Geo Projects

2015 - 2020 Lead developer "geoservices" at on-geo GmbH

Greenfield project: Creation of a backoffice-System that automatically or semiautomatically generates real estate analysis reports for individual addresses. The portfolio consists of over 150 different reports. To generates those reports, the system gathers and combines data from a wide range of data sources, e.g. OpenData Sources, WMS-Sources, statistical data or prearranged databases. The system is embedded in a JIRA system, which structures  the work and makes it trackable. Part of the work was designing and implementing a JIRA custom plugin. The backoffice system itself handles actually about 8000 requests a DAY.

2008 – 2012 Team member of a scientific research team

The aim of that project was to establish a mobile early warning system for volcanic unrest to support local decision makers. My part was the frontend- and database design. The system gathers information from different data produces, like satellites or gps advices and displays them as thematic maps. The focus was to build a browserbased frontend, that has easy, intuitive handling without losing information.

Loading and Saving Spatial data into and out of Microstation

spatialgateway allows you to retrieve geosaptial data from different datsources and display them in Microstation. spatialgateway is fully integrated into Microstation, streaming the data seamlessly while changing viewport, zoom, level, etc. The display styles  are applied using a powerful XML-based ruleset. This birectional ruleset even allows to write back elements into the data source. 

`

Scriptable event engine for any kind of Microstation events

elementevents delivers a powerful framework, to release user-actions (either keyins, VBA-Functions or MDL-Funtions) for any kind of Microstation events. You are able to individually address any kind of element modification, viewport changes, element visibility, etc.
