Hi all,
here I am again. I need to retrieve information about a layer in a
MapContext based on a point (x, y). I saw that there are VectorLayerHelper
and GridLayerHelper, but I'm not having success. I'm trying as follows:
VectorLayerHelper helper = new VectorLayerHelper(map, map.getLayer(0));
if (helper != null && helper.isValid()) {
DirectPosition2D queryLocation = new
DirectPosition2D(map.getCoordinateReferenceSystem(),300, 250);
coll = helper.getInfo(queryLocation);
FeatureIterator it = coll.features();
}
The code returns an empty iterator, even if there is a feature in that
point. Does anyone have any tips or know another way to do this?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
