A web based tool for making MapLibre GL maps with data from sources such as Overpass, GeoJSON, GPX, KML, TCX, etc

In order to allow for querying Overpass with the extents of the MapLibre viewport, Ultra
replaces any occurences of `{{bbox}}` in the query with the bounding box in the format expected by
the Overpass API.

For example:

```
[bbox:{{bbox}}];
nwr[shop];
out center;
```

### Other formats

If you need to specify your bounding box in a different format, for example for an HTTP GeoJSON API
or [Postpass](https://github.com/wookdpeck/postpass), you can specify just the specific lat/lon
vaulues or a comma-delimited set of values.

#### Short form

The short form is wrapped it double curly braces and consists of a string of one or more of the
letters `n`/`s`/`e`/`w` which corespond to the north/south-most latitudes and east/west-most
longitudes.

This means you can use simple 1-character shortcuts like:

- `{{s}}`
- `{{n}}`
- `{{e}}`
- `{{w}}`

Or a longer string like `{{wsen}}` which is equivalent to `{{w}}{{s}}{{e}}{{n}}`.

[Example](./Examples/alt-bbox-format.md)

#### Long form

The original long form of he individual min and max of both latitude and longitude are also
available:

- `{{south}}`
- `{{north}}`
- `{{east}}`
- `{{west}}`
