Hi, Has anyone successfully used MBTiles to server basemaps in Openlayers? Do any live example exist if yes? yours, Rob _______________________________________________ Users mailing list [hidden email] http://lists.osgeo.org/mailman/listinfo/openlayers-users

Hi Robert,
You can do this through the OpenLayers.Layer.XYZ() class with some code server side to mimic a standard XYZ grid. I've done this within the mapshup framework (http://mapshup.info). Server side, you need to create a script that converts XYZ requests to mbtiles requests. See http://code.google.com/p/mapshup/source/browse/server/utilities/mbtsrv.php for an example of this script. Suppose that you access this script on http://localhost/mbtsrv.php, you should set your layer like this client side : var newLayer = new OpenLayers.Layer.XYZ("mbtile", 'http://localhost/mptsrv.php', {isBaseLayer:true}); Regards Jerome -- http://mapshup.info 2012/1/25 Robert Buckley <[hidden email]>: > Hi, > > Has anyone successfully used MBTiles to server basemaps in Openlayers? > Do any live example exist if yes? > > yours, > > Rob > > _______________________________________________ > Users mailing list > [hidden email] > http://lists.osgeo.org/mailman/listinfo/openlayers-users > Users mailing list [hidden email] http://lists.osgeo.org/mailman/listinfo/openlayers-users |

Thanks for the reply, So TileStache can serve and render the MBTiles to use with openlayers? Would you know if there are possibilities for exporting mapcontent from the openlayers mappanel? This is one of the reasons i´m looking in this directory as I can´t do pdf exports with geowebcache served from geoserver.

I suspect you might have the same problem. We have solved this by
calling the appropriate WMS layer from the geoserver to do the print request. The problem with any tiled base approach is that either you have to cut down the tile parts that run outside of your export area, or you have to go to the closest tile, which at lower resolutions is quite a big geographical distance.

But according to the docs, it will not save tiles to a MBTiles file -- you need an existing MBTiles file, or can use tilestache-seed to create one. > Would you know if there are possibilities for exporting > mapcontent from the openlayers mappanel? > This is one of the reasons i´m looking in this directory as > I can´t do pdf exports with geowebcache served from geoserver. This seems independent of your MBTiles question. TileStache and other map servers probably won't get involved with loading the content of your map and then creating a PDF. Check out some of the resources here: http://trac.osgeo.org/openlayers/wiki/Printing Our current favorite method is wkhtmltopdf. You basically write a new page using JavaScript and OpenLayers as usual, have it set the map's zoom and center and basemap -- so that when the page opens it's showing exactly the map you want. Dump the HTML to a file, have wkhtmltopdf convert the HTML file to a PDF (yes, wkhtmltopdf speaks JavaScript, even jQuery, Bing Maps, and OpenLayers). Really slick. -- Greg Allensworth, Web GIS Developer BS A+ Network+ Security+ Linux+ Server+ GreenInfo Network - Information and Mapping in the Public Interest 564 Market Street, Suite 510 San Francisco CA 94104 PH: 415-979-0343 x302 FX: 415-979-0371 email: [hidden email] Web: www.GreenInfo.org www.MapsPortal.org Subscribe to MapLines, our e-newsletter, at www.GreenInfo.org _______________________________________________ Users mailing list [hidden email] http://lists.osgeo.org/mailman/listinfo/openlayers-users |

Thanks Tobias. I remember your forum post from November last year... "...So to get this working, you might be able add quite a simple loop. In your printprovider.js in line 367 there is a loop to populate thejson object with the layers that you are wanting to get printed. So onto line 369 add: if (layer.url == "http://maps.zgb.de/geoserver/gwc/service/wms"){ layer.url = "http://maps.zgb.de/geoserver/zgb/wms") else {} (untested code, probably missing ;'s and other stuff!)... Toby. ..." This never did work for me....and I decided to enjoy christmas and start the whole thing again in 2012. Unfortunately we are already in 2012 and the niggly little jobs which I need to solve have appeared again! If you have time to help me crack this one I´d be much appreciated. ps..i´m located in D-31822. yours, Rob Von: Tobias Reinicke <[hidden email]> An: Robert Buckley <[hidden email]> Cc: Greg Allensworth <[hidden email]>; "[hidden email]" <[hidden email]> Gesendet: 18:04 Mittwoch, 25.Januar 2012 Betreff: Re: [OpenLayers-Users] Use of MBTIles with openlayers I suspect you might have the same problem.

Wow, what a cool tool! Am I correct in my (brief) reading of the license that it is more permissive than GPL?
I have a client that needs a map to integrate with some of our tools, although I'm guessing that I'd be able to do this without actually modifying the mashup code, simply configuring the widgets and search, etc.
The license mentions "External Modules". Is their documentation or a mailing list for developing those? Thanks, and thanks again for a great tool, is it on the OpenLayers example page somewhere? (http://openlayers.org/dev/examples/) It's a great site for showcasing OpenLayers' capabilities.

Hi Tac !
2012/1/25 Tac Tacelosky <[hidden email]>: > Wow, what a cool tool! Am I correct in my (brief) reading of the license > that it is more permissive than GPL? > > http://www.cecill.info/licences/Licence_CeCILL-B_V1-en.html I really appreciate that you like this application :) Yes the license is more permissive than GPL. It can be compared to the BSD license : you can do what you want with the code without giving back the modifications to the community. The main difference with BSD is that you need to expressively mention mapshup in your software - let the mapshup logo within the map for example. > I have a client that needs a map to integrate with some of our tools, > although I'm guessing that I'd be able to do this without actually modifying > the mashup code, simply configuring the widgets and search, etc. > The license mentions "External Modules". Is their documentation or a > mailing list for developing those? It's a very generic licence so "External Modules" do not refer specifically to mapshup. However the application architecture is based on a "plugin" approach to allow people to develop their own functionality. Unfortunately i had no time yet to write documentation so for the moment you need to look at the code to understand how it works. To have some idea about what you can by configuration, you should look at the default configuration file (http://code.google.com/p/mapshup/source/browse/client/js/mapshup/config/default.js). I'm preparing some minimal documentation to explain how the tool works and how you can configure/modify it to suits your needs. For example, there are some hidden functionalities that are not visible at first sight : - you should try to drag&drop an url on the map (WMS, WFS, GeoRSS) or a file (GeoJSON, JPEG with GPS information stored in EXIF, etc.) - when you click for more than 200ms on the map, a popup menu appears > Thanks, and thanks again for a great tool, is it on the OpenLayers example > page somewhere? (http://openlayers.org/dev/examples/) It's a great site for > showcasing OpenLayers' capabilities. I think that the examples page is dedicated to OpenLayers examples only and not to "OpenLayers based application". But i'll be pleased to showcase OpenLayers capabilities through mapshup !
