Map viewer is a kool technology and I wanted to write
about it for a long time.
Let me first chalk the steps that we will follow. We will
1. Download Map Viewer and Map Builder.
2. Create a pluggable database (pdb), create a pdb user and grant the necessary privileges to it.
3. Configure Map viewer.
4. Insert spatial data.
5. Use Map Builder to create styles and themes.
6. Get a key from google and then use it to create a map tile layer using Map Viewer.
7. Write code to create a FOI layer on a base map using Map Viewer's JavaScript API.
