Visualizing AIS Fishing Activity with Datashader and Cesium

In this talk, I will discuss the second iteration of the Fisheries Observation Tools application, developed by The Institute for Big Data Analytics, which combines the Datashader and Cesium libraries to visualize fishing vessel activity on a 3D globe. Datashader  ( is an open source Python library developed by Continuum Analytics that generates 2D heat maps for very
large datasets for use with the Bokeh plotting library. Cesium  ( is a JavaScript library developed by The Cesium  Consortium that uses WebGL to apply map tiles and imagery to a globe.

This presentation will describe how Datashader image data is used to produce heat map imagery in Cesium and how Cesium's animation system is
used to display and filter vessel movement using Automatic Identification System (AIS) data indexed in Solr.
