[OSM-talk] Comments On New Tile Layer Guideline Process

Hi,

This is the wiki document that contains the process for adding new
tile layers to the main osm page.

Here is the process.

http://wiki.openstreetmap.org/wiki/Strategic_working_group/New_Tile_Layer_Guidelines

- Global scope and coverage

Why does this requirement exist? As an example, if we put a winter
sports layer up, do we really need to render a map where it does not
snow? Covering everything makes sense for many layers, but the process
document has this as a requirements. You could also conceive of
situations where showing a broken/poor map rendering could be used to
rally people to action. For example, don't like the satellite images
for you area, go bang on your local government and get the images
released.

- Unique, Interesting

The strategic working group goes into a closed room and has a secrete
ballet to vote and decides on these two items.

For example, current transportation map  and the
http://xn--pnvkarte-m4a.de map are kind of close the decision was made
to drop http://xn--pnvkarte-m4a.de. However, having reviewed
http://xn--pnvkarte-m4a.de in my area, I am certain that
http://xn--pnvkarte-m4a.de is far better than our transportation map
for public transportation. For everybody that is mapping train
stations and bus stops, they should be looking at
http://xn--pnvkarte-m4a.de to figure out the best tagging, because our
default transportation map is doing it wrong. It would not be a big
deal if we had both layers available. By not using both, I am certain
our mapping for public transit is worse off.

We actually have another major software group in OSM that has a
similar problem. JOSM! I know what you thinking. It is not fair to
compare osm.org and JOSM. JOSM is written by a bunch of hippie
Germans. They are well know for disliking process and truly enjoy
anarchy. Keeping that in mind, If you want to add an image layer to
JOSM, you go and edit a wiki page and add your url + boundary shape.
No two page process document, no closed door meeting, no secrete
ballets. You know what has happened? I have 6 unique and interesting
layers available where I map. It just seemed to work out somehow.

The list of default map layers is *content*. Just like the map, just
like the wiki, just like the diary entries, etc. It is completely
inappropriate for the computer system administrators of the osm web
server to be sitting behind closed door and making these kinds of
decisions for everybody. If same process was used to make changes to
the actual map data, it would be seen as clearly out of bounds.
osm.org is not medical or avionics software. If there is a broken map
layer, it is really not that big of a deal, life will go on. The rest
of the osm.org site will continue to function. This heavy process is
simply not needed.

This is what the process should be.

- Make is so we can use smaller map layers.
- do a license check on the tiles + data. Obviously, it needs to be an
OSM based map.
- make sure it is up to date and syncing with our diffs,
- make sure it actually works
- stick it in

- if is breaks, take it out.
- If nobody uses take it out.
- If you get too many, figure out what to take out on this list. For
the record, this would be a good problem to have.

The strategic working group is out of bounds on this issue and needs
to get out of way. I am certain this heavy process is hurting the
project.

Thanks
Jason.
