having the right to download images is not at all the same thing
as, for example, having access to ip/cookies/timestamp
and a great deep learning database.

for some people, contributing to increasing FB profiling,
even with a open license, is not the same thing as contributing
to a open license database not owned by a gafam member.

Serious funding?  Yes.  Outrageous funding?  No.

Rough estimate:

* The CIA World Factbook says there are about 64 000 000 km of roads in
  the world.
* Google Street View takes 100 photos per km.
* A photosphere from my tablet, compressed using WebP at 50% quality
  takes 2.7 MB.

This is about 17 280 TB of storage to cover the entire world at Google
Street View quality.  It would cost $215 000 per month to store in
Amazon S3, or $89 000 per month in Backblaze B2.  It's well within the
capacity of someone like the Wikimedia Foundation.

Very little.

Were you not aware that your contributions to OSM, and Mapilary, are
already under an open licence, which allows anyone - including
Facebook - to reuse them, even commercially?

Re: [OSM-talk] Facebook acquires crowdsourced mapping company Mapillary

[Nick Whitelegg]

Hello Florian,

Yes - I have to admit that's partly why I've been focusing on walking trails 
only in my own project (aside from the fact that I have a particular interest 
in waling trails), the storage requirements are not going to ramp up so quickly.

I have to admit I haven't considered how exactly a fully open source StreetView 
would be funded - other people would be better-placed than myself to think of 
solutions to this - but was just floating the idea as a nice-to-have.

Nick

The issue is that once you start pushing stuff into any projects your
storage expenses will kill you pretty fast.

https://www.backblaze.com/b2/cloud-storage-pricing.html

Thats 0.005$ per GB and Month. Thats *12 *1024 for a Terrabyte. Thats
something like 60$ per Year per Terrabyte which sounds reasonable
concerning disk costs. Costs per disk per lifetime and infrastructure to
connect it to the IP Network.

Since late May i have produced:

flo@p4:/scratch/local/mapillary$ du -sh .
285G.
flo@p4:/scratch/local/mapillary$ find . -type f -iname "*.jpg" | wc -l
97407

So just pushing worth like 2 Weeks of taking street imagery will cost the
Hoster about 20$ per year from now on. And i have pushed multiple terrabytes
to Mapillary since 2014.

And thats just me. Put that to a global OSM perspective and you need
serious funding for storing all that imagery, let alone the CPU cycles
for your compute vision to blur faces and number plates.

And as i have done something like OpenStreetcam 10 years ago for my personal
imagery without the fancy blurring stuff. And i have worked for Hosting
companys so i know the deal.

This is why I think personally that the Facebook deal is the only
viable option for getting long term funding for storage. Somebody
has to pay for it. And i dont see a real businesscase which will pay
up for all the random Dashboards people store into your Dataset.

So either Facebook supports this service or we are toast.

The only option would then be OSMF funding but you may have a glimpse
at the Mapillary numbers and prepare some fundraising.
