Polyline to polygon to split polygon?

[goran.klensmeden]

I have a rather complex net of roads and parking lots in the shape of a hatched polyline (basically a whole city). I now want to create a polygon from this net, which I later on want to be able to edit and split into a number of polygons.

Anyone with experience from that sort of operations?

My humble advice: _MAPEXPORT the N layers (linear, polygon, and so on) to N shapefiles, then perform that kind of boolean operations in the opensource Qgis, sir.

Thank you!

I´ve been leaning towards that solution, but I really wanted to be able to solve it without exporting/importing. We´ll see how that works out! 🙂

Hi,

>> I now want to create a polygon from this net,

I even don't understand the job.

As I understand you have a line-theme describing streets, from that you want to create a polygonal theme? That returns the area between the street-lines (if the area is closed) .... does that make sense? Is that what you plan to do or what am I missing?

@ALfred: Exactly! MAybe I expressed it alittle bit blurry, though. At the moment Í´m working with a different way of solving it by exporting the dwg to TAB and then use MapInfo. Works fine so far.
