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 generate 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 to design and to implement a JIRA custom plugin. The backoffice system handles about 8000 requests a DAY.

Software

Besides my customer projects I have developed some nice tools, that I'd like to share. They are either freeware or commercial. If you have any questions concerning this tools or you are in need of a custom tailored tool, don't hesitate to contact me.

 

The MicroStation Test Framework

microTest ist ein wikibasiertes Framework, um Black-Box-Tests( also nicht Funktions-, sondern Anwendertests) für beliebige Microstation-Programme(MDL/VBA) oder Microstation-Workflows zu erstellen und automatisch durchzuführen. microTEST ist ein unverzichtbares Werkzeug für Regressionstests und die Kommunikation zwischen Tester und Anwender.

 

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. 

 

Place Microstation cell from geoinformation stored in Exif-Header in your photos

GpsPhotoCells places a cell at the geoposition a photo was taken. Click the cell and the photo is shown. Can be used with any coordinate system.

 

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.

 

Runs a command every time you activate a template

You like the Microstation templates setting but you liked the good old settings manager even more. This tiny tool bridges the gap. Runs a command every time you activate a template.

 

Autoupdate your MDL/VBA Programs via Web

Enable your own MDL and VBA programs to be autoupdateable. Whenever the user starts your program it connects to a certain webpage, checking for the latest version. If the users verison is outdated, a dialog pops up informing about recent changes and requesting for download and installing.

 

Lock the raster position in the dgn

Are you annoyed by moving or scaling your raster accidentially in Microstation. rasterguard takes care for you.

 

Coordinate information for Microstation elements

Labels Microstation-Elements (all types, e.g. circle, lines, cells).

 

Generate shadows around Texts

Generate a shadow effect around texts, just like the css-property "text-shadow".
