Line overlapping point Mapsuite Winforms 10

Continuing the discussion from Layer order and LayerOverlay speed:

Hi Carlos,

Although it looks like the issue Craig encountered, but it is a whole different situation.
Lines and points in the same InMemoryFeatureLayer do tend to overlap each other; it’s caused by some historical reasons.
We still haven’t decided if we’ll fix it or not, we’ll let you know when we do.

Before the fix that may or may not come out, we have some workaround for you:
1. Avoid setting inner color and center color for line styles. The outer color of line won’t cover up any points.
2. Use different InMemoryFeatureLayers for points and lines, this way, the lines won’t cover up the points and we have no limitation on using styles.

We are sorry for any inconvenience this may have caused, and we’ll let you know if we’ll fix it.

Regards,
Tsui

I’m facing same issue. Workaround 2 looks like an option but I need to refresh/ update these features every 100 ms (500ms Worst case). What would be performance penalty if I use 2 layers AutoRefreshing @ 100ms instead of one layer? Would that be fine?
Already I’m facing map refresh issues while zooming and panning at higher zoom levels (>15) even with tilecache in this scenario.

Earlier I’d used ArcGIS SDK for WPF 10.2 for Similar Application and never faced such issues. BTW I wish to migrate to Mapsuite 10 as ESRI has change SDK way too much with current version.

Hi Avinash,

I read your scenario, I think there is no difference when you using two layers auto refreshing.

For the zooming/panning performance issue, I have mentioned in another post.

And I recommend that you can consider to use WPF edition for your project. it will be more effective when panning or zooming.

If you meet any problem when migrating MapSuite 10.0, please contact us, we will help you to resole that.

Thanks
Mark
