They have some Pitcher Cards which show pitch f/x data as well as pitch selection data that are cool enough but the coolest thing they have is:

Major League Gameday BIP location

Select a park to grab hits from and a park on which to display them. Every hit is scaled (roughly) to the chosen park to display upon. Things like atmosphere effects or interaction with the walls are completely ignored since I lack the data to properly map the hits to the new field. Every location is where the ball was fielded by a player, not where it landed.

Optionally, you can filter which hits should be displayed by pitcher and/or batter. Most combinations will have few or zero hits. The selections will remain if you change the park you are displaying on, but will be reset if you pick a new park to select hits from.

Use the legend on the right-hand side to select which hits to display. Because the variety of events recorded in the data, some coalescing of events was done. For instance, sacrifice flies are considered to be fly outs while force outs, GIDP, and fielders choice outs are considered to be ground outs. The color corresponds to the run value of each type of hit. The mapping is not linear because there was too much similarity between the colors.

Of course the BIG problem with taking batted balls, adjusting them for atmospherics, and then superimposing them onto another ball park is this:

Batters and pitchers, I believe, pitch to the strengths and the weaknesses of the park. And the batting eye, visibility and the size of the foul territory of a park can significantly affect the character of the batted balls. The other problem is the atmospheric one. No one seems to know the real wind patterns inside of any park. That can be a pretty big problem. Basically, it is not as easy and clean as you might think. Trust me, I’ve tried it…

This is a great tool, but I have a feeling that people are going to misinterpret it a lot. Gameday measures where the ball was eventually fielded, not where it landed, and that makes a huge difference with in play hits that could be superimposed. If Sean could put a note saying this on the top of the web tool, that would be awesome.

Just some things to keep in mind with this tool.
