Pay as you go
You pay per calculation with credits, the value of which varies with calculation radius and resolution so
a big calculation costs more credits because you are using more CPU time, memory and disk space on the servers.
Credits and Radius
One US dollar buys 100 credits. Ten dollars buys 1000 credits.
With medium resolution, 1km radius equals 1 credit so 100 credits can let you do either a single 100km radius calculation or 5 20km calcs.
Credits and Resolution
Selecting high resolution doubles the price. Selecting low resolution halves the price. 100km at high res costs 200 credits. At low res it costs 50 credits. Each resolution level has a memory limit so high can only be used up to 30km, medium up to 100km and low up to 200km radius.
Free calculations
Small calculations are free. They're handy for allowing you to test and adjust settings on a small scale before spending money and going large with the radius.
