Following up on my previous post, I decided to attempt the same analysis in PostgreSQL. The analysis doesn’t make use of any spatial logic itself (yet), but I consider this a PostGIS post because it is using PostGIS geometries. In the past, I have noticed that BigQuery SQL is very reminiscent of that of PostgreSQL,…

Analyzing Location Change Over Time in BigQuery
I’ve recently spent a lot of time doing various forms of business analytics in BigQuery. As discussed in a previous post, I’ve been using BigQuery as the data integration environment for several business systems. I’ve found integration at the data level via an ETL/ELT/IPaaS pipeline to be a lot more stable than system-level integrations that…
Lately…
These are some of the things I’ve been up to lately, while the blog has been quiet: At work, I’ve continued delving into BigQuery. Our FME jobs are running like clockwork and I’ve been spending a lot of time writing queries and doing analysis for various stakeholders across the company. The next phase of the…
FME, Salesforce, and BigQuery
More often that not in my current role, opportunities to get my hands dirty come from the data side of our operation rather than the engineering side. These days, the data side involves corporate data rather than a lot of geospatial data. If I were to be guided by my own personal inertia, I’d drift…
Attribute Transfer in PostGIS Using Spatial SQL
Data conflation is a meat-and-potatoes task in most GIS workflows. There are numerous reasons one might need to get data from one data set into another. Perhaps you want to attach a new geometry type to existing attributes or a table. Or maybe you need to pull attributes from one or more data sets into…
Watching COVID-19 Data for Your County with PostgreSQL and Node
I have addressed the topic of triggered notifications a couple of times on this blog previously. I’ve taken the opportunity to apply the technique to a current use case – the ability to get notifications whenever the confirmed count of COVID-19 cases changes in my county or surrounding ones. I am basing this workflow on…
Fulcrum Query API and Koop
I don’t write code as much as I used to, but I have to return to it every so often to keep my sanity. With the current world situation, there are a lot of dashboards going up, many of which are based on the Esri Operations Dashboard or ArcGIS Hub. I got thinking about a…
Milestones, Goals, and the Power of No
It’s been a few weeks since I hit my latest milestone, but life was fairly full in the immediate aftermath. On the plus side, the extra time was good for reflection. The milestone to which I am referring is that, on October 27, 2019, I ran the Marine Corps Marathon in Washington, DC. The race…
Ron Lake – The Man In the Arena
It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who…
Hello, Discipline, My Old Friend
It wasn’t that long ago that I was “always on” in terms of work. There is a certain ethos in the DC area that rewards that outlook and I was fairly good at it. This was compounded by the fact that I was a partner in my company and the buck always stops with the…
