I started this blog back in 2006 during a time when I wasn’t doing much geospatial work at all. I was working on building a human resources system for a federal government customer who was falling under the then-new and now-defunct National Security Personnel System. Because it was new and sufficiently different from the GS…

Geography, Geospatial, and GIS
I was participating in a Clubhouse discussion today when someone asked the about the distinction between GIS and geospatial. Since Clubhouse is audio-only, I am paraphrasing by contribution to that particular discussion here. I think the boundaries and definitions of these concepts are pretty blurry and I am reticent to create hard distinctions between them….
Reconsidering the Spreadsheet
I’m a CIO. That means a typical day can involve a range of activities: responding to data calls for security audits, reviewing SOC2 reports of prospective platform vendors, managing subscriptions of existing vendors, handling GDPR requests, ensuring data from corporate systems is meaningful and relevant for our internal stakeholders, attending meetings of various sorts. Somewhere…
Return on Non-Investment
Yesterday evening, I had the pleasure of participating in a panel discussion on Clubhouse, hosted by Todd Barr and Jordan Cullen, and including Will Cadell of SparkGeo. Clubhouse seems to be a really convenient venue for setting up such a forum with low barriers to entry, so that was enjoyable. The topic of the discussion…
Routing with BigQuery and ArcGIS Platform APIs
This post is a continuation of last month’s post about analyzing location change with BigQuery. At the end of that post, I was already thinking of ways to extend the analysis and visualization. I decided to take the opportunity to explore Esri’s recently-announced ArcGIS Platform APIs. These APIs are the same that have been available…
Analyzing Location Change Over Time in PostGIS
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…
