geo-quadkey-rs

geo-quadkey-rs is a Rust library for encoding and decoding geographical coordinates to and from QuadKeys, a tiling approach used by Microsoft’s Bing Maps Tile System for interactive mapping solutions.

*Source: Microsoft Bing Maps Tile System

I referenced this repository made in Ruby was very helpful in creating this library: deg84/quadkey

Usage

Include geo-quadkey-rs in your Cargo.toml:

[dependencies]
geo-quadkey-rs = "0.1.0"

Then include it in your code:

extern crate geo_quadkey_rs;

use geo_quadkey_rs::Quadkey;

// Encode coordinates to a quadkey
let quadkey = Quadkey::encode(47.60357, -122.32945, 23);

// Decode a quadkey to coordinates
let (latitude, longitude, precision) = Quadkey::decode("12022001101101100101102");

// Find neighbors of a quadkey
let neighbors = Quadkey::neighbors("12022001101101100101102");

Functions

The Quadkey struct provides the following methods:

• encode(latitude: f64, longitude: f64, precision: usize) -> String
• decode(quadkey: &str) -> (f64, f64, usize)
• neighbors(quadkey: &str) -> Vec<String>
• clip(n: f64, min_value: f64, max_value: f64) -> f64
• map_size(precision: usize) -> f64
• ground_resolution(latitude: f64, precision: usize) -> f64
• coordinates_to_pixel(latitude: f64, longitude: f64, precision: usize) -> (i32, i32)
• pixel_to_coordinates(pixel_x: i32, pixel_y: i32, precision: usize) -> (f64, f64)
• pixel_to_tile(pixel_x: i32, pixel_y: i32) -> (i32, i32)
• tile_to_pixel(tile_x: i32, tile_y: i32) -> (i32, i32)
• tile_to_quadkey(tile_x: i32, tile_y: i32, precision: usize) -> String
• quadkey_to_tile(quadkey: &str) -> (i32, i32, usize)
