GeoTrellis, GIS on Scala
3 likes615 views
This document discusses using Scala for geographic information systems (GIS) by leveraging Geotrellis and Spark to ingest, process, and analyze geospatial raster and vector data across distributed file systems and databases. It provides examples of computing zonal statistics, using space-filling curves like the Z-curve and Hilbert curve, and links to Geotrellis demonstrations for further information.
