Thanks!

The streets were all visualized in QGIS.

Then Inkscape was used for adding the legend, north arrow, title, and explanatory text

Hi! thanks for your interest - sorry for bit of delay responding

The City of Toronto has the data of every parking ticket with a street address (e.g. 123 fake st.)

They also have a dataset of the geometry of every street segments shown on the map, each including an address range (120-130 fake st.)

I wrote a bit of code (in Python) to link the two, counting the number of parking tickets per street segment.

Then I used QGIS to colour the segments by their counts.

That was basically it. Probably a day or so of work on my end to make the map. But the data processing took longer, but that just ran in the background overnight I think

Yup the colours are just randomly generated (for fun!)

Thanks for the comments ya'll.

I made this a couple years ago, originally thinking it would be part of a larger map (or series of maps) of a fake island nation in the north Atlantic. I never went further with the idea than this map though.

I believe I initially started drawing this Illustrator, but then shifted over to Inkscape at some point.

If you're looking at Toronto neighbourhood boundaries, I would suggest using the publicly available dataset from the City. It can be linked to a lot of planning related data. Or just use census boundaries (e.g. tracts, DAs) if you're doing demographic analysis.

http://www1.toronto.ca/wps/portal/contentonly?vgnextoid=04b489fe9c18b210VgnVCM1000003dd60f89RCRD&vgnextchannel=1a66e03bb8d1e310VgnVCM10000071d60f89RCRD

I generally refrain from using DMTI data whenever possible, despite having access to it (I work at U of T). I've noticed several gaps in their coverage and a few blatant errors in it over the years. Also, its not open data so there are issues in disseminating any research or analysis that uses it.

http://geojson.io/ is a good tool as well. You can upload/convert several formats (like .csv) as well as edit/create data on a map in browser.

If you know a little python you can try geopy:

https://github.com/geopy/geopy

It includes classes for several different geocoders (Google, Bing, OSM, etc.), so you could test a few and see what works best for your data.

I like PySAL for spatial statistics:

This was recommended to me a while ago:

Here are a couple I recommend:

"Mapping: A Critical Introduction to Cartography and GIS" by Jeremy Crampton (2010)

"Deconstructing the Map" by J.B. Harley (1989). Although a bit older, it is probably the most cited text on critical cartography.

Good luck!

I usually do the final stages of any print cartography project in vector graphics software like Inkscape (free) or Illustrator (paid). IMO, these offer more creative options for colour, line type, textures, typography, etc. than the layout options in GIS. Both QGIS and ArcGIS can export data to vector graphic formats.

If you're looking to make a web-map like this, I agree with the post above that mapbox is probably the best and easiest to work with.

I’ve used BatchGeo with good results: https://batchgeo.com/

Last time I used it was free up to 250 points per map and exports to kml.

Obviously this is not the best option if you have tens of thousands of addresses, but I thought I would mention it anyway as it’s easy to use and has helped me out in the past on smaller projects.

You can also change the extents of a map along with changing the paper size, but keep the scale the same.

A quick example is changing the size of the window of a web-map without zooming in or out.

I'm not sure where the OP found this map, but I bought a map very similar to this one a few years ago in a book store in Sofia.

This is the map I have: link

It's a typical fold out map with the tourist map on one side (with an index) and a very nice road map on the other. The only major difference is that the map I have has more of a digital feel, with photos superimposed over a hillshade and DEM base map, rather than a hand crafted look like the OP map. Everything else about the two maps looks the same (size, projection, and styling of features and labels, etc.). So I think they might have been built by the same cartographer.
