		<description><![CDATA[In an article &#8220;Why Geo]]></description>
			<content:encoded><![CDATA[<p>In an article &#8220;<a href="http://www.directionsmag.com/article.php?article_id=3413">Why Geo Will Embrace The Cloud in 2010</a>&#8221; in <a href="http://www.directionsmag.com">Direction Magazine</a>, <span class="normal"><a title="More about this author" href="http://www.directionsmag.com/author.php?author_id=634">Brian Timoney</a></span> of the <span class="normal"><a title="More about this company" href="http://thetimoneygroup.com/" target="_new">The Timoney Group</a> looks at the emerging cloud computing arena and poises the question, fad or not? Putting that question aside for the moment, part of Brian&#8217;s article really struck a chord with me – &#8220;IT is suffocating GIS.&#8221; As a former statewide GIS coordinator, I&#8217;ve seen all too many enthusiastic GIS professionals sucked down this path. Brian articulates something rarely discussed – issues like burn-out in the long since changed role of GIS managers. Are we properly preparing GIS professionals for this aspect of their GIS career? Here is an excerpt of Brian&#8217;s article:<span id="more-673"></span><br />
</span></p>
<p><span class="normal">&#8220;Ask average, ordinary stressed-out GIS managers about their day and the likely response will be a litany of grievances about servers, networks, licenses and unhappy users of Web applications. Note that most of the above have little to do with the traditional responsibilities of GIS departments such as maintaining positional accuracy of spatial data, spatial analysis and cartographic production. Instead, much energy is devoted to maintaining the complex choreography of connectivity between desktop applications, databases, servers and Web portals. With budgetary pressures showing little sign of abating, shops are forced to make difficult trade offs in managing their mix of IT and personnel expenses.  The costs of this complexity are significant in ways that are both explicitly financial but also somewhat psychological, as industry veterans lose their enthusiasm under the burden of IT management responsibilities that hold little intrinsic interest.&#8221;</span></p>
<p><span class="normal">While Brian suggests that cloud computing might offer a solution to this and other ills, I&#8217;m not so sure. The cloud is certainly already playing a positive role in the geospatial technology field, and indeed might ease GIS/IT administrative pressures.<span class="normal"> However, security concerns such as </span><span class="normal"><a href="http://www.wired.com/threatlevel/2010/01/operation-aurora/">Google hacks from China</a>, its own technology management needs, and even internal data access policies are likely to be major obstacles for enterprise operations to embrace the cloud (and have it replace existing operations). Nonetheless, identifying the problems is a big part of defining the solution. Cloud computing or not, I applaud Brian for succinctly putting his finger on this button. More exploration may reveal: Why are we here today? What is the source of these problems? What are other potential solutions?</span></span></p>
<p><span class="normal"><span class="normal">With more open dialog like this we might all breath better.</span></span></p>

		<description><![CDATA[I&#8217;ve been very interested in]]></description>
			<content:encoded><![CDATA[<p>I&#8217;ve been very interested in the news stories I&#8217;ve read about neighborhood boundary data and its usefulness.  About a year ago Adena Schutzberg, Directions Magazine, <a href="http://www.directionsmag.com/article.php?article_id=2686&#038;trv=1">wrote about neighborhood data</a> offereings and the announcement by <a href="http://www.zillow.com/webtools/labs/neighborhood-boundaries.htm">Zillow.com</a> that they would provide their neighborhood GIS shapefile data freely through a <a href="http://creativecommons.org/licenses/by-sa/3.0">Creative Commons license</a>.  First of all, I am very interested to see the CC licensing being applied to geospatial data &#8211; this alone is worth following.  And I applaud Zillow.com (which I love) for making their data available in this way.  So I was really interested when I came across another very excellent site providing my home&#8217;s walkability score (which alas is moderately low) and my office (which is very highly walkable).</p>
<p><div id="attachment_397" class="wp-caption aligncenter" style="width: 310px"><a href="http://drjill.net/wp-content/uploads/2009/03/picture-2.png" rel="attachment wp-att-397"><img src="http://drjill.net/wp-content/uploads/2009/03/picture-2-300x250.png" alt="walkscore.com" title="picture-2" width="300" height="250" class="size-medium wp-image-397" /></a><p class="wp-caption-text">walkscore.com</p></div><br />
<a href="http://www.walkscore.com/">Walkscore.com</a> is a site worth visiting.  &#8220;Walk Score helps people find walkable places to live. Walk Score calculates the walkability of an address by locating nearby stores, restaurants, schools, parks, etc. Walk Score measures how easy it is to live a car-lite lifestyle—not how pretty the area is for walking.&#8221; The Walk Score algorithm awards points based on distances to the closest amenity in a number of categories.  I especially love the heat maps showing the <a href="http://www.walkscore.com/rankings/most-walkable-cities.php">most walkable neighborhoods in the top 40 U.S. cities</a>.  And certainly turn around is fair play&#8230; Zillow is already leveraging the benefits of having made its neighborhood data available (in February, Zillow.com added WalkScore to each of their 87 million properties).</p>

			<content:encoded><![CDATA[<p>As mapping professionals, we often want more detail &#8211; the more accurate the better. But occasionally we need to simplify our maps (specifically our shapefiles) for presentation purposes or to speed up web map applications. Now you can very easily simplify your shapefiles online using <a href="http://www.mapshaper.org/">MapShaper</a>. I&#8217;ve used it and it was a breeze. Here is some info directly from their blog: &#8220;MapShaper is a free online editor for Polygon and Polyline Shapefiles. It has a Flash interface that runs in an ordinary web browser. Mapshaper supports three line simplification algorithms: Douglas-Peucker, Visvalingam-Whyatt, and a custom algorithm designed to smooth convoluted coastlines and spiky features.  The MapShaper project was conceived in 2005 by <a href="http://maps.grammata.com/">Matthew Bloch</a> and <a href="http://www.geography.wisc.edu/~harrower/">Mark Harrower</a> at the University of Wisconsin, Madison Geography Department. <a href="http://maps.grammata.com/autocarto2006_paper.pdf">A paper [pdf]</a> from the 2006 AutoCarto conference describes how MapShaper works “under the hood.”&#8221; Since it is a web application, you upload your shapefile, tell it what simplification program to run, and let it go. Thanks Matthew and Mark for a very nice app.</p>
