This powerful geodesy app allows you to convert coordinates between many coordinate systems around the world, calculate geodetic offsets, and estimate current or historical magnetic field for any location. Also includes a calculator as well as surveying tools to calculate point scale factor, grid convergence, reflection, reflection and sun angle. You can also store multiple points and calculate the length and area of the border, or import / export to CSV files.
The application uses the PROJ4 library and a search file containing drop and datum parameters to support over 1,700 coordinate systems. Lat / lon, UTM coordinate systems, US coordinate systems (including US state aircraft), Australian coordinate systems (including GDA2020), UK coordinate systems (including commanded surveying ) and many more are supported. You can also create your own coordinate systems if you know the parameters. The app also supports affine conversions to let you configure local network systems. See http://www.binaryearth.net/Miscellaneous/affine.html for more details.
The app manually enters coordinates or uses your current GPS position. The calculated location can be viewed in Google Maps through your web browser with the click of a button. It also supports MGRS network credentials.
You can export any Lat / Lon, UTM or transverse Mercator coordinate system to a HandyGPS reference file (.hgd) to use as a custom reference in HandyGPS.
The Magnetic Field Calculator page calculates the current or historical magnetic field of the Earth at a specific location. The calculated magnetic declination is useful for compass navigation because it represents the difference between true north and magnetic north. The slope of the field and the total intensity are also calculated. This tool uses the International Geomagnetic Reference Field Model (IGRF-13). See http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html for more details. Years 1900 to 2025 are supported.
The app can also calculate the geoid height offset for a specific location, using the EGM96 model. The geographic displacement can be subtracted from the altitude reported by the GPS to give your actual height above sea level.
The app also includes a solar angle calculator which can be used to calculate the position of the sun in the sky at any location and on any date and time.
Online instructions for the application are available at http://www.binaryearth.net/CoordinateMasterHelp
A version of this application that enables mass coordinate conversions is now available for Windows. See http://www.binaryearth.net/CoordinateMaster/Windows
