boundary hit bataya jaata hai, kisi taraf zabardasti nahi kiya jaata, kyunki wahan jawab convention ka hai geometry ka nahi. Tolerance tay karti hai ki kinara kya maana jaaye.
Kya main sau se zyada coordinates ek saath jaanch sakta hoon?
Haan. Har line document ke har polygon ke against test hoti hai aur table milne wale shape ka naam deti hai. Sab page mein hi hota hai, isliye lambi list bhi tez rehti hai.
Kya ye poore desh ya mahadweep ke liye bharosemand hai?
Test latitude-longitude plane par hota hai aur andar-bahar ke sawaal ke liye theek hai, jab tak kinare un coordinates mein seedhe maane jaayein — yahi GeoJSON khud maanta hai.
