Hi, GIS users. I am struggling with extracting value from raster into each polygon. I have two layers, which are major crop raster and field boundary shapefile. I
TheExtract by Polygontool has an extraction area parameter with an outside option which allows cells outside the input polygon to be selected and written to the output raster. All cells inside the polygon receive NoData values on the output raster. However, this tool does not allow the use ...
exactextractprovides a fast and accurate algorithm for summarizing values in the portion of a raster dataset that is covered by a polygon, often referred to aszonal statistics. Implemented in C++, it is available through a command line interface as well as packages forPythonandR. More information...

raster-to-polygon conversiongeographical information systemIt is always computing intensive and time consuming to extract polygons from massive classified images. Although parallel computing can improve the efficiency of geographical data processing, the performance of the conversion suffers from the trade-...
