Thank for information. Could you please tell me in what format you write to system file, and then in which - to gdb?

comment ArcGIS 10 - disappearing rasters?
@jan_b Thanks for information. Quite unusual behaviour for such an expensive piece of software I'd say :/ I tried recalculating pyramids and statistics - to no avail. May I ask to which format you converted as a remedy?

comment What are good colour schemes for large density flow maps?
As much as I love and use CB tool - it's hard to apply it here since I do not need sequential, diverging nor qualitative schemes. Rather - one colour to represent flows and good contrasting background colours.

comment What are good colour schemes for large density flow maps?
Thanks @WhiteboxDev Using colour ramp might not be that easy. I'm basically mapping all individual lines with the same hue. It's the transparency and overlay of the lines that gives them intensity of the colour.
