Here is my working example:
https://github.com/mores/maven-examples/blob/master/gis/src/test/java/org/test/MapTest.java
The test will add a random set of points near 3 cities. I can output the
counties and points to out.jpg <- works
I am able to save the RenderedImage of HeatmapProcess to heat.tif <- works
But when I try to add the heatmap layer to MapContent I get:
java.lang.NullPointerException: Unable to transform referenced envelope,
crs has not yet been provided.

Any help is appreciated.
