I am conducting the study regarding to space syntax analysis. And as you know to do that, I need an axial map.

Actually I know the notion of axial map, and how to draw it in theoretically. As I know, I have to get an road outline map so that I can make an axial map, like the upper one that I uploaded. But in this country I found that I can get only this weird format just like the below.

I can't make all-line map and fewest-line map because these node poligons disrupt generating axial line. I mean when I press button that creates a all-line map, it only generates line between a node and a node.

I queried to the GIS platform website if there is an outline map that all roads are connected without that freaky node poligons, but they told me there's not. In this situation how the hell I can make an axial line map? The materials that teach how to draw an axial map only show a minimal space like a building and drawing it by hand in Autocad, not the large space that covers the certain region.

Of course I might draw the outline map on the AutoCAD, but the network that I want to analyze is an urban area that contains thousands of roads and I believe there might have been an easy way which I can perform it in software(like QGIS or depthmap). It won't be true that I have to draw all these by my hand.

Or do I have to use the road central line map? If so, please tell me what should I do with it?

Please help me. I'm gonna be crazy because of this...
