Geospatial Tool Building

My new article “The Right Tools for the Job: The Case for Spatial Science Tool-Building” has been published in Transactions in GIS (free PDF). I originally presented this paper as the 8th annual Transactions in GIS plenary address at the AAG annual meeting last year. I argue that tool-building is an essential but poorly incentivized component of academic geography and social science more broadly. To conduct better science, we need to build better tools. Better tools and data models, spearheaded by academics, can help infuse theory into our field’s quantitative work where it is too often lacking. But if we want better tools, we have to build them. It is not ESRI’s job to satisfy all the theoretical needs of the spatial sciences.

AnyConnect VPN on Linux

I run Linux on my school computer, which I brought home to get work done during the stay-at-home order. But when I tried to set up a VPN connection, I was surprised to discover that USC IT didn’t seem to provide a Linux client for Cisco AnyConnect. When I contacted them to ask how to connect, I was informed that “at this time IT doesn’t support Linux.” Shrug emoji.

Fortunately I do support Linux, so if anyone else wants to connect to the USC AnyConnect VPN, here’s how. You could roll your own solution using OpenConnect and a vpnc-script, but that’s complicated. Instead, you can download a current Linux client for Cisco AnyConnect here (you’re welcome). Install it and run it.

You want to connect to sslvpn.usc.edu (the normal vpn.usc.edu server does not work here). To log in, enter your normal USC username and password. For “second password” open your Duo Security app, generate a two-factor code, and enter it here. And ta-da, you’re in.

New Position at USC

I’m happy to announce that I have accepted a tenure-track offer from the University of Southern California as an assistant professor in the Sol Price School’s Department of Urban Planning and Spatial Analysis. I will be starting in the Fall and moving to Los Angeles later this summer! Looking forward to heading back home to California.

AAG Transactions in GIS Plenary

Manhattan, New York City, New York street network, bearing, orientation from OpenStreetMap mapped with OSMnx and PythonI am giving the Transactions in GIS plenary address at the AAG conference this afternoon. I’ll be reflecting on urban science, spatial networks, and tool-building in academia, focusing on OSMnx. A paper will be forthcoming soon, but in the meantime, for any interested plenary session attendees or other folks, here are a few links to more info and related resources:

Getting started

What is OSMnx? What does it do? Here’s a succinct overview.

The easiest way to get started with street network modeling and analysis in OSMnx is with this docker image and these example/tutorial Jupyter notebooks. The OSMnx software documentation is available here and this journal article introduces it more formally.

Spring Teaching

Happy new year! In the spring semester I’ll be teaching two new courses: Big Data for Cities and Advanced Spatial Analysis of Urban Systems. The former serves as a sort of gateway course to Northeastern’s urban informatics master’s program, introducing students to urban theories and scientific methods of analyzing urban data. The latter introduces advanced students to a computational workflow of spatial analysis and statistics with Python, PostGIS, and other open-source tools. I’ll be creating my lectures as Jupyter notebooks and will share a GitHub link soon when they’re all together.

Fall Conference Presentations

I’ve been traveling a lot over the past month, presenting my recent research at the Architect of the Future conference in Moscow, the Venice Biennale of Architecture, and the ACSP conference in Buffalo. At the first two, I shared my recent findings on how planners have used street networks to organize urban space according to an evolving set of spatial logics during the 20th century. At the third, I shared my findings on how technology platforms like Craigslist can shape rental housing markets and also shape how researchers and policymakers understand affordability. Both papers coming soon.

Looking ahead to the spring, in April I’ll be presenting at UAA in Los Angeles as well as a full slate at AAG in Washington, where I’ll give a paper talk, speak on an urban data science panel, and deliver the Transactions in GIS plenary address. See you there!

New Article: Craigslist Housing Markets in JPER

Our article “New Insights into Rental Housing Markets across the United States: Web Scraping and Analyzing Craigslist Rental Listings” is finally appearing in print in the Journal of Planning Education and Research‘s forthcoming winter issue. We collected, validated, and analyzed 11 million Craigslist rental listings to discover fine-grained patterns across metropolitan housing markets in the United States.

Map of 1.5 million Craigslist rental listings in the contiguous U.S., divided into quintiles by each listing's rent per square foot. Published in JPER: the Journal of Planning Education and Research.

New Article: OSMnx in CEUS

My article “OSMnx: New methods for acquiring, constructing, analyzing, and visualizing complex street networks” was published in the journal Computers, Environment and Urban Systems earlier this month. OSMnx is a Python package that lets you download a street network anywhere in the world at any scale with a single line of code, then analyze or visualize it with one more line of code.

OSMnx: Figure-ground diagrams of one square mile of each street network, from OpenStreetMap, made in Python with matplotlib, geopandas, and NetworkX
