Hi. I’m *very* new to SharpMap. Does anyone have any ballpark figures for SharpMap v2’s ability to render and use very large maps – for instance a street-level vector map of the UK? In a typical format, this could be around 0.5 GB.
With different zoom levels you’d have different types/levels of features visible – i.e. only motorways would be visible when you’re zoomed really far out, etc. Thus you wouldn’t expect to have more than perhaps 1000 objects on-screen
at any one time (although for long roads you’d expect a single road object to be made up of hundreds or thousands of individual line segments). To complicate matters your approx. 1000 on-screen objects would be sampled from database/dataset containing
millions of objects.
Can SharpMap cope with this amount of data and how long would it typically take to render something like this? In the ideal scenario rendering speeds would need to be something like 1/10<sup>th</sup> of a second…
Thanks very much
