how to measure distance in map?
Answers
Answer:
Use a ruler to measure the distance between the two places. If the line that you're trying to measure is quite curved, use a string to determine the distance, and then measure the string.
Find the scale for the map you're going to use. They are typically located in one of the corners of the map. It might be pictorial—a ruler bar scale, or a written scale—in words or numbers.
If the scale is a verbal statement (i.e. "1 inch equals 1 mile"), determine the distance by simply measuring it with a ruler. For example, if the scale says 1 inch = 1 mile, then for every inch between the two points on the map, the real distance on the ground is that number in miles. If your measurement on the map is 3 5/8 inches, that would be 3.63 miles on the ground.
If the scale is a representative fraction (and looks like 1/100,000), multiply the distance of the ruler by the denominator (100,000 in this case), which denotes distance in the ruler units. The units will be listed on the map, such as 1 inch or 1 centimeter. For example, if the map fraction is 1/100,000, the scale says inches, and your points are 6 inches apart, in real life they'll be 6x100,000 so 600,000 centimeters or 6 kilometers apart.
If the scale is a ratio (and looks like 1:100,000), you'll multiply the map units by the number following the colon. For example, if you see 1:63,360, that means 1 inch on the map represents 63,360 inches on the ground, which is 1 mile.
With a graphic scale, you'll need to measure the graphic, for example, white and black bars, to determine how much ruler distance equates to distance in reality. You can either take your ruler measurement of the distance between your two points and place that on the scale to determine real distance, or you can use scratch paper and go from the scale to the map.To use paper, you'll place the edge of the sheet next to the scale and make marks where it shows distances, thus transferring the scale to the paper. Then label the marks as to what they mean, in real distance. Finally, you'll lay the paper on the map between your two points to determine the real-life distance between them.
After you've found out your measurement and compared it with the scale, convert your units of measurement into the most convenient units for you (i.e., convert 63,360 inches to 1 mile or 600,000 cm to 6 km, and so on).
Simply click once on one point, then click again on the second point. The distance should then be displayed. You can click more than two points in order to build up a continuous route.
Use the miles / km / nautical miles / yards switch to measure distances in km or in miles or nautical miles. The Autopan option will move the map as you click the points.
The Search For Location text box allows you to quickly get to an area you wish without spending time zooming and panning to find it. For example if you wish to find the city of Rome in Italy, type "Rome, Italy" and then click Search. The map will then go straight to Rome. Note the "[city][comma][space][county]" format.
Toggle markers will show or hide the markers if they get in the way.
Clear last will remove the last point from the map
Zoom to fit will zoom and pan the map to get the best fit of all your points on as large a zoom as possible.
Clear Map is a reset button that will clear all points and allow you to start measuring a distance again.
You can edit the position of any existing points by dragging the marker (when they are displayed) and dropping the marker in it's new position
You can also adjust the height of the map to have it large, medium or small in size.
You can delete a point by right clicking on the
