14 Tasking Example: 1st Schedule with Real-TimeWeather Overlay

15 Tasking Example: Schedule Editing

16 Tasking Example: Final Schedule 30 Minutes before Pass

17 Collection Example: Optimized (=minimized) cloud cover

18 Summary IKONOS satellite imagery is an excellent VHR solution for large area mapping projects time critical collections Local collection scheduling and satellite tasking allows for last minute weather changes to be included greatly improves cloud free data collection results guarantees faster data availability IKONOS has the highest collection rate of all current multi spectral VHR satellites IKONOS local data downlink allows for same-day delivery for time-critical applications

cloud free data collection results guarantees faster data availability IKONOS has the highest collection rate of all
