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.
- Step 1. Locate Your Property on The Contour Map Creator Website
- Step 2. Draw A Sampling Area
- Step 3. Get A Contour Map
- Step 4. Import The Contour Map Into Google Earth
Open the http://contourmapcreator.urgr8.ch/ website in your browser. There you’ll find a free web app that lets you generate contours for your property at the click of a button. Now zoom in on your property, use the search bar, and then use your mouse to center the map with your property in the middle. Note:Don’t zoom in too much, as you’re also tr...
Mark a rectangle by adding two pins to the map. Put one pin in the corner and the other in the opposite one.
Now adjust the plot options, check the level interval option, and put in 5m/15ft (or less). This determines the resolution of your contour map; in this case, you’ll get a contour map with contours every 5m/15ft. Click the ‘Get Data’ button under the sampling tab – and the app generates a contour map for you. Now you could leave it at that, take a s...
Scroll down and press ‘Download KML file.’ Now locate that file in your download folder and open it in Google Earth. Launching the application will automatically zoom in onto your property, and you’ll have contour lines overlaid on top of the satellite photo background. Note:If Google Earth doesn’t automatically take you to the area with contours, ...
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 a topographic profile on graph paper to convince them they can do it. You will need to print out Figure 15.5, and if you do not have any on hand, graph paper, found in Worksheets. If you require further guidance, please watch these step-by-step video instructions on obtaining data from topographic maps and constructing a topographic ...
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.

Mar 2, 2012 · Show me how to do this for this problem. Draw a horizontal line on the graph paper that is the length of your profile line. Draw vertical lines above your starting and ending points. Label the y-axis (vertical lines) with elevations, making sure that your scale goes from highest to lowest on your cross-section (see step 3).
