[OSM-dev] Distance Grid
Hi there, I want to start a project in Brazil that is similar to the Tiger Fixup 250 Cities [1], and I looking forward to build a script that generates a distance grid, like this: http://matt.sandbox.cloudmade.com/usa-routes.html I've tried to contact the authors via wiki, but I was unsuccessful, so I want to develop it by myself. I'm not a professional programmer, but I have some experience in java. Is the LibOSM the easiest way tool to implement it? Thanks, Vitor [1] http://wiki.openstreetmap.org/wiki/TIGER_fixup/250_cities ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

By default MySQL treats all comparisons on varchars as case insensitive.
mysql create table blah ( `k` varchar(255) NOT NULL default '',
primary key (k));
Query OK, 0 rows affected (0.00 sec)
mysql insert into blah values ('hellO');
Query OK, 1 row affected (0.00 sec)
mysql select * from blah where k='hello';
+---+
| k |
+---+
| hellO |
+---+
1 row in set (0.02 sec)
The exception would be if your default collation is binary (which
would have the same side-effect as to making your sorts bunch all the
capital letters together and all the lowercase letters together).
If you need to sort 'H' next to 'h', but don't want to treat 'H' as
equal to 'h', you need to use a database other than MySQL.

Re: [OSM-dev] Distance Grid
No, I don't have the script to generate the cute html... :) By now, we will start with the capitals and some other important cities (30-35 cities), but your script will be necessary in the future, when we raise the number of the cities.

sorry you missed us on the wiki. i have to say, i don't really check

the script is very simple, and uses cloudmade's ruby API [1] to get
the routes. you'll need to sign up for a cloudmade API key, if you
haven't already. the script i've attached will output CSV on stdout,
but i usually put them in a database for easy access.
run it like ruby routes.rb conf file. i've attached an example
configuration file, which is just a yaml map of string to lat/lon
array.
i look forward to seeing brazil's 250 cities :-)
I made a hacky script to generate .yml from XAPI output (attached):
wget
'http://www.informationfreeway.org/api/0.6/node[place=city|town|village|hamlet][bbox=-25.74085,62.84553,-12.41708,67.50085]'
-O iceland-places.osm
perl -CI place2yaml.pl place.osm place.yml
But I just get internal server errors from the CM API:
$ ruby routes.rb place.yml

status: #Net::HTTPInternalServerError:0xb769348c, retrying...
interesting. if you could send me a trace of what's going on that
would be very helpful.
Silly me, I was generating an invalid YAML file. still this could use
a better error message:

Anyway do you have a script to generate that cute HTML matrix? And how
can I link to a route on CM's website. I have to supply lat/lon/zoom
it seems and not just starting/ending lat/lon (at least the URLs I've

i've just thrown something together here - might be buggy, etc...
you'll need to play with the factor variable to see what looks right
for your area.
Sweet, I'll try it out.

[OSM-dev] Code works on sandbox API, doesn't work on main API
I've posted this on the forum also (

have better luck asking here.

Hello,
I wrote a small PHP script to import all the Romanian settlement boundaries
and it is working perfectly fine on api06.dev.openstreetmap.org. However
when I switched to api.openstreetmap.org I keep getting bad request errors.
Here's the code that creates a changeset.
$server = 'api.openstreetmap.org';
$put_file = fopen('tmp/tmpfile', 'w+');
fwrite($put_file, $create_changeset_data);
rewind($put_file);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://
'.$server.'/api/0.6/changeset/create');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_INFILE, $put_file);
curl_setopt($ch, CURLOPT_USERPWD, $user.':'.$password);
$changeset_id = curl_exec($ch);
curl_close($ch);
fclose($put_file);
In $create_changeset_data I have the following:
osm
changeset
tag k=created_by v=Romanian Settlement Boundaries v0.1/
tag k=comment v=Boundaries for Bicaz / Source: Mircea Angelescu
(cultura.ro)/
/changeset
/osm
The provided user / password combination works and I can write tmp/tmpfile.
The error I'm getting (including headers) is here:
http://pastebin.com/m40669009
As I said, if I change $server to api06.dev.openstreetmap.org it works fine.
I don't get it, isn't the sandbox supposed to be exactly the same as the
main API? What's the use of it if it's not? :(
Regards,
Janos
