The question would be where to center it. That's an easier problem to solve in the typical case than Albers; you simply find the small circle that circumscribes the area of interest. That small circle's center coincides with the center of the optimal Lamber azimuthal equal-area for the region.</div><div><br></div><div>Regards,</div><div>— daan Strebe</div><div><br></div><br>On Feb 20, 2010, at 8:09:00 AM, OvV_HN <ovv@hetnet.nl> wrote:<br><blockquote style="padding-left: 5px; margin-left: 5px; border-left-width: 2px; border-left-style: solid; border-left-color: blue; color: blue; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="font-family: monospace; font-size: 11px; "><br>Noteworthy is the article:

<br><br><br>By the way, do you have a similar algorithm for optimal parallels for the
