<p>Hi,</p>
<p>You could use the zonal Statistics in processing. You would need
to raster with different zones.</p>

<div>I find that I need to be able to select a small area of a
raster image in QGIS and have it calculate basic stats such as
max, min, average, and median. I cannot seem to find any
function to do this or a plugin to do it. Am I missing the
functionality somewhere? I would need to do this hundreds of
times as I examine peaks in magnetometry data to help classify
the features. Those values would then be added to a table of
features.</div>
<div><br>
</div>
<div>If this is not an available feature does anyone know how to
quickly implement it? I haven't written any raster plugins
yet. All my others are vector related.</div>
