This is a project I made for an article on my blog. It demonstrates measurement of a celestial object's elevation. I thought some elements in it could be useful to others. It includes other images from OpenClipart: "Compass Rose" by SeriousTux, "Satellite Icon" by uroesch, and "Little Green Alien" by laurent. EDIT: After uploading, I realized that my logo (AeroSavvy) runs off the image. This is due to the font I used that resides on my computer.
