GeoSimulator is a patent pending platform for development of location based solutions. Current development/testing methods requires deep knowledge of GIS computations. It involves handling complex GPX, KML files or dealing with limited locations in IDEs. Inevitably application developers spend more time in location functionality rather than business logic or user interfaces. GeoSimulator takes the location specific complexity out of the application development process with its simple few-lines-of-code integration. Apart from development, testing becomes simpler and cost efficient due to the fact that it can be done straight from the desk as opposed to field testing. The presentation explains all the salient features of this testing and development platform.
