Or you could just use the centrelines. These are not quite so rigorously defined as axial lines but for most purposes will be adequate.

Hi Daniel (and Zeina). 
Thank you so much for your reply! 

That is indeed correct - I did an offset from center lines of streets and paths. That is the base map that I got. 
BTW - (roads and streets’ ) center lines are available to download for whole Norway here, for those of you who might be interested in it. 

So I think I have two options:  draw the axial lines myself (if i get a better base map) or try Axwoman to generate them from the center lines. Iim going to try to do both. 

Thanks again for your support with this! 
It is so great to have an online community that  is there to help! 

Best greetings,

Dear Aga,

 after a brief look at your dxf it seems you have extracted the outlines of paths and streets, is this correct? If this was pre-existing this may make sense, otherwise I would advocate drawing the axial lines manually, as this also allows you to take for instance elevation changes into account (I suspect there are such in Norway but I suppose it’s not so everywhere). Depending on the morphology you work in, first extracting paths and then drawing axial lines on them is not self-evidently the best procedure.

However, I believe the automatically generated maps in Depthmap is better suited for situations where you rather have blocks as defining elements to generate from rather than narrow paths. AFAIK the reason for this is related to the theory behind axial maps. 

Looking at the size of the town, I think it is within the size where I would advocate making the axial map manually, taking better into account the full material morphology and not just street outlines. The alternative to that would to me be to use road-centre lines to generate a segment map, but for the size of town you work with manual seems the best. 

Importantly, if you wish to work with axial maps the conceptual ground needs to be clear; the exact location of a line matters only so far as deviations misrepresents the material morphology, and the method you chose to proceed is tied to the question which you are seeking to answer.

Best
Daniel

Hi all, 

I am trying to run axial analysis on a dxf map of a small town in Norway. 
The file represents all walkable paths


When I get depth map to draw axial lines it doesn’t ‘fit them in’ the lines in some of the paths. 
Is there some way around it? Can for example the axial lines be made thinner to fit in in the paths?
Should I try to make the paths even wider (as of now they are 4 m wide, and I would be risking that they would start overlapping)

I would greatly appreciate any thoughts and suggestions! 
Thank you in advance! 

Best,
