4 Using the outputs
The content of the xml-file is mainly used for generating a beachball projection for the best estimated mechanism at the right place in space and time.
Additional information about the data and configuration used for the estimation of the result is contained and available as meta data.
- Beachball projection for an example source mechanism
Data visualization with the Web GIS
If an LP event is detected, analysed, and inverted, the result is shown by a beachball projection at the respective source point.
The basis for the projection is NED, the size symbolyses the magnitude, the colour shows the quality of the inversion result.
To the right, you can see an example for the mechanism

Metadata structure
The main metdadata structure (witten to an XML file) is as follows:
- <infrared volcano_id="0101-06=" project_id="ExuperyTest">
+ <range_upperleft>
+ <range_upperleft>
+ <start_datetime>
+ <end_datetime>
+ <processing>
+ <files>
+ <hotspots_overview>
+ <hotspots>
</infrared>
Within the <range_upperleft> and <range_upperleft> tags the coordinates (longitude and latitude) of the corners with their uncertanties are written. Similar case is for <start_datetime> and <end_datetime> tags.
