The part of me that screams deadline thinks maybe you toss it into
excel/calc and derive time then join that info back the distance
portion. The minute I finished that sentence that might work for a
few lines/distance - but you might have more than a few points/lines
in the problem. <br>

To quote a person I once knew "That's a thinker". <br>

<div>Yeah, I’ve got a distance reference that covers the amount
of distance covered in the time from the last point. I’m just
missing the way to actually do the calculation in the
program. I cant see a way to compare a point to the one
before it.</div>

<div dir=""> I can think of a couple of ways you might be able
to do this - but considering I haven't done something like
this before it's a guess. <br>
<br>
You can derive an interval in seconds I believe (referencing <a

target="_parent">http://nathanw.net/2012/06/30/better-date-and-time-support-in-qgis-expressions-and-styles/</a>)
from the point data - I'm assuming you have date and time (or
at least time). <br>
<br>
You could connect the points with a line (that would give you
distance). <br>
<br>
I'm thinking this might be better accomplished in a database
as opposed to a shapefile (assuming shapefile). <br>
<br>
...and I think I've just given you the most abstract assumed
non-answer ever. <br>
<br>
Lemme think on this one a bit more. Hopefully someone has a
practical answer. <br>

<div>Hi all,</div>
<div><br>
</div>
<div>I’m working on some point data that has been
collected using a combine in an agricultural field.
Trying to figure out a way to compare speed between the
dropped points? I’m not sure how to start….can anyone
help?</div>
