<span style="font-size: 13pt;"><span style="font-family: Carlito;">G'day
there, </span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">all,<br>
<br>
QGIS just discovered. Oh. Wow.<br>
<br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">Jennifer of Chermside Oz here, with two
que</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">stions of a very generic nature.</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"> Sorry.<br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">Before I commit a big slice of my
remaining life-span trying to mistress GIS via Q, </span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">can I ask:</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"> 1/ is Qgis in tandem with any known DB
capable of providing me an accurate fine-grained result on the <span style="font-weight: bold;">area</span> of just the oceans, all of them,
360° round, that lie between the ancient Greeks Tropic zone, in my case
either <span style="font-weight: bold;">±45° lat or ±50°.</span> It's
the granularity that I n</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">eed.</span></span><span style="font-size:
13pt;"><span style="font-family: Carlito;"> </span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><span style="font-size: 13pt;"><span style="font-family: Carlito;"><span style="font-style: italic;">(2° grid good, tighter ideal.)</span></span></span></span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
<br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"> 2/ if </span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">Y</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">es, what
would be your rough assessment of the time it would take for this
tech-head, in Mac since Syst 0.9 ancient crone</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><span style="font-size: 13pt;"><span style="font-family: Carlito;">, </span></span>who
is not fluent in any code or language </span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><span style="font-size: 13pt;"><span style="font-family: Carlito;"><span style="font-size: 13pt;"><span style="font-family: Carlito;">to pull out
an answer</span></span>, </span></span>or</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"> 3/ again if Yes, and faster, is anyone
willing to give this poor pensioner <span style="font-style: italic;">(cue
the strings & harps) </span>a price on your digging out this dat</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">a?</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">This because I believe that after 20 years
of head scratching after the shock of first seeing the 200 year plot of
CO2 in the atmosphere, and being an old radio tech recognizing a +ve
feedbac</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">k curve, think that with my 5th concept<span style="font-style: italic;"> (four failures) </span>I've gotten a
winner that should stop ocean heating.</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">Reflecting enough incoming insolation back
out to level the EEI, and perhaps even reversing the heat build up. All
done with 98% reflective buoys launched at strategic points onto
passing currents, so they stay mostly in the Tropic zones. I need a
scientifically valid referable source of accurate areas data to calc how
many bouys are needed. All CC & open sour</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;">ce, so not
much followup cash flow.</span></span><span style="font-size: 13pt;"><span style="font-family: Carlito;"><br>
<br>
Hope someone can see a solution. Short of measuring my old 300mm
inflatable home globe!<br>
Google Earth has proved accurate to establish gross areas (+0.3%, my
measuring, 10° x 10° grids.)<br>
Need far better info, so as to not be dismissed out of hand.<br>
<br>
Cheers<br>
<br>
Jen<br>
