[Geomoose-users] Setting buffer select units

[Dara Olson]

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!
Miigwech!

  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.

    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.
    Any help would be greatly appreciated.
