This is a significant moment in Mapnik’s history. With the recent update to the <a href="https://github.com/mapbox/vector-tile-spec">Mapbox Vector Tile Specification</a>, we are now creating tiles according to the updated spec. This version is built with the recently released <code class="highlighter-rouge">1.0.0</code> version of <a href="https://github.com/mapbox/mapnik-vector-tile">Mapnik Vector Tile</a> and against core Mapnik <code class="highlighter-rouge">3.0.10</code>, which was released last week.</p> <h2 id="download">Download</h2> <p>You can download the latest version from <a href="https://www.npmjs.com/package/mapnik">npm</a> or simply run <code class="highlighter-rouge">npm install mapnik</code>.</p> <h2 id="what-changed">What Changed</h2> <p>The updated Mapbox Vector Tile Specification is a major milestone for vector tile encoding. In general, the specification makes rules for generating vector tiles more explicit, with a focus on simple goemetry and implicit winding order to improve rendering speeds. For all the information on what changed in the API see the <a href="https://github.com/mapnik/node-mapnik/blob/master/CHANGELOG.md#350">v3.5.0 Changelog</a>.</p> <p>We have also updated our documentation surrounding Node Mapnik!

I realized suddenly that we don’t support a way for our cartographers to easily design maps that would be easy to view by a color blind individual. Determined to change this, I quickly dashed off to my development batcave!</p> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077377/fb015120-3af2-11e5-96e0-28bd98e350e6.png" alt="image" /></p> <p>After some quick research I found <a href="http://vision.psychol.cam.ac.uk/jdmollon/papers/colourmaps.pdf">a research paper on colour blindness</a>. After quickly deducing that color should be spelled with out a <code class="highlighter-rouge">u</code>, I proceeded to throw together an algorithm. (Artem thinks it spelled with a <code class="highlighter-rouge">u</code>)</p> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077401/68673de2-3af3-11e5-88b5-c26c92ca5fcd.png" alt="image" /></p> <p>I emerged from the bat cave with some new code in Mapnik. Image filters for three types of color blindness.</p> <ul> <li>Protanopia (1% of males) – filter: <code class="highlighter-rouge">color-blind-protanope</code></li> <li>Deuteranopia (1% of males) – filter: <code class="highlighter-rouge">color-blind-deuteranope</code></li> <li>Tritanopia (less than 1% of males and females) – filter: <code class="highlighter-rouge">color-blind-tritanope</code></li> </ul> <p>So here are some maps with the color blind filters!</p> <h2 id="original-wheat-paste">Original Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077535/f186b5e8-3af4-11e5-8fc7-de0dc84961d5.png" alt="image" /></p> <h2 id="protanopia-wheat-paste">Protanopia Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077535/f186b5e8-3af4-11e5-8fc7-de0dc84961d5.png" alt="image" /></p> <h2 id="deuteranopia-wheat-paste">Deuteranopia Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077535/f186b5e8-3af4-11e5-8fc7-de0dc84961d5.png" alt="image" /></p> <h2 id="tritanopia-wheat-paste">Tritanopia Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077535/f186b5e8-3af4-11e5-8fc7-de0dc84961d5.png" alt="image" /></p> <p>If all those maps look the same to you, you might be color blind.</p> <p><br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /></p> <p>Okay I lied, here are the real ones.</p> <h2 id="original-wheat-paste-1">Original Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9077535/f186b5e8-3af4-11e5-8fc7-de0dc84961d5.png" alt="image" /></p> <h2 id="protanopia-wheat-paste-1">Protanopia Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9089835/d5844212-3b5c-11e5-90ec-879756682b3f.png" alt="image" /></p> <h2 id="deuteranopia-wheat-paste-1">Deuteranopia Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9089855/ed32d180-3b5c-11e5-88ce-ceb3a1a18a0f.png" alt="image" /></p> <h2 id="tritanopia-wheat-paste-1">Tritanopia Wheat Paste</h2> <p><img src="https://cloud.githubusercontent.com/assets/1794907/9089861/f484cf7e-3b5c-11e5-95e6-e64f4530a747.png" alt="image" /></p> <p>These image filters are now released in mapnik <code class="highlighter-rouge">3.0.3</code> and node mapnik <code class="highlighter-rouge">3.4.3</code>!</p> Mapnik 3.0.3 Release 2015-08-12T00:00:00+00:00 http://mapnik.org/news/release-3.0.3 <p>Very pleased to announce 3.0.3 release!

As always the main focus is on stability, performance and addesssing issues which we discovered while testing.
