Coordinate Master v7.7 [Paid]
Requirements: 4.0+
Overview: This powerful geophysics app allows you to convert coordinates between galore of the world’s coordinate systems, calculate geoid offsets, and estimate the current or historic magnetic field for any location. It besides includes measurement tools to calculate the point scale factor and grid convergence.

The app uses the PROJ4 library and a search file containing projection and data point parameters to support over 1700 coordinate systems. Lat/lon, UTM, US State Plane, and galore, galore others are supported. You can besides create your own coordinate systems if you know the parameters.The app besides supports affine transformations to allow you to set up local grid systems. See http://www.binaryearth.net/Miscellaneous/affine.html for inside information.

The app either takes manual coordinate input or uses your current GPS location. The calculated location can be displayed in Google Maps via your web browser with a single button press. It besides supports MGRS grid references.

You can export any lat/lon, UTM or cross Mercator coordinate systems to a HandyGPS data point (.hgd) file for use as a custom data point in HandyGPS.

The magnetic field calculator page calculates the Earth’s current or historical magnetic field at a given location. The magnetic declination calculated is useful for compass navigation since it represents the difference between true north and magnetic north. Field inclination and total intensity are besides calculated. This tool uses the International Geomagnetic Reference Field model (IGRF-12). See http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html for full inside information. Years from 1900 through to 2020 are supported.

The app can besides calculate the geoid height offset for a given location, exploitation the EGM96 model. Geoid offset can be subtracted from the height according by GPS to give your actual height above sea level.

Online help for the app is available at _http://www.binaryearth.net/CoordinateMasterHelp

NOTE: A version of this app is now besides available for iPhones.

Permissions required: (1) GPS – to determine your location, (2) SD card access – to read and write user projections file.

Whats New:
7.7: Allow Coordinate Master to handle “geo” intents via the Android share menu.
