Trends in Earth Observation Increasing need for detailed, up-to-date information as a basis for planning and decision making –

Increasing data volume

Increasing data complexity

Increasing demand for geo information

What’s New in eCognition 8.9 Christian Weise


eCognition 8.9 Highlights Land Mobile Feature Extraction Leverage eCognition to extract features from land mobile data in different views to combine best perspectives for both horizontal and vertical information extraction Extended Point Cloud Handling Increase analysis performance by applying temporary point cloud concept to enable efficient data access and processing without overwriting of source data Improved Rule Set Flexibility Build flexible rule sets or applications using all information types in different context & leverage state-of-the-art "Random Trees" machine learning algorithm

Land Mobile Analysis

Point Cloud Handling

8.9 Rule Set Flexibility


Land Mobile Feature Extraction •

Multi-perspective analysis 

Creates top down perspective map based on a camera view perspective map

Combines different perspectives in the feature extraction process to use the best view of the data for both horizontal and vertical analysis

Fuse image information (i.e. color) with point cloud information (i.e. elevation) into a streamlined multiperspective analysis

Camera Perspective

Top Down Perspective


Improved Rule Set Flexibility •

Random Trees 

Fully integrated Random Trees classifier (following Leo Breiman’s theory of random forests: http://www.stat.berkeley.edu/users/breiman/RandomForests/)

Remove need to work with external algorithms to save time and create a simple workflow

Rule Set Type Conversion 

Converting rule set item types to text and vice versa

Using rule set items independent of the type, i.e. Scene ID  Level name

Flexible information Sceneexchange Feature in Rule Sets or Architect solutions Scene Feature Scene Feature Name Object Double Feature Object Feature Name Map Name Class Name Layer Name Level Name

String

Scene Feature Name Object Double Feature Object Feature Name Map Name Class Name Layer Name Level Name


FloodMapper User Interface  Automated and semiautomated rule sets are combined in a library.

 Use of widgets together with a quick visualization of results and “undo” option allows for an intuitive selection of the parameters.

 Object information tools and graphics allow for deeper analysis of the data, if required.

Integration of Final Results into GIS, Cartography and Mapping

The results of the classification can be exported and directly integrated into any GIS environment


Summary  TerraSAR-X FloodMapper  Provides the customer with a fully-fledged solution to map flooded areas on the basis of TerraSAR-X data (in case TerraSAR-X pre-event data is not available, optical EO data can be used)  Is easy to install and operate  TerraSAR-X data are highly suited to map flooded areas (cloud coverage, geolocation accuracy etc.)  Data continuity is ensured via two satellites in orbit (TerraSAR-X and TanDEM-X)  Final products are according to general standards or customizable to specific requirements

Cadastral Change Detection – Landesamt fßr Vermessung und Geobasisinformation, Rheinland-Pfalz, Germany


Cadastral Change Detection  Project PI – Cadaster Administration Rheinland-Pfalz – Landesamt für Vermessung und Geobasisinformation, Rheinland-Pfalz, Germany

 Background – Excellent precise cadaster – But too “old” – Change detection based on aerial data time consuming (20.000 images)

 Goal – Semi-Automatic detection of changes – Optional adjustment of automatic processing – Consideration of changed input data – Definition of change  Area  Tolerance

– Easy to Use User interaction by means of easyto-use graphical user interfaces (GUI)

Existing Buildings Development Area


Cadastral Change Detection  Solution – Automated detection of building changes in cadastral data (building footprints vs. aerial photography and height data) – Extracted information – Buildings  New buildings  Changed buildings  Non mapping-relevant

– Vegetation  Elevated vegetation  Ground vegetation

– GUI for optional manual adjustment of automatic processing rules – GUI for visual quality assurance/control (QA/QC) and manual editing – GUI based on user requirements

 Data – RGB + NIR ortho-photos (0.2 m) – LiDAR DSM/DTM (1 m) – Building footprints (Vector)


Results– Architect Solution


Result– Example „448_456“ Change Classification Detection DSM RGB DTM ALK


Building and Vegetation Extraction Amt der Niederรถsterreichischen Landesregierung (Government Lower Austria), Austria


Building and Vegetation Extraction  Project PI – Amt der Niederösterreichischen Landesregierung (Government Lower Austria), Austria

 Background – Environmental Noise Directive of the European Parliament and Council requires up-to-date information about elevated objects for modeling sound-wave propagation – 20.000 RGB/NIR + Lidar (Lower Austria) – 60.000 RGB/NIR + Lidar (Austria) – Highly cost efficient and standardized

 Goal – Automatic LiDAR/RGB-NIR data processing – Automatic detection and classification of elevated objects – Buildings – Elevated Vegetation


Results – Accuracy & Next Steps  94,3 % for Buildings  96,1 % for Vegetation Verification area: ca 200 km²; Accuracy is the measure of "true" findings (true-positive + true-negative) divided by all test results

 Algorithm tested and works also on data – – – – – –
