| 36 | | * Load / Download openstreetmap data and go to your favourite area |
| 37 | | * Show the 'Layers' panel if it isn't showing already (Click the toggle button: [[Image(source:trunk/images/dialogs/layerlist.png)]]) |
| 38 | | * Click the menu option "WMS → Landsat" (or whatever named WMS server you want to use) This should cause it to create a new imagery layer. |
| 39 | | * Wait a few moments for it to begin fetching image tiles. |

| 41 | | As you pan around it will download more tiles. It also seems to remove tiles which are out of viewing area, to free up memory. |
| 42 | | |
| 43 | | To remove the imagery and stop all WMS downloading, select the layer and click the trash can button. You can also temporarily toggle visibility of the layer (keeps imagery in memory). Right click on the layer (in the layers panel) to access further WMS layer options. |
| 44 | | |
| 45 | | When your WMS layer is selected, the data layer is shown as deselected (dark grey). Simply select your data layer again (often called 'unnamed') to restore normal colours. It is also possible to display the WMS layer "above" the data layer, which will hide the data layer completely. Use the up/down arrows to fix the ordering. |
| 46 | | |
| 47 | | You can adjust the positioning of the imagery by clicking [[Image(source:trunk/images/mapmode/adjustimg.png)]] button on the left. In this mode you can drag and drop the WMS layer. Press the button again to lock it in place. This can be useful if the imagery appears to be offset from reality, but note that your GPS unit isn't perfect. A bad GPS signal can cause an entire trace to have an offset from reality, so you may find it useful to check also by downloading other GPS traces recorded for the area. |
| 48 | | |
| 49 | | You may need to adjust your map colours ('Edit' menu -> 'Preferences') to be darker or lighter, to contrast with the images you are using. |
