Hello,
i'm testing uDIG to use it as a base GIS application for my company. I would like to load 50000-500000 point features from a postgis database. The uDIG table view can't handle so many features and the map rendering is slow. When working with OpenJUMP and gvSIG i don't have these problems. Especially the table is working with no problems (using JTable, Swing).
- Why do these problems occur in uDIG? (using swt table? using swt rendering?)
- How can these problems be fixed?
- What would you guess how much effort would it be to fix it?
Best Regards
Carsten
Hi Carsten,
The Table View has known issues which we hope to tackle soon. Any
rendering slowdown should merely be a side effect of these problems. I
believe the main issue with the table view is that it does not load its
contents lazily, and therefore performance decreases with size.
I assure you that when the table view is up to our QA standards, it will
not have these problems. Unfortunately I do not know the exact nature
of the problem (others will have to comment), nor the effort required to
fix. However, the problem stems from our current implementation
(incomplete), not the technologies backing it.
Cory.
