NOTE: OnScene Xplorer 4.0 is for users registered with Iron Compass Map Co. OnScene Xplorer 4.0 is design for fire fighters, EMS, and law enforcement to provide search for locations, route guidance, pre-incident planning, and hydrant management. OSX 4.0 syncs between devices and display vehicles locations when an internet connection is available and the asset is configured (very easy to do). OnScene Xplorer 4.0 mapping is "local" on each device, no internet connection is needed to use the app and mapping! An internet connection is necessary to access other map styles like "air photos". But being "local" is great for areas with limited cellular coverage or devices without cell service....or you just don't want to pay for cell plans in each vehicle. Add pre-incident facility plans with rich information, photos, and floor plans. Manage your fire hydrants and display hydrants base on NFPA flow-ratings. Add "map markers" from a large list of symbols gain situational awareness faster.
