Newbie question: I designed a map (not Earth-related) in Photoshop and I want to use something like Mapbox to serve the map and make it dynamic (bounding boxes, zoom in/out, etc). How can I go from an SVG/PNG to a tile-based map?

TileMill accepts as data input geoJSON, SQLite, PostGIS. For example:

{"type":"FeatureCollection","features":[
{"type":"Feature","id":"BRA","properties":{"name":"Brazil"},"geometry":{"type":"Polygon","coordinates":[[[-57.625133,-30.216295],[-56.2909,-28.852761],[-55.162286,-27.881915],[-54.490725,-27.474757],[-53.648735,-26.923473],[-53.628349,-26.124865],[-54.13005,-25.547639],[-54.625291,-25.739255],[-54.428946,-25.162185],[-54.293476,-24.5708],[-54.29296,-24.021014],[-54.652834,-23.839578],[-55.027902,-24.001274],[-55.400747,-23.956935],[-55.517639,-23.571998],[-55.610683,-22.655619],[-55.797958,-22.35693],[-56.473317,-22.0863],[-56.88151,-22.282154],[-57.937156,-22.090176],[-57.870674,-20.732688],[-58.166392,-20.176701],[-57.853802,-19.969995],[-57.949997,-19.400004],[-57.676009,-18.96184],[-57.498371,-18.174188],[-57.734558,-17.552468],[-58.280804,-17.27171],[-58.388058,-16.877109],[-58.24122,-16.299573],[-60.15839,-16.258284],[-60.542966,-15.09391],[-60.251149,-15.077219],[-60.264326,-14.645979],[-60.459198,-14.354007],[-60.503304,-13.775955],[-61.084121,-13.479384],[-61.713204,-13.489202],[-62.127081,-13.198781],[-62.80306,-13.000653],[-63.196499,-12.627033],[-64.316353,-12.461978],[-65.402281,-11.56627],[-65.321899,-10.895872],[-65.444837,-10.511451],[-65.338435,-9.761988],[-66.646908,-9.931331],[-67.173801,-10.306812],[-68.048192,-10.712059],[-68.271254,-11.014521],[-68.786158,-11.03638],[-69.529678,-10.951734],[-70.093752,-11.123972],[-70.548686,-11.009147],[-70.481894,-9.490118],[-71.302412,-10.079436],[-72.184891,-10.053598],[-72.563033,-9.520194],[-73.226713,-9.462213],[-73.015383,-9.032833],[-73.571059,-8.424447],[-73.987235,-7.52383],[-73.723401,-7.340999],[-73.724487,-6.918595],[-73.120027,-6.629931],[-73.219711,-6.089189],[-72.964507,-5.741251],[-72.891928,-5.274561],[-71.748406,-4.593983],[-70.928843,-4.401591],[-70.794769,-4.251265],[-69.893635,-4.298187],[-69.444102,-1.556287],[-69.420486,-1.122619],[-69.577065,-0.549992],[-70.020656,-0.185156],[-70.015566,0.541414],[-69.452396,0.706159],[-69.252434,0.602651],[-69.218638,0.985677],[-69.804597,1.089081],[-69.816973,1.714805],[-67.868565,1.692455],[-67.53781,2.037163],[-67.259998,1.719999],[-67.065048,1.130112],[-66.876326,1.253361],[-66.325765,0.724452],[-65.548267,0.789254],[-65.354713,1.095282],[-64.611012,1.328731],[-64.199306,1.492855],[-64.083085,1.916369],[-63.368788,2.2009],[-63.422867,2.411068],[-64.269999,2.497006],[-64.408828,3.126786],[-64.368494,3.79721],[-64.816064,4.056445],[-64.628659,4.148481],[-63.888343,4.02053],[-63.093198,3.770571],[-62.804533,4.006965],[-62.08543,4.162124],[-60.966893,4.536468],[-60.601179,4.918098],[-60.733574,5.200277],[-60.213683,5.244486],[-59.980959,5.014061],[-60.111002,4.574967],[-59.767406,4.423503],[-59.53804,3.958803],[-59.815413,3.606499],[-59.974525,2.755233],[-59.718546,2.24963],[-59.646044,1.786894],[-59.030862,1.317698],[-58.540013,1.268088],[-58.429477,1.463942],[-58.11345,1.507195],[-57.660971,1.682585],[-57.