CV

WebGIS Developer

Institute of Geography and Geology, University of Greifswald

• Developing a WebGIS for tourism (historical maps, photographs documents): https://tegrys.geo.uni-greifswald.de/ (in development)
• Preprocessed scanned maps with python (reprojection, format conversion, mosaic with rioxarray, GDAL) and QGIS (georeference)
• Created basemap from OpenStreetMap vector data with scale-dependent styling in QGIS, exported as XYZ tile pyramids and host the resulting basemaps as web services
• Managed geospatial data in ArcGIS Online and integrated web services into the map frontend via ArcGIS APIs;
• Built frontend with WordPress, developed on Linux with Git and Docker

GIS and Remote Sensing analyst

Institute of Geography and Geology, University of Greifswald

• Maintained large-scale satellite datacube using FORCE
• Analyzed spatial vector, raster data with Python (GeoPandas, Rioxarray, NumPy, GDAL) and LiDAR data with R (sf, terra, lidR, rgdal)
• Performed drone-based data acquisition (spectral, RGB, LiDAR data)
• Processed drone data with Agisoft Metashape, DJI Terra

Intern

Thünen Institute

Large-scale forest inventory based on ALS point cloud

• Developed methods to derive individual tree attributes from ALS point clouds using R (lidR, rLiDAR, TreeLS). Achieved 78% tree detection rate in 4584 km2 of heterogeneous forest in North Rhine-Westphalia state, Germany
• Evaluated statistically models for tree attributes using R, attaining 0.86 R2 for tree height estimates and 0.74 R2 for DBH estimates

GIS and Remote Sensing technician

Centre for Econics and Ecosystem Management, Eberswalde University

• Implemented Random Forest algorithm using Python with Landsat 8, Sentinel 1, and Sentinel 2 data, using multi-temporal metrics (NDVI, NRPB, VV, VH, etc.). Achieved 91% overall accuracy for crop type classification in Central Asia (publication)
• Collected and digitized on-screen ground truth data for land cover classification using QGIS, Google Earth
• Produced maps, figures and statistics with R (dplyr, ggplot2) and QGIS
