New options. The end result of using 2. You can see the extrude effect on the side of the trees.
Trying to mask the effect. That is fine when you are learning or want to quickly create maps. The advantage of using QGIS software to create new vector layers is that you have a great deal of freedom and control over the types of data you can use and the features and attributes that you can create. This in turn means that you can create custom maps far beyond what can be achieved in Google Earth or Google Maps Engine Lite. You have seen this firsthand with the points, lines, and polygons vector layers you learned how to create in this lesson. If you found data on, for example, public health records in the 18th century, you could create a new layer to work with what you already created showing the distribution of typhoid outbreaks and see if there are correlations with major roads and settlements.

Contents Lesson Goals Getting Started Lesson Goals In this lesson you will learn how to create vector layers based on scanned historical maps.
We are now going to add a second historical map as a raster layer. Click Settings and then Options. Remove the Holland Map right click on it and click Remove and try adding it again. Figure 3 In previous steps you have selected and unselected layers in the Layers window by checking and unchecking the boxes next to them. Figure 4 We will now create a point shapefile, which is a vector layer. Figure 8 Uncheck all layers except settlements.
Reselect i. Select the 3 dot feature button. An Attributes window will appear. Leave id field blank at time of writing, QGIS appears to be making two id fields and this one is unnecessary. In the Year field type in To locate Princetown, look for Richmond Bay and Cape Aylebsury on the north coast to the west of Cavendish , here you will find Princetown shaded-in near the boundary between the yellow and the blue If you look at the Wikipedia entry for the city you will notice that because of a shallow harbor, Princetown did not become a major settlement.
Click OK Figure 13 We will now now create another vector layer — this layer will be a line vector. Select road layer in the layers window, select Toggle Editing on the top toolbar, and then select Add Feature Figure 14 First trace the road from Charlottetown to Princetown. Click on Charlottetown and then click repeatedly at points along the road to Princetown and you will see the line being created. Repeat until you arrive at Princetown, then right-click. Figure 16 We can see that some of these roads correspond closely to modern roads, while others do not at all correspond.
