README
This package provides polygons/multipolygons for all countries and their sub-divisions from the [GADM dataset](https://gadm.org/).
It fetches the data dynamically from the officially hosted database using [DataDeps.jl](https://github.com/oxinabox/DataDeps.jl).
## Installation
Get the latest stable release with Julia's package manager:
```julia
] add GADM
```
## Usage
`GADM.get` returns polygons/multipolygons, which implement the [GeoInterface](https://github.com/JuliaGeo/GeoInterface.jl):
```julia
import GADM
# GADM.get(, , , , ...)
# get boundary of the country India
india = GADM.get("IND")
# get boundary of the state/province Uttar Pradesh in India
uttar = GADM.get("IND", "Uttar Pradesh")
# get boundary of the district Lucknow in Uttar Pradesh, India
lucknow = GADM.get("IND", "Uttar Pradesh", "Lucknow")
```
The option `depth=n` can be used to return a table of polygons for all subregions at depth `n`:
```julia
states = GADM.get("BRA", depth=1)
cities = GADM.get("BRA", depth=2)
```
- **Country Code** follows the ISO 3166 Alpha 3 standard, you can find the code for your country [here](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3).
- Other regions require "approximately" official names that are at least contained (case-insensitive) in the official name.
The coordinate reference system is longitude/latitude and the WGS84 datum.
## Credits
GADM, the Database of Global Administrative Areas, is a high-resolution database of country administrative areas, with a goal of "all countries, at all levels, at any time period." The database is available in a few export formats, including shapefiles that are used in most common GIS applications.
