+ By BinaryEarth
The app either takes manual coordinate input or uses your current GPS location. The computed location can be displayed in Google Maps via your web browser with a single button press.
* Albers Equal Area
* Azimuthal Equidistant
* Equal Area Cylindrical
* Eckert IV
* Eckert VI
* Equidistant Cylindrical
* Equidistant Conic
* Lambert Conformal Conic
* Miller Cylindrical
* Oblique Mercator
* Oblique Stereographic
* Transverse Mercator
In addition to these projections, the app also supports affine transformations to allow you to set up local grid systems. See http://www.binaryearth.net/Miscellaneous/affine.html for details.
Online help for the app is available at http://www.binaryearth.net/WorldCoordSysToolHelp
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.

1.23 Added a link to the online help from the help dialog within the app.
1.22 Removed extra zeros from Ellipsoid and ToWGS84 parameters, Added more info about meaning of affine parameters to coord sys details page.
1.21 Added an affine parameters option to allow user creation of local grid systems.
1.20 Added support for oblique stereographic projection used in Lebanon (+proj=sterea)