335823,1.948538],[-56.782704,1.863711],[-56.539386,1.899523],[-55.995698,1.817667],[-55.9056,2.021996],[-56.073342,2.220795],[-55.973322,2.510364],[-55.569755,2.421506],[-55.097587,2.523748],[-54.524754,2.311849],[-54.088063,2.105557],[-53.778521,2.376703],[-53.554839,2.334897],[-53.418465,2.053389],[-52.939657,2.124858],[-52.556425,2.504705],[-52.249338,3.241094],[-51.657797,4.156232],[-51.317146,4.203491],[-51.069771,3.650398],[-50.508875,1.901564],[-49.974076,1.736483],[-49.947101,1.04619],[-50.699251,0.222984],[-50.388211,-0.078445],[-48.620567,-0.235489],[-48.584497,-1.237805],[-47.824956,-0.581618],[-46.566584,-0.941028],[-44.905703,-1.55174],[-44.417619,-2.13775],[-44.581589,-2.691308],[-43.418791,-2.38311],[-41.472657,-2.912018],[-39.978665,-2.873054],[-38.500383,-3.700652],[-37.223252,-4.820946],[-36.452937,-5.109404],[-35.597796,-5.149504],[-35.235389,-5.464937],[-34.89603,-6.738193],[-34.729993,-7.343221],[-35.128212,-8.996401],[-35.636967,-9.649282],[-37.046519,-11.040721],[-37.683612,-12.171195],[-38.423877,-13.038119],[-38.673887,-13.057652],[-38.953276,-13.79337],[-38.882298,-15.667054],[-39.161092,-17.208407],[-39.267339,-17.867746],[-39.583521,-18.262296],[-39.760823,-19.599113],[-40.774741,-20.904512],[-40.944756,-21.937317],[-41.754164,-22.370676],[-41.988284,-22.97007],[-43.074704,-22.967693],[-44.647812,-23.351959],[-45.352136,-23.796842],[-46.472093,-24.088969],[-47.648972,-24.885199],[-48.495458,-25.877025],[-48.641005,-26.623698],[-48.474736,-27.175912],[-48.66152,-28.186135],[-48.888457,-28.674115],[-49.587329,-29.224469],[-50.696874,-30.984465],[-51.576226,-31.777698],[-52.256081,-32.24537],[-52.7121,-33.196578],[-53.373662,-33.768378],[-53.650544,-33.202004],[-53.209589,-32.727666],[-53.787952,-32.047243],[-54.572452,-31.494511],[-55.60151,-30.853879],[-55.973245,-30.883076],[-56.976026,-30.109686],[-57.625133,-30.216295]]]}}

However, I don’t have those coordinates to define the polygon area. Any ideas? Thanks!

That isn't quite how Tilemill is intended to be used. You would need to convert your svg to geojson and add attributes, then redo all your styling.

EDIT: You can use rasters in Tilemill if you save to tif. Projection might be tricky but for a fictitious place it might work ok.

Since you already have an image, something like MapTiler to just cut your image into tiles and generate tiles for all scales you want is probably a better choice. If you still want it served by mapbox you'll need to then convert that tile set into the mbtiles format.

  • Thanks! I’ll give that a go. Maybe I will go with MapTiler, as it might be the best solution. – Alex Mar 17 '14 at 18:05
  • Maptiler will work directly with Openlayers/Leaflet too. Also if you do the tilemill way, just stretch your image to spherical mercator pixel extent and projection won't be an issue. – wildintellect Mar 17 '14 at 19:12

Using PNG you can also use leaflet, just follow the workflow in this blog post: http://blog.thematicmapping.org/2013/06/showing-zoomify-images-with-leaflet.html

Hosting something like this on mapbox seems a bit pointless if you don't real world data or really big imagery, you can just host it on any webserver, its just basic html/javascript.
