rasterstats's Introduction

Raster Stats

QGIS plugin, developed with the intention to provide a fast and easy-to-use tool for computing statistics on the overlap between raster and polygon layers.

Difference from other tools available in QGIS (as of its release)

In addition to the tools that already exist in QGIS for computing raster statistics, this plugin allows for the computation of histograms for zones and provides a wider range of summary statistics (Average,Median,Standard deviation,Variance,Minimum,Maximum number of pixels overlaping and median absolute deviation )

Key assumption

Pixels are fully included in a polygon, regardless of the total overlap. For this reason, care should be taken if the pixel size in the raster layer is relatively big when compared to the polygon size

rasterstats's Issues

Create version for QGIS 3

Upgrade the plugin to work with QGIS 3

Statistics are not computed for some polygons

Plugin does not compute statistics if the a polygon does not overlap completely the raster image, returning an error

Add N to reported stats

Could you add the nb of pixels to the reported stats? Also, if possible,
as you are reporting the median, could you add the mad (median absolute deviation),
https://en.wikipedia.org/wiki/Median_absolute_deviation
which is the robust estimator of the standard deviation (median,mad are the robust versions
of mean, std. dev).
