<p><span style="font-size: 12pt;">Dear (Geo-)Visualization Community,</span><br>
</p>
<p><br>
We would like to invite you to participate in the VGI Geovisual Analytics Workshop associated with the 4th International Symposium on Big Data Visual and Immersive Analytics, (October 17-19, 2018, Konstanz, Germany). </p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">We are pleased to announce that Prof.Jo Wood (https://www.gicentre.net/jwo/index/) will be our keynote speaker! </span></p>
<p><br>
</p>
<p>We are calling for abstracts submissions ~2500 characters (ca. 300 words) consisting on a brief description of ongoing research plus 1 or 2 visual illustrations (e.g. figure, etc.). The submission should be in PDF format. Authors with accepted abstracts
will be invited for a presentation in the workshop. <span style="font-size: 12pt;">The Geovisual Analytics Workshop will bring together researchers from visualisation and geoscience community to investigate how the general concepts of Visual Analytics can
be used for the spatio-temporal analysis and interpretation of Volunteered Geographic Information (VGI) research.</span></p>
<p><br>
</p>
<p>Special notes for IEEE VIS participation. <br>
</p>
<p>Directly from Zurich Airport (ZRH) there are a number of convenient train connections to Konstanz Train Station which take around 1 to 1.5 h. <span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);">It
