The following steps should be taken to correctly sketch an aerial photograph.
1
Draw a four-sided border or frame for your sketch. This must be the same shape as the aerial photograph you are sketching. Unless instructed otherwise, make the frame half the scale of the original (half the length and half the width).
2
Divide the photograph you are sketching into sections. Do likewise with your frame (figure 4). These sections will help you better locate and sketch features of the aerial photograph correctly.
3
Always draw important features such as coastline, skyline and horizon on your sketch map. This will also help you to better sketch features on the map in their correct location.

Title your sketch map, e.g. ‘Sketch of [Name of location] Aerial Photograph’.
Label all features you are asked to sketch in the question.

Tips!

Always use a pencil. Only insert features asked for as well as important features.
If asked to draw houses, buildings or industrial estates, draw the outline shape of them.

Allow plenty of room to properly label your features. Draw double lines for roads and rivers. Use colours sparingly.
Never attempt to trace a photograph you are asked to sketch.
