iUTM app for iPhone and iPad

iUTM™ is GIS application that provides conversion between universal transverse mercator (UTM) projection and geodetic coordinate for the specified reference ellipsoid.


Features:

- Conversion between geodetic and UTM projection coordinate systems.

- UTM zones lookup.

- Accounts for UTM zones overlap, can be turn on / off in the settings.

- Validates consistency of a UTM coordinate in To Geodetic conversion.

- Single entry for geodetic and UTM coordinates: automatic recognition and parsing of the entered format.

- Simple copy and paste exchange of data with other applications.

- Determines geographic coordinate of the current location.

- Supports three (3) geographic coordinate formats: DD (decimal degrees), DMS (degrees, minutes, seconds), and DM (degrees, minutes). Total of 22 format variations.

- Supports three (4) UTM coordinate formats.

- Supports five (5) distance units (meter, kilometer, foot, yard, mile)

- Supports 23 commonly used reference ellipsoids:
