<DIV><FONT face=Garamond>We are using GeoMoose 2.2. Our data
covers three states (Michigan, Minnesota & Wisconsin), so we have all
of our postgis data in WGS84. We want to
eventually view the data in webmercator, but we are concerned
with speed/performance because we would be reprojecting a lot of layers on the
fly. Currently we have over 200 layers with many more layers to be
added. Will reprojecting that many layers significantly effect
performance? Or would it be better to decrease accuracy in measuring
distance and calculating acreage because of the projection (WGS84)?
We would using the buffer tool for selecting waterbodies within a certain
distance. Any thoughts or suggestions would be greatly
appreciated!</FONT></DIV>

<DIV>Hm.. yes, there is. What version of GeoMOOSE are you using?
Is there any chance you can use a meters-based projection instead?
By doing the conversion from DD to a measure unit is a real fallacy
because it changes DRASTICALLY based on where on the planet the user is trying
to measure.</DIV>

[Geomoose-users] Setting buffer select units<BR></FONT><BR>
<STYLE></STYLE>
<DIV><FONT face=Garamond>Is there a way to set buffer select units different
than the ground units defined in the mapbook? I am using WGS84 (4326)
and would like to buffer select based on meters, feet or miles and not
degrees.</FONT></DIV>
<DIV><FONT face=Garamond>Any help would be greatly appreciated.</FONT></DIV>
