This tool requires projected data to accurately measure distances. 5 Don't just take averages. In geography, the centroid of the two-dimensional shape of a region of the Earth's surface (projected radially to sea level or onto a geoid surface) is known as its geographic centre or geographical centre or (less commonly) gravitational centre. Geographical distance is the distance measured along the surface of the earth. This week, researchers at the Harvard Geographic Insights Lab launched the first-ever dashboard that tracks life expectancies on the U.S. Congressional District level.

Another way to calculate the geometric mean is with logarithms, as it is also the average of logarithmic values converted back to base 10. If all the points are within 30 meters of each other, just averaging the latitudes and longitudes will be very close to the "true" geodesic center for any reasonable definition of "center". A world leader in geography, cartography and exploration. Declination is positive east of true north and negative when west. It looks like it wants to import your geodata in GeoJSON format.
