Polina Lemenkova

Computational geoscientist, researcher in geoinformatics and Earth observation.

This account hosts the source code accompanying my scientific publications: scripts, data and figures for reproducible processing, analysis and cartographic visualisation of geospatial data. Repositories are named by method and study area and are linked to the corresponding peer-reviewed articles.

Research areas

  • Satellite image processing and land-cover classification from Landsat OLI/TIRS time series
  • Machine-learning classification for remote sensing (Random Forest, SVM, MLP/ANN, Decision and Extra Trees, gradient boosting)
  • Marine geophysics, bathymetry and geomorphometry of ocean seafloor
  • Cartographic scripting, terrain modelling, seismology and geohazard assessment
  • Reproducible processing pipelines and cloud geoprocessing (Google Earth Engine, PySpark)

Languages and software

Python, R, Octave/MATLAB, Shell (bash, AWK). GMT and pyGMT, GRASS GIS, GDAL/PROJ, QGIS, scikit-learn, ObsPy, rasterio, terra, earthpy, ggplot2, seaborn, GEE, Apache Spark (PySpark).
