Hi Jean Ann Rodine.
I am sorry you seem confused by the instructions provided. In the first paragraph of the instructions, it states, "The URL provided in your invitation (a MOOC announcement, an e-mail, a tweet, etc.) is the actual page where the discussion will occur on the date noted."
This particular discussion where you made your comment is the actual Cartography. MOOC AMA. No need to search for an AMA page within GeoNet. Simply bookmark or follow this discussion. See image to the right.
The Action menu is just below the pencil at next to your avatar at the top-right of the discussion. Click Follow, where you want to receive notifications, and/or Bookmark so you can find the discussion easier in the future.
Each time a comment or question is posted you will then receive a notification it has been updated with a new comment of change. If you are following the discussion thread the day of the event, you can refresh your screen and see new answers and questions posted during the event.
You can also find the link at the top of the Cartography. MOOC page in the Announcement above the content just below the GeoNet navigation.
I hope this information helps and that you are able to join us on May 15th for the Cartography. MOOC AMA.
Delighted to be of service,
Candace Loya, GeoNet Community Content Manager
Ken talked about Normalization problems in cartography. Here is a potential example. This morning's Wall Street Journal has a map showing the number of oil rigs in the various oil basin in the western US. The graphic data is not normalized so it appears there is a very large amount of drilling activity (463 rigs) in the Permian Basin, compared to the small activity (70 rigs) in the Cana Woodford Basin. However, if one compared the normalized drilling activity in the huge area of the Permian Basin covering west Texas and parts of Mexico and New Mexico with the very smallest Cana Woodford Basin using area as a divisor, one would see that the Cana Woodford Basin is one of the hottest drilling areas in the US.
Thank you Jon, this is a great example.
Just to go a step further, another way to normalize the data might be by looking at the number of pipe feet needed for drilling. So many rigs over so many feet of pipe. Or maybe the inverse, the number of pipe feet per the number of rigs. There are multiple ways to normalize data, not just dividing by area. It once again boils down to what it is you want to show or try to explain.
Thanks. Here is the exhibit I referenced.
The oil driling company, Baker Hughes, the source of the exhibit, probably did not have or want to share the normalizing data you describe.
But as a MOOC student if I knew where to get a file showing the location of the oil basins in the western US, along with some attribute data I could show where are the hottest places to drill.
That map actually has a series of small multiple icons - it's a technique called isotype so it doesn't suffer from the lack of normalization. It uses repetition to portray the differences in magnitude.
1. I was taking art classes and geography classes in college. Then I took a GIS class and was obsessed. So I majored in geography with an emphasis on the "techniques" (GIS, Remote Sensing, Cartography). I liked cartography best.
2. A map of mine landed in National Geographic the day of my mom's memorial. Dad and I walked up to the mailbox and saw it there together. It was a good moment, and helpful for us both.
3. Hmmmm. Too many!
4. Hmmmm. Too hard!
Maybe don't pick an absolute favorite piece of work you created, but what are some techniques you've used most successfully? Anything you've been most excited about recently?
