Slide 2 (HALO Mission Support System)

Outline

• Motivation for a “Mission Support System”

• Objectives

• Concept

• Benefit for HALO campaigns

• Request for feedback


Motivation: Current situation

• Numerical forecast models, satellite and radar data, and observations yield large amounts of data to be explored.

• Additionally, tools for specific tasks (statistical computations, specific numerical models, ..) are in use.


Current situation: Data Integration

• Difficult to compare different visualisations.


Current Situation: Limited Interactivity

• Which fields are visualised on a map has to be specified in advance (prior to the campaign).

• Map region is fixed, interactive zoom & pan is not possible.

• Additional plotting of, e.g., planned flight tracks is complicated.

• Example: ECMWF forecasts are currently available as precomputed graphics from a DLR website.


Motivation: Summary

Shortcomings in the areas of:

• Interoperability.

• Integration.

• Interactive visual data exploration.

• On demand processing and simulation.


Objectives of the Project

Investigation of information technology methods that make the

• flight route planning and optimisation• visual data exploration (forecasting)• analyses and simulation control• communication• real-time monitoring of aircraft and instrument

status

processes easier, faster, and in some parts possible at all.

Scientists can spend their time more efficiently on actual scientific issues.

Scientific quality will be improved at lower costs.


Scenario: Interactive Flight Planning

4) overlay additional data fields, e.g. NWP or OpenStreetMap

1) 2D view of map

2) plan horizontal component of flight track

3) first estimates of flight performance


Interactive Flight Planning: Tilted View

2) NWP curtain;simulated data such as Lidar

3) flight manoeuvres

4) flight performance

1) adjust height


Interactive Flight Planning: Combined Views

1) Synchronized views: If the flight path is changed in one view, the other is automatically updated.


Interactive Flight Planning: Output

1) 2D map of flight track2) list of waypoints3) list of flight manoeuvres

Concept: ECMWF + 3D + OGC Standards

• Basis: ECMWF software (cooperation).• Usage of standards from the Geographic Information Systems

(GIS) domain for interoperability.

• Investigate fully four/five-dimensional visualisation methods.• Find suitable ways to couple tools with web service standards.

• Goal: Keep the system modular, transparent, and conform to standards.

→ Make it easy to integrate new tools and data sources.

Expertise TUM.3D

● Interactive visual exploration of large 3D data sets.– Scalars, vectors, tensors

● Combination with real-time simulation.– Computational steering

● Implementation on graphics processors.– Efficient parallel algorithms

● Application oriented.– Geoinformation-systems– Flight simulators– Medical simulations– Virtual windtunnels

Research areas


Expertise TUM.3D: Interactive Visualisation

Realtime visualisation in geoinformation-systems● Digital height fields and multimodal data


Expertise IfGI: Web Services

• Without standards:– No common data and meta data model.– No common interface specifications.

Sensor = Data source(model, satellite, HALO measurement, ...)



• Using standards:– Well defined data and meta data standards.– Well defined interface specifications.


Expertise IfGI: Uncertainty Visualisation

Use the information of the whole ENSEMBLE forecast. Example: Where can I be sure to get cloud free sky?

ENSEMBLE forecast

Interactive exploration of joint information


Benefit for HALO Campaigns

• Flight planning tasks become easier, faster, and more efficient, thus reduced complexity of the flight planning process.

• Standardized interfaces allow for– quick and easy integration of new tools and data

sources.– close coupling between MSS and HALO database.

• MSS data can be viewed on board of HALO.

• The MSS software environment can also be used for data analysis purposes after a campaign.

• Potential to improve overall scientific quality.


Realistic Achievements in 36 Months?

• Cannot develop a system with all-encompassing functionality.

• Objective:– Find methods for mission planning that are well suited

for HALO campaigns.– Implement prototypic software infrastructure.– Make software available as open source to all

scientists involved in future HALO campaigns.

• Focus on application scenarios motivated by the requirements of HALO demo missions.

Visualisation: Data Sources

1) If data is available locally, render locally.If not, import 2D section (horizontal/vertical) from web map service.



• Challenges:– Specialization / restriction of standards to special

needs.– Stay conform to standards.


Motivation: Summary

Shortcomings in the areas of:

• Interoperability.• Product integration.• Interactive visual data exploration.• On demand processing and simulation.

With increasing complexity flight planning will benefit from:

• Advanced visualisation (3D, uncertainties).• Computational steering.• Data mining to aid manual data exploration.


Vision

An easy to use website provides results from the planning process: visualisations of forecast and observational data, planned flight tracks, results of analyses carried out by the core planning team.

Mission Support System

user

An application provides extensive visualisation options for all sorts of data – ranging from standard views to 3D display. Flight tracks can be planned interactively. Analysis methods and processing services such as flight performance, the computation of trajectories or the simulation of expected lidar measurements can be controlled interactively. Results can be prepared for presentation and submitted to flight operations.
