Downloading multiple octants?

[ljarasunas2021]

Hello,

First off I will say that this is a great plugin - definitely the best I have found online. I was wondering if it is possible to download more than one octant at a time? Is this related to LexSong's script? If so I received this error when running it -

File "find_overlaps.py", line 10 URL_PREFIX = f"https://kh.google.com/rt/{PLANET}/" ^ SyntaxError: invalid syntax

If that is not the case - don't worry about the error. All that I'm trying to do is to download multiple octants at the same time. Thank you in advance!!!

downloading multiple octants works using the dump_obj script

you can do

node dump_obj.js 3060417360436156121 3060417360436156123 3060417360436156130 3060417360436156131 3060417360436156301 3060417360436156311 20

for example

in regards to your error in the .py script you might be using an unsupported version? just a guess

Ah thank you! Do you mean an unsupported version of python or of this github repo? Thank you so much!

You might have Python2 which may not work. Try installing Python3

Perfect thank you!

Ok so I downloaded Python3 but obtained this error:

Any ideas on what went wrong?

think you need to run Install Certificates.command. do a search for certifi

There is still one problem, if we download too many octants once, currently the folder name is the concatenation of all octants, which could exceed the max possible filename length and result in an error. There is need to modify line 28 of dump_obj.js to avoid this.

I fixed that folder length issue with the following commit: https://github.com/campmdabt/earth-reverse-engineering/commit/f98bbef183249a872e0d9b32585358d1b76d949b

It limits the number of octants used in the name to 4.
