PROFILE

Harald Kristen

Developed two geospatial user-defined functions for the fusedio/udfs repository, focusing on streamlining satellite imagery workflows. The first UDF automated downloading satellite imagery from ArcGIS ImageServer for specified bounding boxes using REST APIs, while the second converted standard TIFF files into Cloud Optimized GeoTIFFs to enhance storage efficiency and cloud processing performance. Leveraged Python, GDAL, and Rasterio to handle raster data and parallel processing, ensuring scalable and efficient data handling. The work addressed the end-to-end workflow from data acquisition to optimized storage, enabling faster downstream analysis and improved accessibility for customers working with large geospatial datasets in cloud environments.
