Changes

From this, the optimum density -- the point at which the change in total density gives no further growth effect is probably between 2 and 3 startups per hectare. We will split the difference and use 2.5 startups per hectare as the optimum for the our innovation district simulations.Given than 0.001 decimal degrees is 111.3199m, there are 0.000898 degrees/hm [http://wiki.gis.com/wiki/index.php/Decimal_degrees]. We'll use square boxes, so our corners will be: coord +/- ( ( (sqrt(x)/2)*0.000898) / 2.5) Note that we had one too many decimal places in the earlier version by accident, which is why everything looked really weird!
