Chart detail not showing at various zoom levels #355

Hi Andreas,

We have the latest updated UK and Ireland charts via O-Charts.

It seems that there is an issue when zooming in or out from our home port. See images and what is shown at various zoom levels.

The second image is a useful zoom level but all of the poor information is now shown.

Is this a configuration issue or something we can affect by changing settings?

Cheers Tony

Not sure which problem is really the one... Try to increase overzoom/underzoom. Such gaps occur if the charts for a particular area differ a lot in their resolution.

Thats great. I set under zoom to 1 and overzoom to 8 and now have no gaps in the chart. I will experiment with settings to balance a good refresh rate with the details we see.

Thank you for the prompt response and the amazing software.

Cheers Tony
