Things that stood out to me from memory&amp;#x2F; links and stuff&amp;#x2F; some of my own thoughts:&lt;p&gt;- OSM does not always show some data. This does not really matter because the vector data is all available, and the openstreetmaps.org basemap is just one rendering of many. A good example of this is mapbox, which is one of the most beautiful basemaps out there.&lt;p&gt;- If you see something wrong, you can just hit the edit button and use the web editor (Id), which is super easy and contains more metadata than any other map app in this category. For example, I used this yesterday to find the type of pavement on a bike route near my house.&lt;p&gt;- Google spends 1 billion + per year on maps. This is likely primarily a) streets and b) data&amp;#x2F;company aquisitions which may not meet quite the same standards as OSM. The fact that OSM editors are obsessed with detail in their local area probably explains a lot.&lt;p&gt;- A map of the world should be something we all own. No company should have a monopoly on how we perceive the world around us, but companies should still be able to commercialize this stuff (like mapbox and others are doing).&lt;p&gt;- One point of contention that came up in the discussion was whether or not OSS can really compete with commercial solutions when there is so much money involved. Counter points to this are that mapping the whole world is something that requires a large networking effect and is not efficient for a company to do.&lt;p&gt;- GIS is one industry that has been seriously plagued by corporate wrangling. From the servers to the analysis apps to the geoprocessing engines to the underlying data; much of the innovation is hindered by companies locking down what they have (often with governmental tacit support, which exacerbates the problem quite a bit).&lt;p&gt;- There are many efforts to combat the monopoly-holder&amp;#x27;s&amp;#x2F;government&amp;#x27;s iron grip on this information and processing ability. Among these efforts that are hot on my radar include:&lt;p&gt;- QGIS: an open source gis desktop application that just saw amazing improvements with a 2.0.&lt;p&gt;&lt;a href=&quot;http://www.qgis.org/en/site/&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.qgis.org&amp;#x2F;en&amp;#x2F;site&amp;#x2F;&lt;/a&gt;&lt;p&gt;- TileMill: an application that allows you to create custom basemaps. This was previously a process that required a expensive software and collection of phds.&lt;p&gt;&lt;a href=&quot;https://www.mapbox.com/tilemill/&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.mapbox.com&amp;#x2F;tilemill&amp;#x2F;&lt;/a&gt;&lt;p&gt;- OSM: open map data that allows for almost infinite possibilities, since it lets you easily correct an error or download data and render it however you want.&lt;p&gt;&lt;a href=&quot;http://www.openstreetmap.org/#map=5/51.500/-0.100&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.openstreetmap.org&amp;#x2F;#map=5&amp;#x2F;51.500&amp;#x2F;-0.100&lt;/a&gt;&lt;p&gt;- mapschool: A cool intro to GIS which has the potential to displace a lot of the overcomplicated training programs that have an inherent bias towards particular proprietary tools.&lt;p&gt;&lt;a href=&quot;http://macwright.org/mapschool/&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;macwright.org&amp;#x2F;mapschool&amp;#x2F;&lt;/a&gt;&lt;p&gt;- Leaflet: a js library for client side map rendering. It is without a doubt easier to use than any of the alternatives, and tends to handle mobile better to boot.&lt;p&gt;&lt;a href=&quot;http://leafletjs.com/&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;leafletjs.com&amp;#x2F;&lt;/a&gt;&lt;p&gt;- d3: A slick data visualization js lib sort of like jquery for data that can create mind blowing charts and maps.&lt;p&gt;&lt;a href=&quot;http://d3js.org/&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;d3js.org&amp;#x2F;&lt;/a&gt;&lt;p&gt;- turf: a node.js library I have been working on (yeah, shameless plug) that aims to create a server side or client side full featured geospatial processing&amp;#x2F;stats engine with an easy to use api. The inspiration was largely taken from GRASS and my main goal was beating the hell out of arcpy on performance (it is orders of magnitude faster on the metrics I cared about when writing it).&lt;p&gt;&lt;a href=&quot;http://morganherlocker.com/post/turf&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;morganherlocker.com&amp;#x2F;post&amp;#x2F;turf&lt;/a&gt;</text></comment>

I then use this to make print maps; part of my work with a local mountain biking advocacy non-profit. In fact, just yesterday while watching a storm blow outside my window I put this one together:&lt;p&gt;&lt;a href=&quot;http://mmba.org/library/maps/baldmountainnorth/latest.pdf&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;mmba.org&amp;#x2F;library&amp;#x2F;maps&amp;#x2F;baldmountainnorth&amp;#x2F;latest.pdf&lt;/a&gt;&lt;p&gt;I don&amp;#x27;t really contribute the data I collect to Google Maps because it&amp;#x27;s much more one-way... Sure, I get to use their mapping site, but I can&amp;#x27;t get the data back for making print maps.&lt;p&gt;If anyone is interested in the general process I follow for it, that can be found here:&lt;p&gt;&lt;a href=&quot;https://nuxx.net/blog/2012/06/05/mtb-trail-mapping-workflow-with-openstreetmaps/&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;nuxx.net&amp;#x2F;blog&amp;#x2F;2012&amp;#x2F;06&amp;#x2F;05&amp;#x2F;mtb-trail-mapping-workflow-...&lt;/a&gt;</text></comment>
