global_digital_address

Square-cell Web Mercator encoder/decoder for globally unique grid codes (6×6 subdivision per level).

Features

• Web Mercator (EPSG:3857) math with MAX_LAT = 85.05112878°
• Deterministic 6×6 symbol grid per level
• Grouping: AAAA-BBBB-CC for 10-char codes; otherwise groups of 4
• Reverse decode to cell center
• Approximate cell size by code length

Install

# Cargo.toml
[dependencies]
global_digital_address = "1.0"

Usage

use global_digital_address::{get_digi_pin, get_lat_lng_from_digipin};

let code = get_digi_pin(28.6139, 77.2090, 10).unwrap();
let center = get_lat_lng_from_digipin(&code).unwrap();
println!("{code} -> {}, {}", center.latitude, center.longitude);

CLI example

cargo run --example encode_decode
