Sooner or later every designer comes across the exciting job of producing a map, whether it’s on aleaflet or website the overall aim is to visually document a particular area of land to allow for people tofind their way to a place of business or event.An important factor is the amount of detail required for the map, for most situations the map should bebasic enough to provide a recognisable road structure without too much intricate detailing. As you willhave seen on existing maps, the use of graphics and colours are important to distinguish betweendifferent types of road, this tutorial will cover the process of using Illustrator brushes to create a map of asmall road network.

The finished map graphic needs to be crisp and clear which is why the map will be created in vectorformat in Illustrator. Imagine if the map needs to be enlarged on the leaflet as a client requirement, inPhotoshop you would be left with fuzzy pixelated edges. Plus, the complete map will be editableallowing the road shapes to be tweaked without having to delete and redraw the complete line.

Start by drawing a straight line (hold Shift) on your new documents, add a quite thick blue stroke. Thiswill be the base for our UK Motorway, being the largest type of road this line needs to be the thickest.



Copy and paste the line back into place (CTRL / CMD + F), and change the weight to a thinner strokeand colour in white. This will give a blue and white striped appearance to simulate the dualcarriageways.

Select both of your strokes and click the 'New Brush' icon in the brushes window.



In the option box select the 'New Art Brush' radio button.

In the next dialog box you have the option of naming your new brush, in this case it's a 'Motorway'.Also check the direction is running along the length of the brush and not across it.

You will now notice your new brush appears in your Brushes Palette. (I have deleted the defaultbrushes here to allow for easier access)



Go ahead and repeat the previous steps to create a selection of brushes to represent the different roadtypes. Experiment with different stroke weights and arrangements to produce some interesting effects.Remember to produce these brushes according to the hierarchy of the roads they represent, for examplea minor road needs to be thinner and less prominent than a major road.TIP: Extend the inner stroke outwards slightly on roads that will need to interconnect, this will allowthem to merge together without the outline running across the joint.

As well as the road graphics, use circles to produce matching junction icons. Using similar fill andstroke colours will allow them to blend with the roads.



Now we're ready to draw the actual map, create a container box for reference and press CTRL / CMD +2 to lock it. Don't worry about any roads extending beyond this container, we'll clip these later.Use the Pen tool to draw your first major road, refer to an existing map to ensure the shape and scale iscorrect. This is where all you USA residents have it easy! The UK is full of curly whirly roads which aregreat for driving on, but a pain to draw up!!



Add the appropriate brush to the new path, transforming it into a Motorway.

Add in a couple of junctions where necessary and use the text tool to provide additional information.



To add an interconnecting road draw the path as required, then use CTRL / CMD + [ to send the newpath to the back of the stack allowing for the junction circles to remain on top.



Continue drawing paths and selecting the appropriate brush to produce a network of roads.



Go in and add in the junctions and roundabouts by copying and pasting the junction circles createdearlier.

Work down the hierarchy onto the minor roads, which will be even more intricate. Draw each path andadd the Minor Road brush. This is where the tip mentioned above comes in handy, allowing the roads tointerconnect without the outline running across the joints.



To add some names to your roads, use the Pen Tool to draw a path in a similar contour to a particularroad.

Then, select the Type tool and hover over this line until you see the Type of Path icon appear. Type outyour road name and you will notice the text flow follows the line, you can use the little handles to editthe position of the text, or use the Direct Selection Tool to fine tune the shape of the path.



Finally, trim off the excess roads from beyond the container. Copy and Paste the container shape(CTRL / CMD + Alt + 2 to unlock the object), then select all (CTRL / CMD + A). Go to object >Clipping Mask > Create and notice how the lines are trimmed back to the outline of the box.
