MyMeasure

Measure length, perimeter and area on a map.
Using an interactive cross hair you can trace the outline of any feature visible on the map, creating a series of connected points the area and perimeter are continuously updated. The cross-hair includes a radius indicator that can be scaled dynamically to quickly size features on the map whilst tracing.
Works with anything you can display on the map from the size of a continent, down to something as small as a car. Extremely complex shapes can be handled with virtually no limit.
Comes with sample reference tracks to give you confidence in the accuracy and power of this app (for example race tracks and sports arenas whose dimensions can be found on the web). Samples provided include Indianapolis Race Track, The Nurburgring, Old Trafford Football Pitch and the outline of France.
Measurements can be saved locally as tracks and then can be opened and viewed within the app or can be emailed in KML or Microsoft Excel format. The email message also includes a summary of the dimensions and a picture of the track.
Can be switched between Metric and Imperial units (hectares, sq.km. sq.m, acres, sq.miles, sq.yrds, sq.ft) at any time, and can be switched from measuring areas to simple lengths.
You can zoom to your current location, search for an address, or manually pan/zoom to any place in the world.
A useful tool for anyone who needs to calculate these dimensions quickly and on the move, also fun for anyone just interested in how big things are.
