A data scraper that writes the longitude and latitude of the International Space Station to an InfluxDB instance.
Assuming you have the Go programming language installed on your machine, you can run the following commands to install the iss executable on your machine:
git clone git@github.com:scbrickley/iss.gitcd issgo build && go install
Here's an example of how to use the iss command line tool:
iss -url=localhost:9999 -auth=../path/to/auth/file -org=<name-of-org> -bucket=<name-of-bucket>
Once you run that command, iss will start querying the data about once per second. It will then format the data as line protocol and save it to a buffer. Once it has collected 100 data points, it will make the POST request to the write API of the InfluxDB instance you've specified, clear its buffer, and start collecting data again.
If you have geo-temporal features available on your InfluxDB instance, then you can draw these data points to a world map by selecting the Map visualization, selecting Circle map as the visualization type, and creating a query with the following Flux script:
import "experimental/geo"
from(bucket: "ISS")
|> range(start: -2h)
|> filter(fn: (r) => r["_measurement"] == "iss_position")
|> geo.shapeData(latField: "latitude", lonField: "longitude", level: 10)
