# Triglav

A web for helping out with editing OSM.

Check it out here:
https://triglav.bezdomni.net/

## Prerequisites

* Elixir 1.11 with Erlang/OTP 23
* PostgreSQL 13 with PostGIS 3.1
* osm2pgsql 1.4.0

May work with other versions, but these are tested.

## Quick start

```ex
# Define where the database is located
export DATABASE_URL=ecto://user:pass@localhost:5432/triglav_dev

# Install elixir dependencies
mix deps.get

# Install node dependancies
npm install --prefix assets

# Initialize the database
mix ecto.create
mix ecto.migrate

# Import GTFS data from zet.hr
mix triglav.import_zet

# Import OSM data for Croatia from Geofabrik
mix triglav.osmosis_init

# Start server
mix phx.server
```

The web is hopefully available at http://localhost:4000/
