GeoStorm
There's very little public information about GeoStorm (Wikipedia even spells the name wrong as Geo-Storm), but I was able to get in contact with one of the developers, jake kolb v, through their resume/CV.
Their resume says the game was a "geo-location trainer" for the PC, made by Xeolux LLC/InVisM Inc.
They wrote the radar-simulation engine for GeoStorm, which they confirmed was only released internally to the training simulator's clients.
It did use the Spigot engine, and all UI & Gameplay were built by the Pipeworks team.
They also confirmed the game is unrelated to the later game GeoCommander that they also worked on, which has some videos on youtube (uploaded by them).
Information from Pipework's old page describes the game:
GeoStorm is designed to efficiently and effectively train strategic and tactical intelligence analysts and operators in an immersive, real-time environment. The simulation reflects analysis tools, techniques, signals analysis, and multi-agency collaboration strategies to improve analysis and operator skills and understanding so they can provide more responsive, relevant, and accurate support to warfighters and national decision makers.
