The source data for this application is maintained by the National Weather Service under the umbrella of the National Oceanic and Atmospheric Administration (NOAA).
This is a hobby project and a simple graphical client for the NOAA weather API hosted at weather.gov. This software uses the (excellent) Raylib library with Go bindings to display weather forecast data. The forecast data is rendered to an underlying OpenGL context setup by Raylib.
Go was chosen for its ease of use and robust HTTP support (but also because I already had a NOAA API wrapper handy.)
This project depends on the following external or open source components:
- api.weather.gov (for weather observations)
- raylib, a simple and easy-to-use library to enjoy videogames programming. (For Window creation and ease of rendering)
- Golang bindings for raylib-go
- C/C++ compiler (for
cgo) - ...TBD other for parsing YAML, etc.
Check out raylib and the raylib-go bindings projects for prerequisites and initial setup.
There are two different ways to configure the program to pull in a weather forecast and both options require a latitude and longitude value.
config.yml: The first option is to edit the config.yml file included with this project. The example shown here
points the application at the Chicago, IL weather observations pulling in standard units.
noaa:
latitude: 41.837
longitude: -87.685Then, once you have setup your coordinates you can pass a configuration option to the software such as:
noaawc.exe -config config.yml-lat <latitude> -lon <longitude>: The second option is to pass in the lat and lon arguments when starting the program.
noaawc.exe -lat "41.837" -lon "-87.685"config.yml: If you wish to pull forecast data in Metric units you may pass the "units" parameter in the config file as follows.
noaa:
latitude: 41.837
longitude: -87.685
units: siAlternatively, you can set the units via command line argument such as:
-uom <units>: units can be "si", "us", or not set (defaults to us)
noaawc.exe -uom si
