Category: Jens von Bergmann

You might have already seen Jens von Bergmann’s interactive map of Vancouver which integrates a ton of different data sets. It’s really useful for looking up zoning, year of construction, tax data, and even the estimated amount of floor space in buildings. I find it essential for understanding the city.

It has also has a great feature that many people don’t know about: the ability to filter data for better visualization through the use of a query parameter in the URL. With Jens’s permission, I’ve compiled a list of ways to use this.

Basics

Say you want to see the impact of Vancouver’s early building boom, circa 1905-1914. Just add a years_1905_1914 filter to the URL like so: https://mountainmath.ca/map/assessment?filter=[years_1905_1914]:

And those are just the buildings still left standing! It’s pretty wild how Mount Pleasant, Grandview-Woodland, and Shaughnessy all sprung into existence in a decade.

If you wanted to see all buildings with an estimated floor space ratio (FSR) between 0 and 1, add a fsr_0.0_1.0 filter: https://mountainmath.ca/map/assessment?filter=[fsr_0.0_1.0]

Filters can easily be combined with a comma. If you wanted buildings that were built between 1900-1940 and are between 0 and 1 FSR, the URL would look like this: https://mountainmath.ca/map/assessment?filter=[fsr_0.0_1.0,years_1900_1940]
