Big update to reflect the learnings of https://gis.stackexchange.com/a/380449/172500

| Nov 11, 2020 at 22:12 | comment | added | poshest | @CL oh that sucks. What about if I exclude the top, above ~71 degrees and bottom, below about ~-55 degrees? Ie just grid out the middle doughnut? Does that make it any more possible? I guess suggested pattern has the problem of the circles bunching together the further they are from the equator. | |

| Nov 11, 2020 at 12:03 | comment | added | poshest | @CL I'm new to GIS so I'm not 100% certain. I want to use these coordinates to poll a WGS84-based mapping API (ie projected, right?) which uses query parameters lat/lon + radius, hence the circles. It seems to me that a "circle" plotted on any projected system would yield increasingly squashed circles on the actual globe the closer one gets to the poles. | |
| Nov 11, 2020 at 11:03 | comment | added | CL. | Do you want to do this in a geographic or a projected coordinate system (globe, or flat map)? | |

developed the problem with the "offset" rows observation
