Creating
a mud map (line, point and area map) for students to use when out of the classroom in school grounds or
excursion
Equipment prepared ahead with one set per 3 students:
- A3 satellite image of a section of Mawson Lakes Campus
- Tape measure
- Pencil, coloured pencils and sharpener
- Erasure
- Ruler. Protractor and compass
- Watch/time
- Tracing paper
- Sticky tape
- A3 white paper – same size as aerial photo
- Window as a light table
- Observation skills
Download a satellite image of the field site from Google Maps A3.
· Print one colour copy between 3 students.
Step 2: Observations at the site
- Determine the scale of the photo by measuring a feature on the map
that is a known measurement at the site.
- Identify the main features of the photo that students will focus
on, i.e. buildings and trees as areas, roads as lines and special features as
points (parking machine).
- Orientate North using the sun and a clock, or a compass – place on image.
Step 3: Using tracing paper digitise the photo to create a vector map (point, line and area map). To do this, trace over the photo to create a map with lines, points and areas
Step 4: Tracing outline
- Attach tracing to light table or window & cover with white
sheet of paper.
- Transfer the tracing to the white paper.
- Use a ruler and protractor to ensure lines are straight.
Step 5: Complete mud map:
- Place North on the map.
- Put line and Representative fraction (1: …) scale at the bottom
left hand corner of the map.
- Create a legend and place at the bottom right hand corner of the
map.
- Colour for features according to legend.
- Label key features.
- Place title at top right hand corner of map.
Ensure
the map has BOLTSS plus R:
