Map Radius Calculator. You can draw multiple circles, distances, areas or elevations, import/export data save and edit them later with a larger map! Draw a Radius around a map location. Draw a radius circle around a location in Google Maps to show a distance from that point in all directions.
Find the area of any simple shape on a map. Useful tool to find the approximate acreage or a tract of land, the square footage of a roof, or estimate of the area of something.
This online mapping tool measures the area of a circle and calculates its measurements in square meters (M²), square kilometres (KM²), square feet (FT²), square miles (MI²). It also calculates the circle radius distance in meters, kilometres, feet and miles.
Use this tool to draw a circle by entering its radius along with an address. You can also click a point on the map to place a circle at that spot. You can adjust the placement of the circle by dragging it to a different location.
I use pyproj to do this, but you can use whatever you want. Once you've transformed your long and lat degrees to x and y meters, Point(x, y).buffer(1.0).area is the area in m^2 of your circle (64-sided polygon to be precise).
3 kwi 2014 · I would like to draw a circle on a point with width in meter. To do that, I've tried to use the scale of the map. Assuming that scale = ft / pixel (i'm not sure that this formula is correct) And ft = m * 3.2808. sizeInPixel = sizeInMeter / MyMap.Scale * 3.2808; To draw the circle I use a class inheriting from polygon :
