Hi,
I want to automatically zoom into areas of interest on my map, but only to
the level where I have either ASRP or CADRG showing.
However, I can't work out how to get the minimum scale from the layers...
I use the following code to discover the minimum scale that will result in
CADRG showing at that point:
float minScale = Float.MAX_VALUE;
Layer[] layers = layerHandler.getMapLayers();
for (int i = 0; i < layers.length; i++) {
if (layers[i] instanceof RpfLayer) {
float minRPFScale =
layers[i].getProjection().getMinScale();
minScale = Math.min(minScale, minRPFScale);
System.out.println(layers[i].getName() + " minScale
= "+minScale);
}
}
My CADRG prints that its minimum scale is 500.0, however, on the map it does
not show at all until 1:125K. Using the CADRG coverage tool, it reports
that at this point I have TPC (1:500K) and ONC (1:1M) , I also have other
data that shows at higher scales, which is not reported by the coverage
tool.
Does anyone have any ideas what's going on? Does the 500.0 representing
500,000? If so, is the scale always factored by one thousand? Or is there
another way to discover the minimum showing scale...?
Thanks!
Laura
