As you can see, acquiring a topographic map is essential for any permaculture property design work! However, the problem is that getting a topographic map that explicitly shows your property features with a satisfactory contour overlay can get rather expensive pretty soon. For a detailed and accurate topographic map, with contours every 2 ft/0 ...
Topo tip: • Know what map scale you’re using to measure distance. Refer to the scale bar at the bottom of the map. How do I measure distance on a map? Use the scale bar found at the bottom of every NRCan topographic map to determine distances . between points or along lines on the map sheet. Use the secondary division on the left of the scale

Draw or select a line across the topographic map through a region of interest to you (e.g., through a hill) that you will use to draw your topographic profile. In Figure 6.11 the line is labelled A-B. Draw a parallel line the length of this line horizontally near the top of the blank paper. This is the x-axis of your profile.
Feb 14, 2020 · With a protractor, draw a magnetic north line anywhere on your map. The declination diagram in the margin of the map will give you the direction and size of the angle between grid north and magnetic north. Diagram I - Orienting a map using a compass. Do not use the margin diagram itself as the angles are often exaggerated by the cartographer so ...
Aug 31, 2019 · If the topographic map in Figure 3.6 has a fractional scale of 1:12,000 then 1 inch is equal to 12,000 inches or 1000ft; this 1inch = 1000ft equivalency is for the horizontal scale. When we hold a ruler to the y-axis of the topographic profile in Figure 3.6, we see that 0.5 inches = 50ft, which means 1 inch = 100ft on the vertical scale.
