I got an interesting e-mail the other day informing me about the “Roads to Rome” project. I don’t normally write items that arrive in my inbox, but this had two major hooks for me. First, I used to do a lot of routing analysis earlier in my career. Second, I am a Roman history buff….

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…
How long until the ads stop?
In celebration of this day when the non-stop political ads, robo-calls, junk mail, and social media posts *should* finally come to an end. I threw together a little map to show the latest time at which polls close in each state. This should represent, state-by-state, the time (EST) at which you can safely go back…
Mapping GISPs Again With Leaflet.markercluster
So I’ve been playing with Leaflet a lot lately. It’s become my lightweight mapping library of choice. There’s a lot it doesn’t do so I keep OpenLayers and others in the rotation as well but Leaflet is direct and to the point so I use it when I can. A while back, I stumbled onto…
CartoDB/Leaflet Sample Update
A while back, I posted about some experimentation I did with Leaflet and CartoDB in the wake of FOSS4G in Denver. I recently had the chance to go back and update that sample with some spatial queries. At the time of the original post, CartoDB was still in beta and spatial queries didn’t seem to…
Breaking Radio Silence
Things have been kind of quiet on the blog lately due to things being busy at work. I call that a good problem to have. Since the beginning of the year, I’ve written a a lot of proposals for a mixture of potential customers. Interestingly, I’m seeing a lot more call for “GIS Analyst” work….
ArcGIS Image Services and Leaflet
I’ve become a big fan of Leaflet for putting maps on the web. It gives me most of what I need without much of what I don’t and is fairly easily extended, as shown by the impressive work of Jason Sanford. A while back, Dave Bouwman blogged about work he and the team at DTS…
A Busy Day for Releases
3 April 2012 was a busy day for releases/announcements in the geospatial field: PostGIS 2.0 – This long-anticipated major version of PostGIS was announced with advanced features such as raster, topology, and 3D/4D indexing. Many have been using 2.0 for a while but the official release gives top-cover to organizations, such as some government agencies,…
CartoDB + Leaflet = Easy
One of the biggest sources of buzz at FOSS4G was CartoDB. It is a hosted solution from Vizzuality that uses PostGIS to allow you to store your spatial data online. I got a beta account a couple of weeks ago but life (i.e. paying work) kept getting in the way but I finally got to…
