NMEA is a standard which is widely used for representing GPS position information in textual form. This standard defines a set of one-line sentences which are independent from each other and contain information such as position, velocity and time.

Given the broad range of applications which are capable of understanding NMEA data, I decided to create a tool for manually drawing a path on a map representing an object or person moving around while carrying a GPS device which gives them their current position at regular time intervals (e.g. once every second). This path can then be stored as an NMEA file, i.e., as a text file containing NMEA sentences which represent the position information for all points in the path.

The tool is called NMEA Generator. I hope you will put it to good use, and should you have any questions, please don't hesitate to write a comment below or send me an e-mail. Enjoy it! :-)
