We had a piece of code, about raster data calculation in [login to view URL] the program runs for a long time, nearly a week. So we need to do some optimization, and we choice the Hadoop with Spark, now we had a PySpark environment and GeoPySpark extension. And now there is a Jupyter-notebook online, you can write code on it, I will provide original source code that does not optimized for reference. All you have to do is rebuild our original code using pyspark or geopyspark, our goal is 100x faster at least ==== 2019-04-10 12:08 UTC+8 ==== I have uploaded a new picture about my code, please check it.
