I'm currently developing an ArcGIS based flex web viewer. ArcGIS is great for most of the things but there are some issues like performance and license costs.
That's why I'm looking into possible alternatives. At the moment I've found 3 possible alternatives, but I'm not sure what they are capable of, so I'm wondering if some people on here have more experience with them.
I have been reading the docs and will try to experiment with some of these, but it will take a lot of time to find out all these requirements. So it would be of great help if you could point me in the direction of software I should try out.
These are our requirements:
- easy scalability
- advanced labeling (different label colors based on attributes, labels placed in a rectangle)
- render cached data
- network tracing possibilities (for sewers, so trace upstream and downstream)
- printing (generating pdf's)
nice to have:
- easy to start with
