<div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I had tried playing around with v.random and v.kernel to see if I could<br>
understand your problem, but I couldn't find any solutions so I didn't post<br>
it. But since you got upset with GRASS community, I will share what I found<br>
out anyway :)<br></blockquote><div><br></div><div>Sorry, I am not upset!! :-) I was genuinely wondering if I didn't describe my problem correctly or if I had posted to the wrong forum.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
I tried with different numbers of points and with different resolutions and<br>
I was amazed that you could make v.kernel work with 2.5 million points in a<br>
200 meter resolution with a 1000000 stdeviation!! My quadcore computer took<br>
so much that I gave up.<br></blockquote><div><br></div><div>Something must not be right with what I'm doing because, no matter how I skewed the options, it took less than 200 seconds to run on my 4 year old 1.6 GHz Intel Core Duo M processor (i.e., slow).</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I noticed that it goes slower with increasing resolution, increasing number<br>
of points and increasing stdev. I also noticed that you have to set a much<br>
higher stdev for smaller resolutions and that this value is by no means<br>
intuitive.<br></blockquote><div><br></div><div>Where is resolution adjusted? <a href="http://grass.fbk.eu/gdp/html_grass64/v.kernel.html">http://grass.fbk.eu/gdp/html_grass64/v.kernel.html</a> doesn't make that clear. Am I supposed to have a pre-made raster layer already that corresponds to my vector layer? </div>
<div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hope this helps (or at least, keep you in the list :) )</blockquote><div><br></div><div>I really appreciate your advice! I'm not upset with the list, was just afraid this was too esoteric or poorly stated.</div>
