<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hey Andrew,<br>
<br>
My conventional scan is simply iterating over each point in the pointview (represents all points in the file), latching min and max UTM E,N. I wrote a small test and it turns out that the StatsFilter does indeed return the exact same bounds as the scan. So
I must have wires crossed somewhere else. <br>
<br>
Thanks anyway,<br>

<br>
I constructed a reader pipeline with a StatsFilter to determine the geographic bounds of a LAS file. The minimums and maximums (X, Y, Z) however were not the same as those that I latched in a conventional scan over all points. In fact, there were points over
ten meters beyond the boundaries determined via StatsFilter. Does StatsFilter take a statistical sampling of points so that extremes might be missed? Is there some property I should set to make sure all points are considered?</div>

<div>The stats filter does not statistically sample. The behavior you're describing seems incorrect. I'd need more information to investigate. If you have a small file you could provide, I could look. I'd also need to know how you "conventionally scanned"
the points.</div>
