Study Notes
Maps, Plans, and Representations
National Road Maps
- Show major routes, roads, and distances between major cities and towns in South Africa
- Skills:
- Decide on the most appropriate route between destinations
- Estimate traveling costs and times
- Plan stopping points for accommodation, breaks, or refueling
- Use distance tables to determine distances
Strip Charts
- Show locations of towns, other roads, and points of interest on a specific route
- Skills:
- Determine more accurate traveling distances on specific sections of a route
- Decide on appropriate stopping points for refueling or breaks
- Estimate traveling costs and times
- Use distance markers and indicators on the chart
Street Maps
- Show positions and names of streets and other locations within a city
- Skills:
- Identify locations using symbols
- Follow and provide directions using street names and directional indicators (e.g., left, right)
- Use a grid reference system with the street index to find specific streets
Housing Complex Maps
- Show positions of houses within a small housing complex
- Skills:
- Work with a map that shows a small area with limited detail
- Follow and describe directions to a specific location within the complex
Using Scales
- Use the given scale to estimate traveling distances when a distance table or distance markers are not provided
- Two types of scale calculations:
- Type 1: Map Measurement to Actual Distance
- Measure a distance on a map
- Use the given scale to convert this measurement to the actual distance
- Formula: Actual Distance = Map Measurement × Scale Factor
- Type 2: Actual Distance to Map Measurement
- Start with a known actual distance
- Use the given scale to convert this actual distance to the map measurement
- Formula: Map Measurement = Actual Distance ÷ Scale Factor
- Type 1: Map Measurement to Actual Distance
Types of Scales
Number Scale
- Expressed in the format 1:50,000
- Conversion is straightforward: enlarge or reduce by the scale factor
- A number scale shows a specific relationship between the size of the area on the map and the actual size of that area
Bar Scale
- Shows the relationship between measured length and actual distance
- Measuring with a ruler on the bar scale shows how many measured units are equal to actual distance
- Different from a number scale in that it does not state how many times smaller the map is from the actual size, but rather how many measured units are equal to a specific number of actual units
Building Plans
Key Concepts
- Floor Plan:
- Function: Shows a 2-dimensional perspective of a building or structure as seen from above, without the roof
- Purpose: To see the design and dimensions of the inside of a building or structure
- Visible Features: Dimensions and layout of the inside of the building, including lengths and widths of the building, windows, and doors
- Elevation Plan:
- Function: Shows a 2-dimensional perspective of a building or structure as seen from the side
- Purpose: To see the design and dimensions of the outside of a building or structure
- Visible Features: Dimensions and layout of the outside of the building, including the design of the roof, walls, windows, and doors
- Design Drawing:
- Function: Shows the design, layout, and components of an item to be constructed or manufactured
- Purpose: To see what a completed item will look like and the dimensions of its parts
- Visible Features: The design plan shows the different component parts, dimensions of these parts, and specific instructions on how they should look
Key Concepts for Working with Plans
- Describe features of a building/structure
- Match features between plans
- Understand compass directions
- Use scale to determine dimensions
Design Drawings
- Describe the item/object shown on the design plan
- Identify the dimensions of the item/object
- Describe the different component parts required to make the item/object
- Identify a cutting list of parts needed to make the item/object
Key Concepts for Design Drawings
- Describe the item/object
- Identify dimensions
- Describe component parts
- Cutting list
Drawing Scaled Plans
- Calculate plan measure from actual dimension
- Formula: Plan Measure = Actual Dimension ÷ Scale Factor
- Use the given scale to reduce the actual measurement proportionately

- A number scale shows a specific relationship between the size of the area on the map and the actual size of that area
Bar Scale
- Shows the relationship between measured length and actual distance
- Measuring with a ruler on the bar scale shows how many measured units are equal to actual distance
- Different from a number scale in that it does not state how many times smaller the map is from the actual size, but rather how many measured units are equal to a specific number of actual units
