I am using a R package for downloading MODIS data.

It is giving error as

the http address does not exist! Version may be incorrect OR Server is down!

Interestingly version is correct, and I can excess the site which is a data repository that shows server is not down.

The URL which this R package is trying to access is 'https://e4ftl01.cr.usgs.gov/MOTA/MCD43A3.006/'

Though the URL exist, when I check it as

u = 'https://e4ftl01.cr.usgs.gov/MOTA/MCD43A3.006/'
if (!url.exists(u)) print('URL does not exist')


[1] "URL does not exist"

What could be the reason for this error?

  • `url.exists('https://e4ftl01.cr.usgs.gov/MOTA/MCD43A3.006/')` gives TRUE to me..and this doesn't print anything `if (!url.exists('https://e4ftl01.cr.usgs.gov/MOTA/MCD43A3.006/')) print('URL does not exist')` – Ronak Shah Aug 10 '18 at 04:59
