GeoCoding Again

Tonight we got globalized again. This time it was much less intense as we just briefly visited the blog of Pam Silvers who is Pete's boss and my friend and IT mentor. She is in India on another sort of exchange program like the one that sent Pete to Mexico a few weeks ago.

Next we learned about Geocoding and watched Pete demo the process. It's a way to turn text data into a location on the map. It is a powerful technique. Usually it takes an address and converts it into latitude and longitude and sticks it int he right place on the map. It is the way that you can put your address in an internet map site and have it find where your house actually is. We did this exercise:
We created an address locator for the whole state of SC and then used it to digest a big list of student addresses from a college in the Upstate. You can see most of them are clustered up there around Greenville. Sometimes parts of the data is not accurate and it can't figure out where to put an address. Then you can painstakingly fix the problems. Fortunately, we didn't have to do that for this exercise. That looks quite tedious.

Since I was all in the SC Street Centerlines file, I zoomed in on the sea shore area where I will visit with my sweetheart on spring break. I'm excited about that.
