[Landsat-pds] Converting MTL.txt to JSON

[Layton, Jeff]

Charlie,

Right now the script just reads the MTL file as a string and writes it the exact same way it reads it. We can convert the string to a number, then change how we write it but it will take a little work. My suggestion is to write out the JSON file exactly as the MTL file is written so they match and there's no difference between the two. Does this work?

Thanks!

Jeff

Hi all,

Hurray, JSON! Thanks, Jeff!

It’s just a detail, but should the numeric values be converted to numbers? For example, this line of JSON:

>            "REFLECTANCE_MULT_BAND_9": "2.0000E-05",

could be replaced by:

>             "REFLECTANCE_MULT_BAND_9": 2e-05,

This would mean one less conversion-and-check necessary on the end user’s side in order to use the value.

I won’t push on this – it’s a very small thing and it might add complexity in ways I’m not seeing. Just asking.
