Hello CartoTalk forum members, I'm totally new on this board, I'm not a massive gis user, though I have happened to be using cartographic software for simplifying maps for some traffic simulation software. Now, for pure testing purposes I find myself in need of a very simple polyline shp file; what I need to build is a simple map of 10 polylines intersecting 10 more polylines at regular 200m intervals, forming a sort of a 10x10 square grid, each polyline having 200m extra on both sides, with nodes at each intersection. I suppose there must be some effortless way of doing somethiing this simple, but my ignorance on geographic software is making it more challenging then I suppose it really is. Can you help me? Thank you very much.

What tools do you have handy? Or are you looking at setting up (buying) some software?

Are you comfortable with plotting points in ArcMap, and then perhaps with creating features in an edit session? If so, you could plot all your desired points from a table you make up in a spreadsheet using coordinates, and then draw lines, probably using "snapping," to connect your points. That would give you a perfect matrix like what you described.

Ah, sorry, didn't notice the QGIS in the rest of the subject line. I imagine you could probably still do something along the lines of my previous suggestion - I just don't know what those procedures would be called in QGIS, since I've only used it a little.
