PostGIS Cookbook in the works
I promised not to reveal this until first drafts were all submitted, but I’m enthusiastic to say that a PostGIS Cookbook is in the works that I’m coauthoring. Paolo Corti has the lion share of chapters, I am writing 4, Bborie Park has written a couple, as well as a nice chapter by Tom Kraft.

Way beyond red-dot fever– bees hives and overlapping home ranges
Last week, post Boston Code Sprint, I spent a couple of hours playing with bee data, specifically bee keeper data for Norfolk County Massachusetts. My friend Eric (a bee keeper of 4 hives in said county) says that worker bees can fly as far as 3 miles for nectar, but after that approximate limit, they hit diminishing returns relative to the calories they burn. Proximity … Continue reading Way beyond red-dot fever– bees hives and overlapping home ranges
Solarized
I have been intending to use Ethan Schoonover’s Solarized (http://ethanschoonover.com/solarized) colors for vim for development work for a while now, and finally got around to adding it to my profile on my laptop. What is nice about the colors is they are meant to be distinguishable in the terminal without using excessive contrast– color is the primary distinguishing element. It makes writing or reading on … Continue reading Solarized

3D Renderers– a woefully incomplete survey
Recent exploration into PostGIS 3D tools has reminded me of my love of renderers. First, there’s PovRay. PovRay is and always will be my first love. I’ve done so many fun things with it. In short, PovRay is a mathematicians renderer– mathematical primitives, advanced ray tracing tools, and a C-like control language make for an abstract but powerful environment. I like to use it with … Continue reading 3D Renderers– a woefully incomplete survey
A little texture that needs composited
What is GIS? Why after 30+ years, do I feel like the field has an identity crisis?
A few of great articles/presentation have come out recently(ish) on the nature of geospatial industry identity. 3 of note: 1) Paul Ramsey’s talk: Spatial IT & the Spatial Web 2) Brian Timoney’s post: If Mapping is So Big, Why Does GIS Feel So Small? 3) James Fee’s short, but (apparently) inflammatory post: Goes Without Saying These three sources are highlighting aspects of GIS/Geospatial industry’s shifting … Continue reading What is GIS? Why after 30+ years, do I feel like the field has an identity crisis?
Independence– Free as in Freedom, part II
A friend of mine read my first post “Independence– Free as in Freedom” and said this: “awesome blog and great post. did jack respond?” My response: “Nooo. I think I’m unknown in the ESRI world …. But it was a heartfelt post. I think Jack has changed the world, but recognize it has changed him. I’m pulling for that organization to radically re-invent itself. The … Continue reading Independence– Free as in Freedom, part II
