Bangkok District Geocoding

A lightweight library to find the Bangkok district based on latitude and longitude coordinates.

Features

• Fast and Efficient: Quickly find a district from geographic coordinates.
• Offline: No network requests needed; all data is included in the package.
• TypeScript Support: Fully typed for a better development experience.

Data Source

The geographic data for Bangkok's 50 districts is sourced from the official Open Government Data of Bangkok website:

• Source: พื้นที่เขตปกครอง 50 เขตของกรุงเทพมหานคร

The original data was provided in Shapefile format and was converted to GeoJSON using mygeodata.cloud.

pnpm install bkk-district-geocoding
# or
npm install bkk-district-geocoding
