Calculation of average speed or time spent. If asked in metres the answer would be 3300 metres. Drag the marker on map to calculate distance (km, meters, mile, foot) and bearing angle of direction on google map, between two points of the earth. Last but not least, the associated elevation profile. Then enter the time to calculate your average speed and know your performance. Automatically, the route will follow the road and calculate the distance traveled between the 2 last map points. If asked in kilometres the answer would be 3km., 300m. First, select on the map your start point or enter an address, city, region. Stretch the thread on the scale line, you will get the ground distance in kilometres and metres, writing the unit of measurement is always important e.g., if the distance calculated between two points is 3.3 km. Put the thread along the line touching as far as possible to measure and keep on marking with ink at turns till the last point. At the end of thread (close to knot) mark the point with pen at which you will begin to measure (point A). It has to be measured with the help of a strip of paper or thread e.g., to measure a river in a toposheet take a piece of thread make a knot on one end. This is how to draw a radius on Google Maps using CalcMaps. First zoom in, or enter the address of your starting point. Use the drop-down from the Radius KM tab to adjust the size of the radius. Note: To measure the distance on the google maps distance calculator tool. To measure a winding course route is complicated. Now select the area around which you want to draw the radius. Note down the distance on the map in centimetres then either with the help of the graphical scale which is provided below the toposheet or by using the statement scale distance can be measured in kilometres and metres.Į.g., two places are 5.6 km., apart on the map. The units will be listed on the map, such as 1 inch or 1 centimeter. 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. Keep the two pointed ends of the divider over line or two points which has to be measured and then carefully keep on scale. If your measurement on the map is 3 5/8 inches, that would be 3.63 miles on the ground. To measure the shortest distance between two points on the topographic map along a straight line can be done easily with the help of a pair of divider.
