It looks alright to me. The moving average algorithm searches (for each pixel) for points within the specified radius, and then averages the values of all those points. "gdal_grid" also supports inverse distance or linear interpolation if you want a more smooth result. It is perhaps surprising

[gdal-dev] Wondering gdal_grid moving average interpolation

I'm translating things on QGIS and now looking at GDAL tool rasterizing point data set with moving average interpolation. That's making a call to gdal_grid with -a average. I've got the attached result from a point set (circles with red border and inside inverse grayscale with interpolated
