routines to display scanned raster maps such as CADRG (compressed arc digital raster graphics) with simple stick routes drawn on top, but the easy to use software was popular with the end users and more functionality was added. Each additional feature was developed with significant input from the user community and improved with feedback from a group of beta testers. Unlike most other DoD developed applications, the FalconView development team was given very general requirements by the ANG which were fleshed out into a product by the development team and mission planners who used the software for their daily activities. Development and improvement of FalconView features is still strongly driven by its user community. Additional sponsors In the early years the software was distributed to other services from user to user because it made their jobs easier. As the program matured, United States Special Operations Command adopted PFPS and added capabilities such as the Moving Map functionality (ability to have the map scroll and rotate based on the position information received from a connected GPS navigation device) and helicopter support. In 1997, the United States Air Force adopted the Portable Flight Planning Software into the Air Force Mission Support System (AFMSS) program, followed by the first Navy release in 1998 and an Army release in 2002. Each adopter of the software has funded new functionality to the program and a corresponding expansion of its ability to interact with other systems. Version 3.2, released in 2002, added significant third party programmer support to FalconView. As a result, many new applications were developed by other government program offices and end users who used Visual Basic to automate tasks for their specific needs FalconView supports a set of programmer interfaces which allow applications to fuse their information into a single picture of the user's area of interest. The users know that data produced on FalconView can be shared with other branches of the armed services and coalition partners who have PFPS through the Foreign Military Sales Program. Open-source software Because the federal government has funded the development of FalconView, it is a nonproprietary "government off-the-shelf" (GOTS) application and is free of any license fees for government use. This includes the use of the Software Developers Kit (SDK) which documents the interfaces for use by government developers and contractors working on government programs. In late 2008, Georgia Tech was funded to develop and deploy
