In the New Shapefile Layer window, Check the Point radio button. This opens the New Shapefile Layer window. Procedures for adding points are similar to the polygon and line features already highlighted above. Change the thickness of the line and colour if need be. Digitize the other lines (connecting lines) enter attribute values in the attribute window. Ensure the Enable topological editing and Enable snapping on intersection boxes are checked. Change Layer selection to the active layer (i.e. Click on Settings tab > Snapping Options…. Type in the id number and other fields created earlier, e.g. Once you have finished digitizing the line, Feature Attributes window pops up. After adding the last point, right-click to end tracing the linear feature. Click on Add Feature button to start tracing the line features. Click on Toggle Editing button to activate the digitizing tools. Save the line feature with appropriate name in your working folder. Type in Field name(s) in the ‘Name’ space and click ‘Add to fields list’. In the New Shapefile Layer window, Check the Line radio button. Click on Layer tab > Create Layer > New Shapefile Layer… or press and hold Ctrl+Shift+N keys on the keyboard. Use Add Raster Layer tool to add your satellite image or scanned map. 
Select Simple fill > from Symbol layer type, change Simple fill to Outline: Simple line > Choose a Colour for the outline > Apply > OK.Double click the layer in the layer list.Note:you can make your polygon hollow (removes solid colour and shows only outline). Use the Split Features tool to split the Country into individual State/Province.Use the Add Feature tool to draw the boundary of the Country to make a single polygon.Country with States/Provinces then you can use the Split Features tool to accomplish this task. In a situation where you want to digitize many adjacent polygon features (sharing boundaries) e.g. You have successfully digitized your first polygon feature. Fill in the id number and other fields created earlier, e.g. Once you have finished digitizing the polygon, Feature Attributes window pops up.After adding the last point, right-click to end tracing the polygon.Click on Add Feature button to add the first polygon.Note: If you cannot find Toggle Editing button, ensure that the Digitizing toolbar is checked ( View > Toolbars > Digitizing Toolbar)
Select the vector layer in the layer list. The shapefile should appear in layer panel. In order to start digitizing, you will need to be in edit mode. To do this, select the field you wish to remove, then click ‘Remove field’ button. Note: You can remove any field already added to the ‘Fields list”. 
Save the polygon feature with appropriate name in your working folder. Type in Field name(s) in the ‘Name’ space and choose the type of attribute. In the New Shapefile Layer window, check the Polygon radio button. Click on Layer tab > Create Layer > New Shapefile Layer… or press and hold Ctrl+Shift+N keys on the keyboard. CREATE AN INTERSECTION LAYER IN TRANSCAD HOW TO
To learn how to load raster data, check my previous post ‘Getting Started with QGIS’ By the end of this tutorial, you would have acquired the following GIS basic skills: This tutorial will take you through the procedures for digitizing scanned map or any other raster dataset in QGIS. Digitizing is an essential process of any GIS related project, it is generally part of the data conversion process.
