QGIS is not directly usable in Scala or Spark environments as it is a standalone Geographic Information System (GIS) application, installing and using it directly within Databricks may not be straightforward due to the specific environment and dependencies required by QGIS. For geospatial analysis within a Scala/Spark context, you might want to consider using GeoSpark, GeoPandas, Shapely or another JVM-compatible geospatial library.
