		<description><![CDATA[The ESRI Community Basemap program&#8217;s new ArcGIS 10 template for Large-Scale Topographic Mapping is somewhat streamlined and cleaner when compared to its ArcGIS 9.3.1. predecessor.  But the template map document still has the ability to bring my workstation to its knees when doing stuff like printing.  I find myself unable to print 11&#215;17 or export [...]]]></description>

The &#8220;dsm40cm&#8221; model of Marin County has been published as the county&#8217;s default terrain on Google Earth. It&#8217;s a great pleasure to work with folks who are not troubled by a county representing its surface on a 40cm single-precision float grid that weighs in [...]]]></description>

		<description><![CDATA[There&#8217;s some progress on a couple of project fronts.  I&#8217;ve started assembling some USGS terrain for a 1:10 scale Level 1 build that could involve more OpenSim regions than I&#8217;ve ever stood up on one machine before.  Snapshot of progress is here, with a goal of 304 OpenSim regions for the model.  I expect that [...]]]></description>

		<description><![CDATA[Today I would like to share the inside production notes (it&#8217;s quite low tech for the most part) on making terrain sculpties. I have included a full region&#8217;s worth of working raw terrain, and a set of four megaprim sculpties that should help to clarify some of my mutterings in earlier posts. Stuff like precisely [...]]]></description>

		<description><![CDATA[The past four days have been a tremendous blur of internalizing NURBS into my mind, at least the SL sculptie variant of them. Now I&#8217;ve been aware for several months of how NASA used sculpted prims to represent detailed Mars craters (as published by Ireton), and I&#8217;ve certainly followed the beautiful work for David Rumsey [...]]]></description>
