Abstract: 

We report on our development and implementation of a graphical 
"programming" interface for a sensor network tasking language called 
STEP. The graphical interface allows the user to specify a program 
execution graphically from an extensible pallet of functionalities and 
save the results as a properly formatted STEP file. Moreover, the 
software is able to load a file in STEP format and convert it into the 
corresponding graphical representation. During both phases a 
type-checker is running on the background to ensure that both the 
graphical representation and the STEP file are syntactically correct. 
This project has been motivated by the Sensorium project at Boston 
University. In this technical report we present the basic features of 
the software, the process that has been followed during the design and 
implementation. Finally, we describe the approach used to test and 
validate our software.
