Marea helps estimating the area for a region given by a set of coordinates. Useful for plots, farm land, roof measurements and anything you can see with Maps.
The total area is calculated and given in several units, such as square meters, square feet, acres, hectares, square km and square miles.
Also available is the distance between each point.
Available as an In-App Purchase is the ability to save the areas, add notes, attach pictures, calculate a price by multiplying a value with the given area, and share as both an map image or a KML file.
Also provided as In-App Purchase is the ability to change to Google Maps. This allows for situations where either map is outdated in a particular area, or there's clouds in the imagery that makes it difficult to make out the various points that need to be measured.
Measurements do not take elevation and other minute aspects into account. This tool does not replace the need for an accurate professional survey.
