<title>Diffable, more customizable maps</title>
<base href="https://github.com/blog.atom">
<p>We're excited to announce two improvements to mapping on GitHub
today: diffs and feature-level customizations.</p>
<h2>Visualizing changes over time</h2>
<p>We added <a moz-do-not-send="true"
href="https://github.com/blog/1528-there-s-a-map-for-that">the
ability to visualize geospatial data</a> to GitHub last
summer, but the true value of version control comes not from
where your information is now, but how it's changed over time,
and where others propose it should be.</p>
<p>Starting today, any time you view a commit or pull request on
GitHub that includes geodata, we'll render a visual
representation of what was changed. For example, here's <a
moz-do-not-send="true"
href="https://github.com/benbalter/congressional-districts/commit/2233c76ca5bb059582d796f053775d8859198ec5">a
diff</a> of Illinois's famed 4th congressional district after
undergoing redistricting in 2011:</p>
<p><a moz-do-not-send="true"
href="https://github.com/benbalter/congressional-districts/commit/2233c76ca5bb059582d796f053775d8859198ec5#diff-85d2c1b78193e963475250414e57940b"><img
moz-do-not-send="true"
src="https://f.cloud.github.com/assets/282759/2090660/63f2e45a-8e97-11e3-9d8b-d4c8078b004e.gif"
alt="Illinois 4th Congressional district"
style="max-width:100%;"></a></p>
<p>We'll even diff properties within the geometry when they
change:</p>
<p><a moz-do-not-send="true"
href="https://github.com/DU-GIS/Geojson_Data/commit/042e86e417a7fb9e43504640046339e82618e4c2#diff-0cca6b7c0e294c8d3e9d9b8090ab9e24"><img
moz-do-not-send="true"
src="https://f.cloud.github.com/assets/282759/2022569/dfaf96b8-884f-11e3-95ca-8f54c60a2ccf.png"
alt="Updating a property" style="max-width:100%;"></a></p>
<h2>Customizable maps</h2>
<p>We've also made some changes under the hood to make <a
moz-do-not-send="true"
href="https://help.github.com/articles/mapping-geojson-files-on-github">mapping
geoJSON files on GitHub</a> faster and more customizable.</p>
<p>In addition to more-responsive, retina-ready maps, you can now
customize individual features by specifying properties such as
the fill color or opacity within the geoJSON file itself like <a
moz-do-not-send="true"
href="https://github.com/nationalparkservice">the National
Park Service</a> did here:</p>
<p><a moz-do-not-send="true"
href="https://github.com/nationalparkservice/npmap.js/blob/master/examples/data/simplestyle.geojson"><img
moz-do-not-send="true"
src="https://f.cloud.github.com/assets/282759/2022677/2316367c-8851-11e3-8ecb-580ac8f85284.png"
alt="simple style spec" style="max-width:100%;"></a></p>
<p>We've implemented <a moz-do-not-send="true"
href="https://github.com/mapbox/simplestyle-spec/tree/master/1.1.0">version
1.1.0 of the open simplestyle specification</a>, so be sure to
check out <a moz-do-not-send="true"
href="https://help.github.com/articles/mapping-geojson-files-on-github#styling-markers">the
full documentation</a> for the details.</p>
<p>Happy collaborative mapping!</p>
