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

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.

… not to forget

ODbL Open Database Licence LGPL of databases You are free: To Share: To copy, distribute and use the database. To Create: To produce works from the database. To Adapt: To modify, transform and build upon the database.

Database structure

Tile 256 x 256 pixel, jpeg / png

Tile structure /${z}/${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 °N) to 2^zoom − 1 (bottom edge is °S)

Openlayers Online site … init() …

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( , ).transform( new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject() ), 12 ); }

Leaflet /leaflet.js html, body, #map { height: 100%; }

Leaflet var map = L.map('map').setView([51.505, ], 13); L.tileLayer(' { attribution: '© OpenStreetMap contributors' }).addTo(map); L.marker([51.5, ]).addTo(map).bindPopup('A pretty CSS3 popup. Easily customizable.').openPopup();

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

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

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}'

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

TMI ??

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

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

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)

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

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

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

Maemo OSM2Go – editor Gosmore Marble

GpsMid J2ME application one midlet with data display, routing

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

Routing, navigation

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

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

Not only cars are transportworthy

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

Other osmdroid – offline viewer (not Osmdroid) Rmaps …

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

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

iPhone ? anybody ?

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