Hi,
According to the Oracle Blog 'Options for Visualizing Spatial Data in Oracle' the latest version of the Map Builder tool is 20c, which enables Oracle Autonomous Database wallet connections as wish to set up the Mapviewer mvdemo demonstration to go through the tutorials.
I cannot locate where to download this version as the 'Spatial Map Visualization Component Downloads' page only appears to provide version 19.1.0?
Any advice please? Many thanks.
