By doing this little project, i’ve learned about writing XML documents and how easy it can be and how big of a pain it could be.  Also this project stresses the way I used to code.  For example, a 750 KB file with 6,000 data points works flawlessly.  Toss in a 10 meg file with 54,000 data points and  you will see real quick that handling data is alot different.

Things I’ve Learned:

• Redim Preserve statement is a bad bad bad idea if called once per loop.  It basically creates an array thats bigger (or smaller), copies the old array to the new array (2x memeory consumption), then destroys the old array.
• Better to Add items all at once vs one at a time on List View Boxes (still learning to program this one).
• Google Earth is picky when it comes to <document> and <Document> …

This program for the most part is complete, once I fine tune it and get everything running smoothly, I will see about the website side of this project. 

Below is what I picked up for just the gadsden area. The data was thrown into Google Earth, and needs to be cleaned up as there are probably 5-10 Access Point data per spot and it gets confusing.

A red X is a secure Access Point, a green check is an open wifi hot spot.
