Hi Jeff, I am an amateur radio operator, and I am writing a little application to display where the major lobe of my antenna is pointing. I can control the direction of my antenna with the computer, and it would be nice to have a display of the whole world, as well as circles representing how far the station I am talking to is, and radial lines showing the bearings. I'd like to show the bearings along the edge of the map. For this type of map, a circle is a much better boundary than a square, but if it has to be a square, we should be able to make it a square bounding the circle, not the other way around. I think I can even plot the station's location given data I get from the Internet using this software. I am just learning Python, but it appears to be ideal for what I'm doing.
Right now I'm trying to figure out how to get the Eclipse IDE I am trying out to show me the source code for Basemap. :-) Thanks for the expert help!
