You dont need geoserver or mapserver to serve the tiles. Put them on a webserver and access them with OpenLayers.Layer.GeoWebCache

You can download the updated gdal2tiles.py for Google/OSM tiles by link http://gisfile.com/user/admin/gdal2tiles.py

The plugin layer has no functionality to export to an image file. Instead, you can save map canvas image (File - Save as Image. A world file is outputted together), and then convert the image to GeoTIFF with the Translate (Convert format) tool of GDALTools. In the tool dialog, the target SRS field should be filled with the CRS of your map (EPSG:27039).

Yes, it is definitely possible. QGis has a QTiles plugin, which uses gdal2tiles under the hood, AFAIK. Then you can use leaflet/openlayers to read your tiles from the created directory structure.

OpenCycle (OSM Based) Landscape Terrain (ThunderForest) created and all credit goes to Andy Allan http://www.gravitystorm.co.uk/projects/ "The Thunderforest Platform is the 4th major revision of the systems that powers OpenCycleMap."

You can use the gdalwarp utility (http://www.gdal.org/gdalwarp.html) to subset an image, the command would be something like: gdalwarp -te tilexmin tileymin tilexmax tileymax \ -t_srs targetproj.wkt \ -of GTiff \ bigmosaic.tiff smalltile.tif Where 'targetproj.wkt' is a well known text file file containing the output projection (this can be the same as ...

I've managed to solve this in a different way. I used this post http://www.aubrett.com/InformationTechnology/Geospatial/gdal2tilesTMSStructure.aspx to create TMS tiles and than using ol.source.XYZ to display them.

OK, so I figured out what is wrong! I needed to change the position of the transparent statement like this: Notice that transparent statement has gone in the above bracket. Thanks everybody for participating!

Check your Geoserver Layer Setup. Open the WMS layer and go to the Publishing Tab .. There is a check box under WMS Settings labeled Opaque, make sure that this is unchecked.

Check your coordinates in these layers. Maybe they don't match on each other and you are switching from one system to another with layer switching... I am not sure what are your WMS made of. Is that blue line a vector? If it is raster it can cover all other layers (it has no transparency) with white border we see around line (maybe it has defined boundaries ...

create your overlay offline(but dynamically) using the programming language of your choosing. it'll be a bit complex but the basic pseudo code would be: browser javascript send request url for overlay acquire gis bounds for tile server side gather all points and sort by their relevance create image(transparent) for each point: (least relevant first) draw ...

Answering my own question, here's the solution I went with: roll-your-own in python. The map in question uses scale-dependent rendering, so, I wanted to do a different render for each 'z' (integer TMS zoom level, 10 thru 17 in this case). Overall workflow, once for each zoom level: 1) render from qgis to tif with a worldfile (i.e. the tif will have ...

I dont think there is an easy and simple method. I also found qtiles did not work. Qgis Server is probably the easiest route, because it all uses the same styling system. However it does involve an awful lot of software. mapserver, tilecache may be easier to install in some situations, i get the impression it has less dependencies. the simplist way might ...
