... Introduction . 1/46 Introduction
.. This slide is for... . Introduction . 2/46 1. Who has map data and wants to provide tile servers 2. Who wants to edit map by using editors such as iD, Potlatch 3. Who is interested in building a local OpenStreetMap
.. OSM Component Overview . Introduction . 3/46
.. What will we do . Introduction . 4/46
.. Contents . Introduction . 5/46 1. Build a tile server 2. Build a website containing map editors, API, and UI 3. Connect two services together
.. Environment . Introduction . 6/46 . VirtualBox VM . Ubuntu 12.04 (32-bit) . Memory: 2GB . Storage: 120GB, . Networks: NAT and Host-only Adapter
.. My settings . Introduction . 7/46 . User: map . Password: 000000 . ssh installed (sudo apt-get install openssh-server) . Basically, you should know how to get the “ip” of your VM (ifconfig, and it looks like “192.168.x.x”) and how to use “ssh” (ssh map@192.168.x.x) . If you get confused, you probably have to google “virtualbox ubuntu install, virtualbox ssh” . If not, good! Let’s move on!

.. Import map data into Postgresql . Build a Tile Server . 24/46 . osm2pgsql --slim -d map -C 1600 --number-processes 2 taiwan-latest.osm.pbf If your osm2pgsql is not version 0.81, you might face errors. pthread_join() returned exception: Throw location unknown (consider using BOOST_THROW_EXCEPTION) Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::current_exception _std_exception_wrapper<std::runtime_error>> std::exception::what: CREATE TABLE planet_osm_point_tmp AS SELECT * FROM planet_osm_point ORDER BY CASE WHEN ST_IsEmpty(way) THEN NULL ELSE ST_GeoHash(ST_Transform(ST_Envelope(way),4326),10) END failed: ERROR: GetProj4StringSPI: Cannot find SRID (4326) in spatial_ref_sy

Build a Tile Server . 25/46 . sudo mkdir /var/run/renderd . sudo chown map /var/run/renderd . renderd -f -c /usr/local/etc/renderd.conf If your used ssh you might face a problem ”locale::facet::_S_create_c_locale name not valid”, just execute the following command before you start tile server export LC_ALL="en_US.UTF-8" Now, open a new terminal and execute . sudo /etc/init.d/apache2 restart
.. Check your tile server . Build a Tile Server . 26/46 Open your browser and go to: http://localhost/osm_tiles/0/0/0.png If you see a picture of world map then the tile server is working. You can stop renderd process by press Ctrl+c (the original terminal) Otherwise, if any error occured, you have to double check all the configurations and install steps. For example, all the config files in folder “src/mapnik-style/inc”, renderd.conf, and others.
.. Create a startup daemon for renderd . Build a Tile Server . 27/46 If everything works well then we are going to create a starup daemon for renderd. . sudo cp ~/src/mod_tile/debian/renderd.init /etc/init.d/renderd . sudo chmod u+x /etc/init.d/renderd . sudo vim /etc/init.d/renderd change these lines and replace “map” to your username DAEMON=/usr/local/bin/$NAME DAEMON_ARGS="-c /usr/local/etc/renderd.conf" RUNASUSER=map . sudo /etc/init.d/renderd start . sudo ln -s /etc/init.d/renderd /etc/rc2.d/S20renderd

.. Check your map . Build a Tile Server . 30/46 Go to: http://192.168.x.x/osm or if you visit from local http://localhost/osm If you were not used map of Taiwan, you should change the initial location (setView([Lag,Lng],7)). Next, we are going to build a map website and provide an editor for users to edit map data by API

Next, on the top-right corner, select “My settings” and click “oauth settings” then “Register your application” Fill “iD” into “Name”, fill “http://192.168.x.x:3000” into “Main Application URL”, and checked “modify the map” in below Click “Register” and copy the “Consumer key”
.. Editor Configuration . Build an OpenStreetMap Website . 38/46 . sudo vim config/application.yml find the “id_key” line, uncomment it and fill the key’ id_key: "VGWM4FlewbJSjLvWbxml5xr45zus8nH0DWKN6yBw" Restart the rail server and go to your website to click “Edit” button (default editor is iD) You will see the iD editor is working.

.. The ”duplicate key” problem . Build an OpenStreetMap Website . 41/46 . psql -d openstreetmap execute the following commands SELECT pg_catalog.SETVAL('acls_id_seq', (SELECT MAX(id) FROM acls)) SELECT pg_catalog.SETVAL('changesets_id_seq', (SELECT MAX(id) FROM changesets )) SELECT pg_catalog.SETVAL('client_applications_id_seq', (SELECT MAX(id) FROM client_applications)) SELECT pg_catalog.SETVAL('current_nodes_id_seq', (SELECT MAX(id) FROM current_nodes)) SELECT pg_catalog.SETVAL('current_relations_id_seq', (SELECT MAX(id) FROM current_relations)) SELECT pg_catalog.SETVAL('current_ways_id_seq', (SELECT MAX(id) FROM current_ways)) SELECT pg_catalog.SETVAL('diary_comments_id_seq', (SELECT MAX(id) FROM diary_comments)) SELECT pg_catalog.SETVAL('diary_entries_id_seq', (SELECT MAX(id) FROM diary_entries)) SELECT pg_catalog.SETVAL('friends_id_seq', (SELECT MAX(id) FROM friends)) SELECT pg_catalog.SETVAL('gpx_file_tags_id_seq', (SELECT MAX(id) FROM gpx_file_tags)) SELECT pg_catalog.SETVAL('gpx_files_id_seq', (SELECT MAX(id) FROM gpx_files)) SELECT pg_catalog.SETVAL('messages_id_seq', (SELECT MAX(id) FROM messages)) SELECT pg_catalog.SETVAL('note_comments_id_seq', (SELECT MAX(id) FROM note_comments)) SELECT pg_catalog.SETVAL('notes_id_seq', (SELECT MAX(id) FROM notes)) SELECT pg_catalog.SETVAL('oauth_nonces_id_seq', (SELECT MAX(id) FROM oauth_nonces)) SELECT pg_catalog.SETVAL('oauth_tokens_id_seq', (SELECT MAX(id) FROM oauth_tokens)) SELECT pg_catalog.SETVAL('redactions_id_seq', (SELECT MAX(id) FROM redactions)) SELECT pg_catalog.SETVAL('user_blocks_id_seq', (SELECT MAX(id) FROM user_blocks)) SELECT pg_catalog.SETVAL('user_roles_id_seq', (SELECT MAX(id) FROM user_roles)) SELECT pg_catalog.SETVAL('user_tokens_id_seq', (SELECT MAX(id) FROM user_tokens)) SELECT pg_catalog.SETVAL('users_id_seq', (SELECT MAX(id) FROM users)) q Now you can use iD to edit your own map.

.. Change Initial Location of Map . Connect Together . 44/46 . sudo vim openstreetmap-website/app/assets/javascripts/osm.js.erb set your initial Location #mapParams.lon = -0.1; mapParams.lon = 120.1204; #mapParams.lat = 51.5; mapParams.lat = 23.0260; #mapParams.zoom = parseInt(params.zoom || 5); mapParams.zoom = parseInt(params.zoom || 10);
.. Update Tile Server . Connect Together . 45/46 . cd . sudo vim update-tile.sh add these commands into it ./src/osmosis-latest/bin/osmosis --read-apidb host="localhost" database="openstreetmap" user="postgres" password="Your Password" validateSchemaVersion="no" --write-xml file=".osm/update.osm" osm2pgsql --slim -d map -C 1600 ./osm/update.osm sudo rm -R /var/lib/mod_tile/default/ sudo /etc/init.d/renderd restart Note: You can execute these commnads separated instead of using shell script. . sudo chmod u+x update-tile.sh . ./update-tile.sh
.. Finally . Connect Together . 46/46 If you see the changes of your map on your tile server then everything is working, congratulations! You can download the draft of all install commands here: https://www.dropbox.com/s/oglhsw57slcsybt/install Or, email me: Marc Huang<marchuang41@gmail.com> if you have any questions.

References . 1. https://switch2osm.org/ This website teaches you how to build tile servers 2. https://github.com/openstreetmap/openstreetmap-website A project to build OpenStreetMap website and API which used Ruby on Rails 3. http://wiki.openstreetmap.org/ OpenStreetMap Wikipedia
  • 4. .. This slide is for... . Introduction . 2/46 1. Who has map data and wants to provide tile servers 2. Who wants to edit map by using editors such as iD, Potlatch 3. Who is interested in building a local OpenStreetMap
  • 6. .. What will we do . Introduction . 4/46
  • 7. .. Contents . Introduction . 5/46 1. Build a tile server 2. Build a website containing map editors, API, and UI 3. Connect two services together
  • 8. .. Environment . Introduction . 6/46 . VirtualBox VM . Ubuntu 12.04 (32-bit) . Memory: 2GB . Storage: 120GB, . Networks: NAT and Host-only Adapter
  • 9. .. My settings . Introduction . 7/46 . User: map . Password: 000000 . ssh installed (sudo apt-get install openssh-server) . Basically, you should know how to get the “ip” of your VM (ifconfig, and it looks like “192.168.x.x”) and how to use “ssh” (ssh map@192.168.x.x) . If you get confused, you probably have to google “virtualbox ubuntu install, virtualbox ssh” . If not, good! Let’s move on!
