<div><p>Look at a dataset (try <a href="https://github.com/wboykinm/vcgi-demo1/blob/master/morristown_corners.geojson">this example</a>)</p>
</div>
<div><p>To add new data, convert from your fave format first. tools:</p>

</div>
<div><p>A few options:</p>
</div>
<div><p>Tiny data (&lt;8MB): Use <a href="https://geojson.io">geojson.io</a></p>
</div>
<div><p>Bigger data (8MB - 100MB): Edit locally and sync using the github app</p>
</div>
<div><p>Big data (&gt;100MB): We&#39;re not really there yet. </p>

</div>
<div><p>github pages - web apps, hosted for free</p>
</div>
<div><p>That repository you forked comes with a <a href="https://github.com/wboykinm/vcgi-demo1">simple viewing app</a></p>
</div>
<div><p>updates to data are immediately available in the app </p>
</div>
<div><p>(this can get a lot more complicated, but it doesn&#39;t need to)</p>
</div>
<div><p>What&#39;s missing?</p>
</div>
<div><p>Geoprocessing (though we&#39;re <a href="https://turfjs.org/examples/turf-count/">getting there</a>)</p>
</div>
<div><p>Scale - this one <a href="https://ben.balter.com/2013/11/21/thats-not-how-the-internet-works/">might require a paradigm shift</a></p>
