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...

comment Building a WebGIS with search functionality for a charity
@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

Also, your "one third of the width" isn't too clear. Is the red section the same width as each of the blue sections?

Can you provide a sample shapefile/other file format with a few features in?

How do you decide which sides are the "sides" and which the "ends"? Is it always going to end up with a red section more vertical than horizontal?

comment Convert from eastings and northings to latitude and longitude without ArcGIS
Does the shapefile come with a .prj file (along with the .shp, .shx and .dbf)? That should definitively define the projection. Also, why not give QGIS a try?

comment On install “Couldn't load SIP module.” - should I reroute Python config or download sip?
That's quite an old Qgis - 2.0 is a lot newer and nicer. I'd suggest updating to the latest version from the ubuntugis repository.

comment convert data.frame with no lat-long info to a raster
If its just an adjustment to your question you should edit your question above rather than add an answer below - unless you are really answering your question!

comment Is there a good free Flat style map tile available?
By the time you've built your website, I reckon flat design won't be trendy any more... It's so 2013.

comment How to calculate position in a picture based on latitude/longitude
Just to clarify, your lat-long grid in your picture is a plane heading off to the horizon? In which case I think its impossible without knowing the field of view of the lens, and possibly other lens/view parameters too.
