MbTiles and Openlayers.Layer.TMS not working about mbtiles-spec HOT 11 CLOSED

Is MbTiles supported in Openlayers? It seems that there is configuration to get tiles.

Please check this example,

http://trac.geoext.org/browser/sandbox/gxm/geoext/gxm/external/OpenLayers.r11966/examples/tms.html?rev=2677

from mbtiles-spec.

The second argument to the constructor should be the base path, not a path of a tile:

new OpenLayers.Layer.TMS("MapBox Tile Natural Earth 2", "http://localhost:8888/", {
    layername: 'natural-earth-2',
    type: 'png',
    transitionEffect: 'resize'
}),

from mbtiles-spec.

Also, OpenLayers does not access MBTiles directly - a component is needed to serve tiles from localhost or any other server. Unless http://localhost:8888/1.0.0/natural-earth-2/0.0.0.png resolves in your iPad app, this won't work.

from mbtiles-spec.

I realise it now that TMS or Openlayers Base Maps (e.g. WMS, TMS, etc.) are design to work on server side.

Since natural-earth-2.mbtiles is sqlite3 base format can I assign it into a sqlite3 database and query it using SQL select statement to get the tiles? If I can do a SELECT query, what is the SQL query and how would it be pass to Openlayers.Layer.TMS?

is "http://localhost:8888/1.0.0/natural-earth-2/0.0.0.png" string that can be equated in text.value? I am not sure where this question is leading to? But fishing for ideas how to pass the data from WebView to the mbtile and vice versa.

Any ideas how to get a local support for MbTiles in mobile gadget without the server?

One possible way is to have a server in the ipad. Possible in Jailbreak ipad and use Tileserver with Node.js.

Still waiting for ipad 2 jailbreak.

You've seen the MapBox iPad App right? This is exactly what it sets out to do.

from mbtiles-spec.

new OpenLayers.Layer.TMS("MapBox Tile Natural Earth 2", "http://localhost:8888/", {
layername: 'natural-earth-2',
type: 'png',
transitionEffect: 'resize'
}),

Can I map this "http://localhost:8888/" into the mbtiles in Objective-C

var sampleDatabase = new DataAccessObject("natural-earth2.mbtiles")

Now in WebView javascript side

http://localhost:8888/ = sampleDatabase

Er, yes, kind of. See the route-me project that has a connector for mbtiles, and the mbtiles ios example. If you aren't going the MapBox for iPad app route or an online server, this is probably a several-week task to do this with OpenLayers, which, unless you really need its other capabilities, isn't a necessary tool for this.

I want Spatialite visualation in Openlayers thru JSTS. I can query my spatialite to render polygons, route, KML just PostGIS terminal is doing. However, I like to do with Javascript Topology Suite (JSTS), PostGIS terminal is using AsWKT function.

I can visualite crime statistic, umemployment figures, property values on Spatialite terminal and get the map in Openlayer canvas.

I am not a programmer / developer, I am struggling with Objective-C
and route-me people are not so helpful at. Does not reply to questions
Hence, I just try to do it javascript / jquery.

OpenLayers unfortunately isn't going to make your job any easier on the iPad. You might want to try out the mbtiles ios example and see if you can modify it to your needs, or see if you can pre-render visualizations and use them in the MapBox iPad app.

Closing; this is outside the scope of this respository.
