![]() The user can use the Bulk add Tiles menu to quickly add monitors and performance tiles to the instance view (all object rules and monitors are displayed in the Chose tiles to be added to the view list). To open Performance View and Health Explorer, it is necessary to double-click the corresponding tile (performance tile and monitor tile, respectively). Moving aggregated tiles within the expanded group in Datacenter View.If you use the number 2, you will be able to zoom in or out and stay in OSM scales (approximatively).The tiles can be moved by means of drag-n-drop.ĭatacenter dashboards allow the following methods of tile moving: Last hint : in Qgis, you can define the zoom factor to use when zooming in or out with the mouse wheel. ![]() This means the next version of Qgis will give you the ability to define and save OSM scales, which will help a lot. This feature is beeing completed by Alexander Bruy and will be in Qgis master branch soon. This is why I proposed a patch to let the use defined a scales list for each project. It could be great to have the above list of OSM scales instead of the Qgis scales. Since Qgis 1.8, there is a scale combo box in the right bottom of the map, alowing to use predefined scales. Here are the approximated scales you need to use to display your data correctly : Otherwise Qgis will show warped OSM tiles. If you do not want to see OSM data with a blur effect, you must zoom to one of OSM predefined scale. The scales are defined by the provider (Google as its own, OSM too, etc.). So if you want to refresh old OSM tiles, you have to manually remove the content of this folder some time to time. Downloaded tiles are stored here and Gdal uses this folder as a cache (which is good, because you won't ask the same tile twice, which will give OSM server some rest). ![]() Gdal creates a gdalwmscache folder in your home directory.OSM tiles are shiped in Mercator, so I usually ask Qgis to dynamically reproject my data into Mercator whenever I want to use OSM as a base layer.The zoom to your vector extent, and then open the XML file as a raster. If you have problems to zoom to the correct extent, you can set your project spatial system reference to EPSG:900913, activate on-the-fly reprojection, and add a vector file you know well. And this is it ! Gdal gets the tiles for you and Qgis display them smoothly. You can now simply open Qgis, then use the menu Add a raster layer, and choose the XML file you have just saved. Basically, the only thing you have to do is to create a simple XML file with the following content :Īnd save it as openstreetmap_mapnik.xml somewhere in your file system. The Gdal documentation ( ) is very helpful. Every Qgis compiled with Gdal 1.7 or higher can therefore read this format directly. Since Gdal 1.7.0, support for TMS has been added. Qgis uses Gdal as a generic driver to read and write raster. There is a plugin which helps to get tiles from OpenStreetMap, but I do not find it simple enough for me. I was a bit frustrated not to be able to simply load OpenStreetMap tiles in my prefered GIS desktop application, Qgis. This is a common protocol for webmappers. TMS is much more simple as WMS, and is a widly used in web applications via OpenLayers or Leaflet. It is also possible to use this protocol to retrieve Google Maps or Mapquest tiles too. TMS (Tiled Map Service : ) is the protocol used by OpenStreetMap server to provide access to the tiles. How to display OpenStreetMap data tiles with no plugin inside Qgis
