What does it do?
Given a location and a date, it uses the Nasa Earth API to show a photo taken by the Landsat 8 satellite. The script must be executed on the command-line.
Setup
Before using the script, you must have access to the Nasa’s API key. You can quickly get a key at https://api.nasa.gov/.
After that, save your key as an environment variable called NASA_API_KEY. Then, you are good to go.
How to use
In the same directory where the script is saved, run the following code on the command-line:
get_image.py -LAT [latitude] -LON [longitude] -DATE [date] -DIM [dimension] –info
-DATE, -DIM and –info are optional. -DATE defaults to today. -DIM defaults to 0.15.
If –info is provided, then the latitude and longitude you input are written onto the image.
Note
If the image can not be retrieved, chances are the coordinates are in the ocean. Ocean images do not seem to be kept saved in the Landsat 8’s database.
