A poster for the Esri International Users Conference

Below is a snapshot of my poster for the map gallery at the Esri International Users Conference for GIS. The poster depicts Artistree: An iOS Location Based Marketing Application for Music Retail Stores.

The poster shows a typical use case for the app, at the bottom. The use case is illustrated and narrated by text and symbols on the left hand side. Each symbol represents a stage of Artistree’s application life cycle during a typical user’s story on an iPhone. There is also a map of some of the Esri Geotrigger event buffers, taken from Artistree’s Geotrigger Editor page on developer.esri.com, built around record stores I selected for testing the application’s functionality and responsiveness.

I hope the information on this graphic communicates the key features of Artistree, I will post a link to a larger file for viewing this poster in greater detail.

Thanks,

geoidnico

Loxodromes and Geodesics: Interesting distortions

I am taking a class on projections as part of an elective at the University of Redlands MS GIS program and I thought I would share some projections that created interesting distortions to loxodromic (rhumb lines) lines and geodesics (great circles). The projections themselves create interesting distortions on the shapes/areas of countries and continents of the world.

Loxodromic lines in magenta, Geodesic (great circle) lines in navy blue, straight lines in light blue. Let me know what you think

Isn’t this at the core of what we use geography and G.I.S. for?
