| 04:02 | On the canvas, India map with some cites and labels is displayed. |
| 04:08 | This map file can be exported to image format for the purpose of printing or publishing . |
| 04:15 | QGIS has a tool called Print Composer. |
| 04:19 | It allows you to create maps in the format that is easy to read. |
| 04:24 | Click on Project menu on the menu bar and select New Print Composer. |
| 04:31 | Composer title dialog-box opens. |
| 04:35 | You will be prompted to enter a title for the composer. |
| 04:40 | Type India-Map as title. |
| 04:44 | Click on OK button. |
| 04:47 | Print composer window opens. |
| 04:50 | Print Composer provides you with a blank canvas. |
| 04:54 | On the right-side beside the canvas, you will find two panels. |
| 04:59 | The upper panel and the lower panel. |
| 05:03 | To enable the panels, click on View menu.
|
| 05:08 | From the menu scroll down and select Panels. |
| 05:13 | The sub-menu shows the list of panels.
Here some panels are already selected. |
| 05:21 | Click on the panel name to select it. |
| 05:24 | The panel appears on the right side of the canvas. |
| 05:28 | All Print Composer tools are available in menus and as icons on the toolbars. |
| 05:37 | The tool bars are present on the left as well as on the top of the Composer window. |
| 05:45 | For more information, please see additional material provided along with this tutorial. |
| 05:52 | Now let us start to assemble our map. |
| 05:56 | In the Print Composer window, click on Zoom full button on the tool bar. |
| 06:03 | This will display the layout to its full extent. |
| 06:07 | Now we have to bring the map view that we see in the QGIS Canvas to the Composer. |
| 06:14 | Click on Add new map tool on the tool bar. |
| 06:19 | Move the cursor on the composer window. |
| 06:23 | The cursor is now seen as plus (+) symbol. |
| 06:27 | This shows that Add Map button is active. |
| 06:31 | Click and drag the left-mouse button to draw a rectangle on the Composer window. |
| 06:37 | Leave margins along the edges. |
| 06:40 | You will see that the rectangle window will be rendered with the map from the main QGIS canvas. |
| 06:48 | The rendered map may not be covering the full window. |
| 06:43 | Click on Move item content tool on the left tool bar. |
| 06:59 | Using left mouse button, move the map in the window and centre it. |
| 07:05 | Leave space along the top for the title. |

| 07:30 | Now all the features in the grid section are enabled. |
| 07:35 | If required, there is an option to change CRS.
I will leave it as such. |
| 07:43 | Select the Interval values as 10 degrees in both X and Y direction using drop-down arrows. |
| 07:51 | Scroll down to the Grid frame section and select a Frame style.
I will select Zebra. |
| 07:59 | There are options to change frame size, thickness, color, etc. |
| 08:07 | Select the options that suits your requirement. |
| 08:12 | Scroll down and check the Draw Coordinates check-box. |
| 08:17 | Adjust the Distance to map frame till the coordinates are legible. |
| 08:23 | Click on the upward or downward arrow to move the labels. |
| 08:30 | Select the Coordinate precision as 1. |
| 08:34 | This will display the coordinates upto the first decimal. |
| 08:38 | Next, we will add a North Arrow to the map. |
| 08:43 | The Print Composer comes with a good collection of map related images. |
