comment Draw lines between two points in QGIS
So where you've got x1 and a1 and a2 you've got actual numbers in your spreadsheet? And the X coordinate is the same for from and to? So the lines are vertical? Not clear.

comment Lat Long to Useable values in QGIS
How have you been given these locations? In a spreadsheet, text file, written on a scrap of paper? Any chance we could have a sample of the source?

comment Writing shapefile with projection defined crashes fiona
Works fine for me on Linux (at least to epsg:4326), so you aren't doing something crazy. Can you narrow it down to the opening or the writing, or the closing (which happens when the 'with' context handler ends). Try it with a plain c=fiona.open(....) call then see if that's crashing or the c.write...

@RyanDalton this has a bit more GISsy functionality in it though. That question is just a static map.

comment How to shrink polygon on two sides?
There's another complication. Are these in lat-long? Are they "large"? Are they rectangles in lat-long, and hence not really rectangles? Hmmm
