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, ...
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.
A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes and geographical names. The topographic map is a two-dimensional representation of the Earth’s three-dimensional landscape.
This lab is about how to use topographic maps to gain an appreciation of the three-dimensional landscape from a two-dimensional map. We will seek answers to such questions as: In which direction are we looking/going? How high is the land here? How steep is that slope? What profile shape is that hillside? How do we interpret topographic profiles?
A topographic map is a map showing the third dimension, elevation, graphically. In order to do that we display what we call contour lines, AKA elevation curves. Here is how to do that: Go to https://earthexplorer.usgs.gov/ and log in with your account; Delimit your zone of interest on the map
Mar 2, 2012 · Topographic profiles are used to understand what a topographic map is telling you in a specific area (or, you can think about it as giving you a "side view" of the landscape along a specific line on the map).
