Once you have added the Google Maps Layer, you will be prompted to
enter an API Key. Please read the note in the previous section. For local
use you do not need an API key, simply type any character into the API
Key field.
Select from the ‘Map Type’ drop down list the Google Maps layer you wish
to see by default when you open your report or toggle on the background
layer. The end-user will be able to change the Google Maps layer they see
through a drop down list in the map (Figure 163).

The Publisher will automatically re-project all base and contextual layers
you have uploaded for your report into the geographic coordinate system
‘WGS 1984 Web Mercator (Auxiliary Sphere)’ to match the Google Maps
projection.
It is vital that you consider the following points:
This re-projection only works if the Publisher knows the coordinate
system of your map files. If you are using ESRI shapefiles that
include a .prj file, the Publisher can pick up the coordinate system
information out of this file. If your shapefile does not have a .prj file
or if you are working with MapInfo MID/MIF or TAB files, you will
need to select the appropriate coordinate system from the Layer
Properties in the ‘Coord System’ tab. Alternatively you can re-
project these map layers before using them in InstantAtlas.
