11 Local Tasking Example

12 Local Tasking Example: 12 zones to be collected within 1 pass sites to collect sites to collect

13 Local Tasking Example: System schedules automatically a selection of zones 3 hrs prior to pass Automatically scheduled images

14 Local Tasking Example:.. But lets have a look at the real time weather.. ground fog! 3 hrs prior to pass Real-Time Weather

15 Local Tasking Example:.. and the clouds are moving cloud free Dissolving ground fog 2,5 hrs prior to pass cloud front!

16 Local Tasking Example: Last minute changes due to the dynamic weather situation. move strip! cloud free Dissolving ground fog move strip! 2,5 hrs prior to pass cloud front!

17 Local Tasking Example: Last minute changes due to the dynamic weather situation. clouds emerge! still cloud free 2 hrs prior to pass cloud front!

18 Local Tasking Example: Last minute changes due to the dynamic weather situation. clouds emerge! cancel still cloud free cloud free 1,5 hrs prior to pass

19 Local Tasking Example: Last minute changes due to the dynamic weather situation. cloud free 1 hrs prior to pass cloud free cloud free

20 Local Tasking Example: Last minute changes due to the dynamic weather situation. cloud free schedule? 1 hrs prior to pass start imaging here

21 Local Tasking Example: Final scenario ready to be uplinked to the satellite! scheduled scheduled scheduled 0,5 hrs prior to pass scheduled Manually scheduled images

22 Local Tasking Example: All automatically scheduled images would have been cloudy cloudy! cloudy! cloudy! Automatically scheduled images All images cloudy! cloudy!.

23 Local Tasking Example: All manually scheduled images were cloud free! 0,5 hrs prior to pass scheduled scheduled scheduled scheduled Manually scheduled images All images cloud free!

27 Main constraint: Weather & Time Weather Situation in Europe / Serbia May 2016

28 Acquisition on the 19 th of May: collecting in between the clouds ~8000 km² of Imagery although a very unstable weather situation

29 Local Tasking for the Serbia 2016: One day Example Imagery acquired on one day Camera Pointing on Ground Overflight / Nadir of the Satellite ~ km² Imagery with one overflight

30 Progress of the Project over the time

31 Project Results 100 % area covered Less than 5% clouds >20% of the coverage with 30cm data <80% of the coverage with 40cm data

32 Emerging Trends in the Earth Observation Business satellites currently orbiting the planet increase of 4.39% compared to this time last year. 221 satellites were launched in 2015 only operational satellites Earth observation/science with 374 satellites

37 WorldView-3 at a glance Improved Resolution higher resolution means you can see more detail in WV3 imagery. Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m short-wave infrared and 30-m CAVIS bands. At 20 degrees off-nadir, the resolution is 34-cm panchromatic, 1.38-m visible and near infrared and 4.1-m short-wave infrared. Additional Spectral Bands 8 bands of visible and near-infrared data; 8 shortwave infrared bands which are crucial for geological studies; and 12 CAVIS bands to detect water vapor, dissolved aerosols, snow, clouds and more. accuracyġeographic Better Positional Accuracy with accuracies of 3.5-m CE90% or better WV3 has no rivals for its enhanced positional
