DescriptionThis app allows you to convert coordinates between many of the world's coordinate systems. It uses the PROJ4 library and a lookup file containing projection and datum parameters to support over 1700 coordinate systems. Lat/lon, UTM, US State Plane, and many, many others are supported. You can also add your own coordinate systems if you know the parameters. It either takes manual input or uses your current GPS location.
The entered coordinates can be displayed on a Google Map via a web browser with a single button press.

Permissions required: (1) GPS - to determine your location, (2) SD card access - to read and write user projections file.
Note 1: If editing the user projections file from within the app, make sure to close the app and re-select the coordinate system you've changed otherwise your changes will not be refreshed in the app.
Note 2: The convention used for the rx,ry, and rz values in the 7 parameter toWGS84 values may be different to some other software. If you experience a subtle difference in the results for a user projection which you create, try reversing the signs of these values.
