tutorial three :: advanced [???] topics
feet
Titled "advanced," this section deals with more GIS-type functions. I'm not sure that this is more advanced than the other two tutorials, so much as it is less essential to getting your first mashup out there.
Goals: add tools to calculate distance, work with polylines, change color of selected marker, select markers based on an arbitrary distance [spatial query], and aggregate and display summary data.
