mysql-apidb06.sql schema changes; prefix relation to id fields 9 years ago


This project enables the use of Osmosis (Github) to import (an extract of) the planet.osm using OSM 0.6 API into a MySQL database.

The support officially has been dropped, but I needed a MySQL compatible representation of the data.

I found an (the?) old mysql schema on Brett Henderson's Homepage and started from there. If you are interested in the changes I made, take a look into the problems and the history of git repository.

Import planet.osm.bz2 into a MySQL Database

Install Omosis

$ brew install osmosis

Install MySQL

$ brew install mysql
$ unset TMPDIR
$ mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
$ mysql.server start
$ /usr/local/opt/mysql/bin/mysql_secure_installation

We follow the naming scheme in the script and create database and user accordingly

$ mysql -u root -p
mysql> CREATE DATABASE api06_test;
mysql> GRANT ALL PRIVILEGES ON api06_test.* TO osm@localhost IDENTIFIED BY 'osm';
mysql > exit;

Get the latest version of my mysql schema script based on Brett Henderson's work

$ wget

Create the schema using the sql script

mysql -u osm -p -h localhost api06_test < mysql-apidb06.sql

Read data and populate database

osmosis --read-xml file="bremen.osm.bz2" --write-apidb-0.6 host="" dbType="mysql" database="api06_test" user="osm" password="osm" validateSchemaVersion=no


Return all main streets in a bounding box

select w.`id`, w.sequence_id, latitude, longitude, t1.v as name, t2.v as type
from current_way_nodes w, current_nodes n, current_way_tags t1, current_way_tags t2
where w.`node_id` = n.`id`
and w.`id` = t1.`way_id`
and w.`id` = t2.`way_id`
and t1.k = 'name'
and t1.v <>  ''
and t2.k = 'highway'
and t2.v in ('primary', 'secondary', 'tertiary', 'motorway', 'residential', 'road', 'track', 'trunk')
and n.latitude > 53 * 10000000
and n.latitude < 54 * 10000000
and n.longitude > 8 * 10000000
and n.longitude < 9 * 10000000
order by w.`id` asc, w.sequence_id asc;

OSM uses Fixed Precision Integer for the geographical location. Instead of persisting 53,0749415 as a floating point number in the database, it will be persisted as 530749415. The precision of the floating point number is defined as 7 decimal places, so you have to multiply or divide with 10^7.
