Freelancer Overview

I am a detail-oriented GIS and LiDAR specialist with hands-on experience in data labeling, annotation, and the preparation of high-accuracy datasets for machine learning workflows. My background includes 3D point cloud classification, feature extraction, segmentation, and manual annotation for large-scale infrastructure mapping projects, such as the Digital Technical Map of the Czech Republic (DTM CR). I am skilled in using industry-standard GIS tools like ArcGIS Pro, QGIS, and Panorama Editor, and have experience with LiDAR data processing and basic Python and SQL scripting. My focus on data quality, spatial data validation, and quality assurance ensures reliable training data for AI and computer vision applications.
