More to maps than markers

Posted by: Will Cadell in esri user experience mapping web development code gdal postgis GIS open source tools google maps consulting leaflet 2 years, 7 months ago

Google Maps have been with us since February 2005, virtually a decade ago as I write this (expect a party on Feb 8th 2015). From their acquisitions of Where 2 Technologies and Keyhole, Google ignited a cartographic web revolution. Yes, of course there were maps on the internet pre-Google Maps, but Google brought the web map to the consumer, and has driven the expectation of location intelligence in web and mobile apps ever since.

So I wrote up the process I used to make it all available on a Google Map. The process involves the use of PostGIS, Mapnik, Node.js and just a smidge of magic. Its a longer post, so i lumped it in with my tutorials. You can go check it out here.

Building a US Census Tracts PostGIS Database

Posted by: Will Cadell in postgis technology open source tools ogr2ogr 4 years, 3 months ago

This article shows how you (yes, you!) can build your very own US Census Tracts PostGIS database. I had looked over the interwebs for some time under the false assumption that someone, somewhere would have already done this, but it seems not. So this article documents my process. I am running a mac, so some things could be done faster / smarter using other technology refinements, but I have tried to keep things pretty generic for 'nix users. Windows people; you will find this process is pretty simple, I am sure you can replicate it using what you have available.
