Recently, I had the occasion to attempt to generate an OGC GeoPackage from QGIS and publish it using GeoServer. The use case was fairly straightforward. I had been given data in GML format and needed to publish it. For many valid reasons (such as lack of spatial indexing), GeoServer does not natively support publishing GML…
Esri User Conference 2016
Aside from a day at the Esri Federal GIS Conference, I’ve been laying fairly low from geo industry events for about the past year. There’s no single reason for that; it’s been more that a combination of things like work deadlines or family happenings have taken priority over conflicting conferences and events. I’ve generally been…
Revisiting Two Old Friends: ArcGIS and PostGIS
Back in the dark old days of ArcSDE, when it first started to support PostgreSQL/PostGIS as a back-end data store, I did a series of posts about how to work with it. Of course, working with PostGIS in ArcGIS was a theme of the early days of this blog, through my association with zigGIS. Although it’s…
A Week in the Life of a Geotech Omnivore
Consulting is enjoyable due to the variety, but it would be fun to help build a platform. — Bill Dollins (@billdollins) May 2, 2016 Earlier this week, I posted the above tweet. To explain the variety I referred to, here is a partial list, in no particular order, of the tools I’ve worked with in the…
Client Certificates In a Desktop Application
Lately, I’ve been working on a project that involved retrofitting authentication via client certificates, similar to CAC/PIV smart card authentication, into an existing set of Windows Communication Foundation (WCF) web services and a desktop (yes, desktop) client application that was designed to interact with them. The first part was pretty easy to figure out; the…
The Consultant’s Dilemma
I’ve worked as a consultant for my entire career, and one of the most rewarding aspects of it is the variety of projects you get exposed to. I’ve gotten to meet and work with great people over the years and have also gotten to work with a lot of emerging technology. In that regard, it’s…
Working with HIFLD Open Data
I finally had a little time to play with some of the data available through the HIFLD Open site. For my first pass, I decided to have a little fun by estimating how much of the United States a driver could cover in an electric vehicle while remaining in range of a charging station. For…
HIFLD Open
Among the many things I did at the Esri Federal GIS Conference was that I attended the Homeland Infrastructure Foundation-Level Data (HIFLD) community meeting. HIFLD is now an FGDC Subcommittee, being led my Mr. David Alexander, head of the Department of Homeland Security (DHS) Geospatial Management Office (GMO). Now that the alphabet soup is out…
My Path to GIS
TL;DR: This post is long and there is no summary. When you reach a certain stage in your career, you start fielding more and more inquiries from those younger than you about how you got started in your field. In my case, the field is GIS. The short answer, and not a particularly uncommon one,…
Extending Hibernate Spatial
Java is my “Groundhog Day” language. It’s one that I use just infrequently enough to feel like I’m starting over every time a new requirement pops up. As a result of planning the system migration I discussed in my last post, I’ve been doing some work with it, which is my first sustained Java work since…
