A binary XML format would be better to parse for an XML processor. But OSM
data is pretty structured. The point is that for line transfers a pretty
efficient format can be choosen that is totally unparsible by embedded
devices.
The actual transfer is pretty much irrelevant here. The goal

Invent the following format. mmap your program structures to a file, sync

Hi,
I was considering volunteering some of my machines for tiles at home,
but the readme told me that it required up to a gigabyte of RAM.
As Linux doesn't allow me to tell the OS to only run that program if
I don't need the RAM for other stuff, that's just too much, so I can't
participate.
I am working with OSM data, and would like to be able to spec out 5 mile
bounding boxes from certain GPS points.
After research into this problem, I am to understand that each degree of
latitude is approximately 69 miles (111 kilometers) apart with a slight
variance (68.703 - 69.407 miles)

Since all of these calculations are planar and near estimates, perhaps
it would be good to use libraries that particularly cope with
geospatial operations
perhaps GOES might be a good starting point:

Hi Rogier, I wanted to try this forumla out.
Could you possibly help me by spelling out the formula in more word
terms, like
i.e. Take initial latitude number, and divide it by X then divide that by
the cosign of the XX ... which should result in XYZ
something like that. Basically I hope to
