How do I use the osm tile map server in mapinfo 10.5? What do the .tab and .xml files have to contain? What does the projection data look like? asked 02 Dec '10, 15:04  jp_osm edited 20 Jan '11, 14:11  TomH ♦♦ |

OpenStreetMap tiles are in Spherical Mercator EPSG:900913 (EPSG:3857). The origin is top left. The URL layout is http://tile.openstreetmap.org/%Z/%X/%Y.png I've never used MapInfo, but a likely good starting point is to modify an existing .tab/.xml setup designed for Google Maps or similar map service. The OpenStreetMap Tile server has a usage policy: https://wiki.openstreetmap.org/wiki/Tile_Usage_Policy This answer is marked "community wiki". answered 02 Dec '10, 17:41  Firefishy ♦♦ edited 02 Dec '10, 17:43 |
Thnx The documentation of MapInfo is not very elaborate on it : V 10.5 has Bing incorporated, and further the documentation just says OSM is fully supported. So from the Bing files and the info of Firefishy I produced : TAB file: !table !version 1050 !charset WindowsLatin1 Definition Table File "open_street.xml" Type "TILESERVER" CoordSys Earth Projection 10, 157, 7, 0 Bounds (-20037508.343,-20037508.343) (20037508.343,20037508.343) and XML file : [?xml version="1.0" encoding="utf-8"?] [TileServerInfo Type="LevelRowColumn"] [Url]http://tile.openstreetmap.org/{LEVEL}/{ROW}/{COL}.png[/Url] [MaxLevel]18[/MaxLevel] [TileSize Height="256" /] [AttributionText Font="Font("Arial",3,12,0,16777215)"]OpenStreetMap[/AttributionText] [/TileServerInfo] This works fairly well, but it has the same problem as I had with Bing (which promted my efforts in the first place) : the produced maps are not very sharp, they appear somewhat fuzzy at any zoom level. Probably has to do with resolution of mapwindows in MapInfo, compared to the downloaded tiles : I suppose I have to somehow adjust the MapWindow to multiples of 256 pixels or so ... Not sure on how to go about that : Any ideas are welcom By the way, I am a very light user. jp_osm answered 03 Dec '10, 09:28 jp_osm |
