>>  G'day there, all,
>> 
>> QGIS just discovered. Oh. Wow.
>> 
>> Jennifer of Chermside Oz here, with two questions of a very generic nature. Sorry.
>> 
>> Before I commit a big slice of my remaining life-span trying to mistress GIS via Q, can I ask:
>> 
>>     1/ is Qgis in tandem with any known DB capable of providing me an accurate fine-grained result on the area of just the oceans, all of them, 360° round, that lie between the ancient Greeks Tropic zone, in my case either ±45° lat or ±50°. It's the granularity that I need.  (2° grid good, tighter ideal.)
>> 
>>     2/ if Yes, what would be your rough assessment of the time it would take for this tech-head, in Mac since Syst 0.9 ancient crone, who is not fluent in any code or  language to pull out an answer, or
>> 
>>     3/ again if Yes, and faster, is anyone willing to give this poor pensioner (cue the strings & harps) a price on your digging out this data?
>> 
>> 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 feedback curve, think that with my 5th concept (four failures) I've gotten a winner that should stop ocean heating.
>> 
>> 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 source, so not much followup cash flow.
>> 
>> Hope someone can see a solution. Short of measuring my old 300mm inflatable home globe!
>> Google Earth has proved accurate to establish gross areas (+0.3%, my measuring, 10° x 10° grids.)
>> Need far better info, so as to not be dismissed out of hand.
>> 
>> Cheers
