<h3>Goals of the Contest</h3>
<p>As a reminder, the goal of the contest was to “do something in R, with a shapefile, that does something other than make a choropleth map”. This goal was entirely selfish: I have spent years analyzing data using choropleth maps. But as I don’t have a background in geospatial statistics, I am really not aware of what other analytical techniques I can be using. I hoped that by running a contest I could learn some more useful techniques that I could then apply to my own work.</p>
<h3>And the winner is …</h3>
<p>There are actually two winners to the contest. They both provided concise explanations, and real-world demonstrations, of geospatial concepts that I was simply not aware of.</p>
<ul>
<li><a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cDovL3BlcnNvbmFsLnRjdS5lZHUva3lsZXdhbGtlci9zcGF0aWFsLW5laWdoYm9ycy1pbi1yLmh0bWw%3D&feed-stats-url-post-id=3199">Spatial neighbors in R – an interactive illustration</a> by Kyle Walker. Kyle is a geography professor. This might have allowed him to intuitively understand the types of analyses that I was looking for. His entry demonstrates different definitions of “neighbor” in spatial statistics, and how those definitions can effect interpretations of the data.</li>
<li><span><a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cHM6Ly9wcmFjYWRlbWljLnNoaW55YXBwcy5pby9MSVNBLw%3D%3D&feed-stats-url-post-id=3199">London Crime Analysis</a> by Henry Partridge goes a step further. Henry developed an application to map different types of crime in London. He then used <a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvTW9yYW4lMjdzX0k%3D&feed-stats-url-post-id=3199">Moran’s I</a> to calculate spatial autocorrelation. There were actually several entries that deal with mapping crime, but only Henry’s entry introduced this extra step beyond a choropleth maps.</span></li>
</ul>
<p>It’s worth pointing out that both of the winning entries used RStudio’s <a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cDovL3NoaW55LnJzdHVkaW8uY29tLw%3D%3D&feed-stats-url-post-id=3199">Shiny</a> framework.</p>
<h3>Honorable Mention</h3>
<p>Several entries besides the winners stood out as teaching me something new in the area of R and shapefiles in a concise, enjoyable way:</p>
<ul>
<li><span><a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cHM6Ly9naXRodWIuY29tL2Z1bmd5aXAvc3BhdGlhbF9hbmFseXNpc19pbl9y&feed-stats-url-post-id=3199">Hong Kong Population Center of Gravity (COG)</a> by Fung Yip taught me about the concept of a <a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvQ2VudGVyX29mX3BvcHVsYXRpb24%3D&feed-stats-url-post-id=3199">Center of Population</a>.</span></li>
<li>In <a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cDovL3JwdWJzLmNvbS91dGVuZ3IvMTk4ODM1&feed-stats-url-post-id=3199">Working with Shapefiles</a> Dennis Chandler used shapefiles to explore US historical boundaries, from 1629 to 2000. I did not know that such data existed!</li>
<li>In <a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cHM6Ly9naXRodWIuY29tL0JyZXphL0RDX3BhcmtpbmdfdmlvbGF0aW9ucw%3D%3D&feed-stats-url-post-id=3199">Washington, DC Parking Violations</a> <span>Andrew Breza contrasts several different visualization techniques for analyzing parking violation data in Washington, DC. Before reading this I would have used just a choropleth to visualize the data. I learned a lot of new techniques from this!</span></li>
<li>In <span><a target="_blank" href="http://www.arilamstein.com/?feed-stats-url=aHR0cDovL3JwdWJzLmNvbS9kYW5pZWxlcXVzLzE5OTE1MA%3D%3D&feed-stats-url-post-id=3199">Marine Boundaries in R: Reading EEZ Shapefiles</a> </span>Daniel M. Palacios give a thorough treatment of a real-world issue involving geography, marine data and national borders. He is clearly an expert in this field, and I enjoyed learning about his speciality.</li>
</ul>
<h3>Prizes</h3>
<p>As a reminder, both of the winners will get two prizes:</p>
