interesting. What is the problem with the white area? Is that in
the csv-file? It should be dark, not?</p></div>lucasnijstag:support.nodebox.net,2012-11-01:Comment/342227352014-09-03T16:12:57Z2014-09-03T16:12:57Zbasic mapping<div><p>Hi there. I guess it's related to the threshold values, in order
to make<br>
other parts visible, I had to tamper the values - colour range
values<br>
mostly if I recall well.<br>
It is not very accurate.<br>

itself, just csv info missing - quickgrid compensates lacking info,
and that is why there is a filled area in the screenshot.</p>
<p>The original csv data from the "moon" came from some topo
reconnaissance I made using ISA MapSat from the Kerbal Space
Program game (<a href=
"http://wiki.kerbalspaceprogram.com/wiki/ISA_MapSat">http://wiki.kerbalspaceprogram.com/wiki/ISA_MapSat</a>);
I didn't collected enough data from that area (if you check the "z"
querie you'll find some zeroes)</p>
<p>If you run the other CSV data attached (dadosNV) you'll render a
nice complete map.</p>
<p>The threshold values I mentioned earlier are basically the
"alpha" and "range" of the gray_color node; you can define some
"blur" and "gamma" with them.</p>
<p>I'll try to think on adding countours one of these days, that
would be nice.</p></div>Rodolfo Oliveiratag:support.nodebox.net,2012-11-01:Comment/342227352014-09-05T13:20:48Z2014-09-05T13:20:48Zbasic mapping<div><p>Ok. I used a "convert range" node to convert the big numbers to
a 0-255 range. Because of the huge difference in size, and because
there is a lot more data in the light areas, you have to play with
those numbers. Which made us think about different ways of
distribution in converting numbers to other ranges. Kind of gamma
correction.<br>
Thanks for sharing this.</p></div>lucasnijstag:support.nodebox.net,2012-11-01:Comment/342227352014-09-05T16:46:37Z2014-09-05T16:46:37Zbasic mapping<div><p>I didn't remember to convert the range, nice idea.<br>
Anyway, glad that my endeavors are useful.<br>
