Hello World Wind – Basic World Wind Java SDK Tutorial
I am just getting started on an application that uses the World Wind Java SDK. As I learn more about it I will post tips and lessons, more for myself as a reminder of how I did something, but maybe someone else will find use of them. This lesson will be a very simple Hello World. I will explain how to get the WWJ SDK going in NetBeans in this article. (more…)
Ruby Polyline Decoder For Google Maps
As promised I have finished the ruby polyline decoder. This class will take an encoded polyline and decode it returning an array of latitude and longitude values. This one gave me a headache. Hope you can find use of it. Please take time to tell me the projects you are using it for, I’m just nosy. (more…)

It’s got me thinking about other possibilities for future additions to nomadexplorers.com and other fun projects. Here are some notes one a few of the data sources I have found. (more…)
Ruby Polyline Encoder for Google Maps
I wrote this translation of the PolylineEncoder.js by Mark McClure because I needed a way to create encoded polylines for Google maps. When I first started my project – http://nomadexplorers.com.
I tried using an existing ruby translation of PolylineEncoder.js. It was giving me some errors when I tried using it and it only took an array of coordinates. For my needs I needed the class to accept an array of objects. This seems a bit more elegant to me. Also, in the notes that where provided in the class comments, it appeared to have a bug that would incorrectly encode the second point. So instead of trying to debug and rewrite their code, I just decided to do my own implementation. (more…)
