As I continued my experimentation with BigQuery, I found myself wanting to more easily use it with my regular GIS tool set. BigQuery has a lot of powerful analytic capability, but the SQL console is intimidating for the casual user and the GeoViewer tool is fairly limited. As I began digging deeper in my previous…

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…
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…
A Perhaps-Premature Recap of My Year
The calendar is inching up on the nine-year anniversary of this blog and it’s starting to feel like it’s been that long since I’ve actually written anything. It’s been an interesting year and the last couple of months have been no exception. It’s probably a bit early for a year-end recap but I feel the…

I went on family-related travel immediately afterward and could not sit down to collect my thoughts until…
Working with Node and the GeoServer REST Configuration API
I’ve been working with a mix of technologies lately that includes Node and GeoServer. I’ve recently begun integrating the two by using Node to manipulate GeoServer’s configuration through the REST API it provides for that purpose. One task I’ve been working on automating is the registration of vector layers stored in PostGIS with GeoServer to…
Getting Reacquainted With GeoServer
Over the past few weeks, I’ve had the opportunity to get back in touch with GeoServer. It used to figure more prominently in my toolbox but I got away from it because it simply didn’t factor into most of my project work. Time being a limited resource, it had to go on a shelf. I’m…
Simple Tile Viewer
We do a lot of tiles for various customers at Zekiah. Tiling is as much art as science and sometimes things go wrong so we have a range of utilities that we use to perform various kids of QA. Because the caches can be large, we usually want to perform a visual QA on the…
