Dear community,
I have a KML layer that shows PNG graphic as a Map overlay. It's shown in a left bottom corner of a Map.
It is controlled by a KML layer: if layer is off - it's too. I tried to find it with CIMViewer, and attributes search in Visual Studio.
KML file is from USGS (link). I opened it as a text file and found a block that specifies the png file:
<ScreenOverlay>
<name>Legend</name>
<visibility>1</visibility>
<Icon> <href>http://mrdata.usgs.gov/sedexmvt/legend.png</href></Icon>
<overlayXY x="0" y="0" xunits="fraction" yunits="fraction"/>
<screenXY x="0" y="0.02" xunits="fraction" yunits="fraction"/>
<rotationXY x="0" y="0" xunits="fraction" yunits="fraction"/>
<size x="0" y="0" xunits="fraction" yunits="fraction"/>
</ScreenOverlay>
Please, could you help me to understand how it works. I wonder if I could switch off that overlay, and if I could set my own similar overlay for another layer?
