I.- The program:
UTeMization is a guide user interface (GUI).
The program transforms geographic coordinates (longitude and latitude in decimal format) to UTM coordinates (in meters) using the Coticchia-Surace formulation*.
22 different ellipsoids can be used, including WGS84, of course.
The interface is very simple. It is possible to transform a single point or a list of points.
II.- How it works:
Single point transformation is done directly introducing geographic coordinates in a text box and pushing a button. The resulting UTM coordinates are shown in other text box.
Lists should be introduced in ASCII files (txt, for example) organized in columns. First column is the longitude, second column latitude. The file can have more columns with extra data (elevation, for example). Results are written to a file, with or without the additional data.
III.- Format of data
The only condition for single- and multi-point transformation is that geographic coordinates must be in decimal notation. This is, in decimal degrees with signs, no letters. Examples:
- YES: -36.584747
- NO: 36º35’05.09’’ W
IV.- Running and editing
The code is composed by two files:
- utemization.m
- utemization.fig
For running just write “utemization” in the command window.
Both files must be in the same directory (current directory or added to the path).
The .m file contains all the routines, and the .fig file the window. For editing them the best way is by typing “guide” in the command window and opening the .fig file.
