Map to get METAR information for airports by clicking on them.

A working installation is now hosted at http://metar.codeforbonn.de/

Currently there are:

• several node scripts that fetch data to be used and convert it into JSON
• a node script that puts the data together to generate the geoJSON
• a map that uses leaflet to display the airports

To create the web page that links the METAR data

1. clone this project (favourably using git clone)
2. change into the project's directory
3. install all required packages using npm install
4. issue npm run publish

These steps will obtain all the packages and data needed (a couple of MB), process the data and generate a subdirectory named website containing a website displaying all the airports for which a location is available and for which the availability of METAR information has been confirmed (said METAR information may however be outdated).

Due to browser security settings you will not be able to open the website using a file:// url, it needs to be served by a web server. This web server needs to PHP support because accessing tgftp.nws.noaa.gov qualifies as cross site scripting and hence requires a. The one I use is written in PHP because that's the language supported by most hosters.

Anyway, if you move the mouse over a marker you see a tooltip with the airport's name as well as its ICAO code, the location (nearby city or similar) and in which country it is located as illustrated below:

Clicking on one of the markers opens a popup that initally shows some static information about the airport to which METAR data is added as soon as it has been fetched. Currently the following is provided:

• Pressure
• Temperature
• Dew Point
• Visibility

As long as parsing is work in progress the raw METAR data is shown as well.

package.json contains a number of tasks that allow you to only update what really needs to be updated - see the following diagram: The task names are verbose to make it obvious what the individual tasks are good for.
