7.5-Minute Topo. 7.5-Minute Topos closely resemble historical 7.5-minute USGS map products as well as US Topo maps.. This large-scale map type provides a high level of detail over approximately 50 to 70 square miles per map and can be used for recreation and navigation (orienteering and geocaching), city planning, search and rescue, science studies such as geologic and geographic field work ...
- 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, ...

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.
