### What is a QuadKey?

A QuadKey is a string representation of a tile's location in a quadtree hierarchy. It is used to index and address tiles at different levels of detail (zoom levels). The QuadKey system is based on dividing the Earth's surface into quadrants using a quadtree structure.

For more details on the concept, please refer to
the [Microsoft Article About this](https://docs.microsoft.com/en-us/bingmaps/articles/bing-maps-tile-system).

## Installation
### Requirements
   This library requires **Python 3.6** or higher. To compile it from source, Cython is required in addition.

### using pip
```bash
pip install quadkey-boosted
```
### From source
#### Prerequisites (`Linux`)
* `gcc`
    * Fedora: `dnf install @development-tools`
    * Ubuntu / Debian: `apt install build-essential`
* `python3-devel`
    * Fedora: `dnf install python3-devel`
    * Ubuntu / Debian: `apt install python3-dev`

#### Prerequisites (`Windows`)
* Visual C++ Build Tools 2015 (with Windows 10 SDK) (see [here](https://devblogs.microsoft.com/python/unable-to-find-vcvarsall-bat/#i-need-a-package-that-has-no-wheel-what-can-i-do))
#### Build from source
```bash
# Clone  repo
git clone https://github.com/ls-da3m0ns/quadkey-boosted

# Create Virtual Environment
python -m venv ./venv
source venv/bin/activate

# Install dependencies
pip install -r requirements.txt

# Compile 
python setup.py sdist bdist_wheel

# Install 
pip install dist/quadkey-0.0.1-cp38-cp38-linux_x86_64.whl
```
# Usage
## Basic Usage
```python
import quadkey
lat = 47.641268
lng = -122.125679
zoom = 15

# Convert lat lng to quadkey
qk = quadkey.geo_to_quadkey(lat, lng, zoom)

# Convert quadkey to lat lng
## get top left corner
lat, lng = quadkey.quadkey_to_geo(qk, corner=0)
## get bottom right corner
lat, lng = quadkey.quadkey_to_geo(qk, corner=2)

# Convert quadkey to bbox
bbox = quadkey.quadkey_to_bbox(qk)

# Convert quadkey to Tile
tl = quadkey.quadkey_to_tile(qk)

# Conver quadkey to quadint
qi = quadkey.quadkey_to_quadint(qk)

# Convert lat lng to quadint
qi = quadkey.geo_to_quadint(lat, lng, zoom)

# get parent quadkey
parent = quadkey.get_parent(qk)
```
