With the HydrographicS57Layer, is it possible to extract the sounding/depth at the point the user clicks? I have managed to get the DRVAL1 and DRVAL2 from the cell which I assume is the upper/lower depth in the area, but how do I get the actual depth (the number displayed on the map)?
Also, I am wondering what is the best-practice for loading a potentially large number of S57 cells onto the map at once with decent performance? Is it possible to load/show layers based on the S57 scale band, visible extent or similar?
We are currently evaluation the ArcGIS Runtime SDK for our upcoming WPF marine application, and how well it supports S57 will largely influence our decision.
