Yes, OSM is very resource hungry. I've done a lot of work on the
OpenStreetMap data and think I have mapping all set for this
project. <br>
<br>
I actually got the entire map rendering stack set up and running on
the ARM wireless harddrive, but it was hopelessly slow (2-5 minutes
to render each tile).<br>
<br>
So I ended up using about a month of processing time on my server to
pre-render the entire globe to 30 ft resolution, and then scripted
up rendering of populated places to 15 ft resolution. Ends up
taking only about 130GB for the tile images (vs the 350GB for the
actual database, which seems wrong).<br>
<br>
By the end I had bought a second computer with 16GB RAM and a 500 GB
SSD just so it could handle the OSM dataset. (helps with the
Wikipedia dataset too).<br>

<div>map data, which takes a lot of resources just to hold (like
300GB for the whole world). If you pre-rendered the tiles I
suspect it'd be even bigger.<br>

Your project sounds cool tho! If there's a code repo, I'd like
the link!<br>

<br>
For months I've been spending spare time on my
Internet-in-a-Box project. There is still a lot to do, and
I was wondering if anyone wants to volunteer to help.<br>
<br>
The concept:<br>
Convert a Seagate GoFlex Satellite wireless harddrive
(possibly solar powered) into a portable offline "internet"
hotspot with most(?) of the world's Free knowledge and
information. Ship to schools and villages in the developing
world (I have contacts from my old Wikipedia Reader
project). Accessible via low end smart phone, tablet, or
PC.<br>
<br>
I am aiming to provide:<br>
<br>
-World-wide maps down to street level (OpenStreetMap)<br>
<br>
-Complete Wikipedia in a dozen languages<br>
<br>
-Tens of thousands of Project Gutenberg texts in multiple
languages<br>
<br>
-Most of the world's Open Source software - complete Ubuntu
repository mirrors including source code.<br>
<br>
-Hundreds of hours of Khan Academy instructional videos (CC)<br>
<br>
-More?<br>
<br>
<br>
Many things remain to be done, for example:<br>
<br>
-Evaluate and integrate a faster Wikipedia solution which
can work well on the (slow) Satellite (128MB RAM ARM)<br>
-A mobile-friendly Project Gutenberg browser<br>
-A mobile-friendly video browser<br>
-A mobile-friendly Open Source software browser<br>
-Cross-domain search functionality and content indexing<br>
-More?<br>
<br>
Platform is a chroot ARM Debian on the Satellite using
Python and Flask as glue.<br>
<br>
I'm determined to have this ready to go by April.<br>
<br>
thanks,<br>
