About

This will pull in thousands of weather observations from around the world as semantic data. It will also check every minute for updates.

Data Source

• Observations are pulled from NOAA here.
• Station metadata is pulled from NOAA here.

Raw Data

Data can be pulled from METAR without IOTDB adding semantic structure. See connect.js for an example.

• Read about installing Home☆Star

Then:

$ npm install -g homestar    ## may require sudo
$ npm install homestar-metar

The configure command simply pulls down all the station metadata. There is no user interaction required

Use

Get everything

const iotdb = require("iotdb")
iotdb.use("homestar-metar")

const things = iotdb.connect("MetarObservation")
things.on("istate", function(thing) {
    console.log(thing.state("istate"));
});

Get one specific station

const things = iotdb.connect("MetarObservation", {
    station: "CYYZ",
})

Get set of stations

const things = iotdb.connect("MetarObservation", {
    station: "C???",
})
