Users on MapCast with WMS compliant software can request an image that will match the screen resolution or scale of the software’s window. The request is sent through the Internet to the FBS servers where the image is generated and then returned to the user to be displayed in the software’s window. This action will count as one image, each time the user refreshes, pans or zooms in or out on the software’s window, an image will be generated and counted against the bandwidth monthly limit. The maximum image size returned by the service is 2048 x 2048 pixels.
