However, I had to alter the mpCenterLatF/mpCenterLonF settings a bit from the projection origins. I do not know why the alteration was required, as usually one can set the projection origins and all is well. Thus, you might want to alter the settings a bit on your own (lines 41-42) to see if you can get a better fit of the data to the map. </div><div>Good luck,</div><div>Adam</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jun 3, 2022 at 1:44 AM James Ciarlo' <<a href="mailto:ciarlo.james@gmail.com" target="_blank">ciarlo.james@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi Adam,</div><div><br></div><div>Thanks for your reply.
