osgEarth with schools and air polluters

Enable OsgEarth and CalSchoolFit in vroom.xml:

<OsgEarth value="off" />
<BorderWait value="off" />
<CalSchoolFit value="off" />

You need to adjust <Hand1> in the configuration. Comment block the first definition (this is the green arrow Andrew uses), and uncomment the second block.

          <Address system="1" body="0" />
          <ButtonMask system1="0x0F" />
          <Valuator0 system="1" number="0" />
          <Address system="4" body="0" />
          <Graphic value="CONE" />
          <ButtonMask system3="0x0F" />
          <GenPositionEvents value="false" />

To fly, in the menu select OsgEarth and enable navigation mode and then select fly as your default navigation means.

OsgEarth has simple schools you can enable and disable and smog blooms. CalSchoolFit has the stacked bar graphs that you can enable and disable for the different grads.
