iTM app for iPhone and iPad

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

Features:

- Conversion between geodetic and TM projection coordinate systems.

- Single entry for geodetic and TM 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 five (5) distance units (meter, kilometer, foot, yard, mile)

- Supports 23 commonly used reference ellipsoids:

Examples of the recognized geodetic coordinate formats:
DD (decimal degrees) format: 34.848735, -122.03118
DMS (degrees, minutes, seconds) format: 34 50 55.446 N, 122 1 52.25 W

Examples of the recognized TM coordinate format:
-632.51, 5311.56

Note:
To achieve the high accuracy results (+/- 1 centimeter) conduct conversions within 4° of the central meridian.
