4. FREE the DATA !!! Free DATA Open Data Free our data Open content Open access Free data Let data free

5. OpenStreetMap free wiki map of the world OpenStreetMap creates and provides free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways.

15. Tile 256 x 256 pixel, jpeg / png

16. Tile structure http://a.tile.openstreetmap.org/ /${z}/${x}/${y}.png z – zoom 0 – 18 X goes from 0 (left edge is 180 °W) to 2^zoom − 1 (right edge is 180 °E) Y goes from 0 (top edge is 85.0511 °N) to 2^zoom − 1 (bottom edge is 85.0511 °S) http://wiki.osm.org/wiki/Slippy_map_tilenames

17. Openlayers Online site www.OpenLayers.org … init() …

18. OpenLayers JS var map, layer; function init(){ map = new OpenLayers.Map( 'map'); layer = new OpenLayers.Layer.OSM( "Simple OSM Map"); map.addLayer(layer); map.setCenter( new OpenLayers.LonLat(-71.147, 42.472).transform( new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject() ), 12 ); }

19. Leaflet http://cdn.leafletjs.com/leaflet- 0.4.5/leaflet.js html, body, #map { height: 100%; }

20. Leaflet var map = L.map('map').setView([51.505, - 0.09], 13); L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', { attribution: '© OpenStreetMap contributors' }).addTo(map); L.marker([51.5, - 0.09]).addTo(map).bindPopup('A pretty CSS3 popup. Easily customizable.').openPopup();

21. basic map normal html website some js calls to: openlayers CSS needed to set up arrows, plus/minus, … needed with and height of the map div probably override body, html height to 100% calling new map _after_ div exists

22. Online map for mobiles no hover/onmouseover event ;( mobile browser stealing double click click vs. click-and-move many tiles / pictures loading high browser cpu/ram load newer versions are aware of this

23. mbtiles tiles – many many small images in filesystem z/x/y.png bevare of strange little things called inode (df -i) mbtiles – sqlite database of tiles quite slow for serving but fast for transfer many frameworks to mimic tiles '/tms/mbtiles.php?db=cyklo&z={z}&x={x}&y={y}'

24. mbtiles for mobile several applications for mbtiles -> tiles run on mobile iOS SDK by mapbox … tiles are huge: Bratislava 200-400 MB

25. TMI ??

26. Create your own tiles download OSM data from planet.osm.org or download.geofabrik.de or … using Osmosis: get a smaller portion feed into a program, get tiles Mapnik, Maperitive, Osmarender, Tilemill, … put tiles on a webserver, on another device create fancy good looking website

27. Mapnik Standard for high load server possibilities: minutely update from main OSM db mod_tile for ondemand rendering (apache module) very fast, postgis based minus pain to setup

28. Osmarender older package (pre mapnik) rendered on home desktops, tiles only stored on server huge disk requirements not developed any more (freemap.sk is somarender based, forked many years ago)

29. Maperitive free as beer MS Windows only application easy to setup and run (if you have MS Windows) produces tiles/mbtiles

30. Tilemill Ubuntu (and MS Windows & Mac) FOSS no Debian package (please, please, fix) desktop (and server) application Reads postgis, shp, Output tiles, mbtiles, Mapnik configuration, pdf easy to setup and run

31. Vectors for mobiles no standard comparable to tiles several possibilities huge performance problems with wrong programs

32. Maemo OSM2Go – editor Gosmore Marble http://wiki.osm.org/wiki/Software/Maemo

33. GpsMid J2ME application one midlet with data display, routing

34. Sygic Sygic has OSM based product please write them to make it public propretriary, but Slovak

35. Routing, navigation

36. Navit android + openmoko GPL v2 (also apple + …) full application offline rendering offline routing

37. Gosmore BSD for android, linux, … offline viewer and routing bzcat...osm.bz2 |./gosmore rebuild

38. Not only cars are transportworthy

39. OsmAnd GPL v3 Android full app offline display, offline navigation OsmAndMapCreator for your data

40. Other osmdroid – offline viewer (not Osmdroid) Rmaps … http://wiki.openstreetmap.org/wiki/Android

41. Mapsforge LGPL v3. library for android drop in replacement for google maps api change from com.google.android.maps to org.mapsforge.android.maps. No "<uses-library..." reference no API key → extra setMapFile(File) method (no offline routing yet) Osmosis plugin to create binary data

42. Freemap plugin Freemap.sk Locus plugin 110 MB hiking of Slovakia ready on android playground (uses mapsforge)

43. iPhone http://wiki.openstreetmap.org/wiki/Apple_iOS ? anybody ?

44. Last but not least: EDIT !!! OpenStreetMap: free wiki map of the world

45. How to edit http://wiki.osm.org/wiki/Beginners'_guide Collect data Upload data Create/Edit OSM data Label Data and add details Render and use maps

46. Programs Potlatch (WTFPL licenced) Josm, Merkaator OSM2go Mapzen POI collector, Osmaptuner, OsmAnd, Online tools … API (and libraries to use it)
