This sample demonstrates how you can display geospatial data onto a map using the HTTPTupleView operator, and OpenLayer APIs.

This application has two custom operators that randomly generates geospatial locations of two types of entities around Hong Kong:

• Taxi entities are represented by red markers on the map.

• Public minivan entities are represented by green markers on the map

To see this sample in action, compile and submit the main application to a streams instance.

To compile the application, you need:

• Streams 4.0 - for the new com.ibm.streams.geospatial toolkit

• com.ibm.streamsx.inet toolkit v2.5 prerelease from here: https://github.com/IBMStreams/streamsx.inet/releases
