WhirlyGlobe Component - Version 1.01

I've pushed a minor update to the Component and uploaded a corresponding binary distribution.

The update contains a few fairly minor fixes.  First, the big one.

There's, like, snow up there and stuff.

For Spherical Mercator based tile sets, you can turn on pole coverage and have it make up some polygons for the poles.  It picks the texture coordinate right in the middle, so whatever color you have there is the color you get.

The results depend a lot on what the images are doing.  It works well for some, not as well for others. But at least it's covered.

A user noticed that my extents for the web mercator projection were wrong.  That's now fixed and vector data will now correctly overlay.  I was wondering about that, but I hadn't gotten around to looking at it.  Let's hear it for users.

The component is now compiled for armv7s as well.  And, yay, the distribution got much bigger.

That's all in the master branch.  There's a lot of interesting stuff going on in the develop branch, which I'll post about soon.

State Of The Map USA - Portland

I'm presenting at SOTM in Portland this weekend.  It's a 25min talk on WhirlyGlobe and how I use OpenStreetMap data.

As promised, here are the slides.  Missing the videos, obviously, those are huge.

Data

The apps I show used a variety of free data sets.  Here they are.

• NASA Blue Marble, next generation for background imagery.
• Natural Earth Data for political boundaries, populated places, and water.
• OpenStreetMap for map tiles.
• United Nations Environment Programme for data used in WhirlyGraph.

Apps

As I mention in the talk, I can't show much of my work; my users can be secretive.  Of those users who are not, here is a sampling of interesting apps and a few of my test apps.

• Live Globe - A pretty geography app with linkages.
• Economist, World in Figures - An impressive idea.
• Tremor Tracker - A really cute iPad app showing recent earthquakes.
• WhirlyGraph - A goofy little data display app.
• WhirlyGlobe (the app) - Just my test app published to the app store.
• Xweather - Shows recent extreme weather events
