❤ DESCRIPTION:
This talk by Noel Gorelick focuses on performance tuning in Google Earth Engine. He identifies common mistakes that slow down scripts and provides guidance on how to avoid them. Some key points include: using filterDate and filterBounds first, avoiding reduceToVectors, reproject, resample, and joins, and combining reducers. He also discusses the use of profiler, user group, and script link for debugging.
