The best Android app for measuring any polygon. Just add your points directly by pressing the screen with gMaps or change the screen and enter the data from your topographic notebook to recalculate any polygon.

The App compensates the final coordinates obtained, using the Pennsylvania method, and indicates whether the unitary measurement error is acceptable or not (less than 0.003).

A complete PDF report is generated, with all the information, distributed in a series of tables. A TXT and DXF files are also generated in order to facilitate importation in any CAD program.

----------------------------------------------------

How to use the gMap screen:
1) Draw the points of your polygon by touching the screen.
2) You can capture your current position and delete the last point entered.
3) Once you finished drawing, press the Play button to perform analysis and generate the three files (PDF, TXT and DXF).


How to use the recalculation screen:
1) From the gMap screen press the "change screen" button. You will enter the recalculation screen.
2) The first point of the polygon is set by default in the coordinate (0,0).
3) You can add points by accessing the station entry screen, where you can see the start and end point of the current boundary.
4) Enter the distance and azimuth of each measurement.
5) When you reach the last boundary of polygon, select the option "yes" in "last point" so that the app recognizes the end point of the last boundary to the E-0.
6) When you finish drawing press the "Play" button to perform analysis and generate the three files (PDF, TXT and DXF).
