Only 400 Million Maps? We've Got ESRI Beat!

Postitas iandees kuupäeval 23. detsember 2010 – English.

Yesterday Tim O'Reilly made some waves by posting a tweet from within ESRI who claimed that they served 400 million user-generated maps in October. Needless to say, this number was called into question by those that heard it.

My theory (along with other commentors and tweeters) is that they are counting each map tile generated for this number. Based on this assumption I asked User:Firefishy to dump some logs from the main tile server so we could compare our "map generation" statistics with theirs.

Let's look at the graph:

Tile Server Request Graph

For the last two months, our tile servers "generated" 50-75M "maps" each day. Over the course of those two months we served over 3.7 billion maps.

I think we win, ESRI.

You need substantially more than 1 tile to make a map of decent size. I think that this statistic is meaningless, sorry.

@andrewpmk: ESRI didn't claim any size when it confirmed the 400M for its map count. Each OpenStreetMap tile is indeed a discrete map, so I counted it that way.

Later that day, Tim "believed" it was cumulative. http://twitter.com/timoreilly/status/17383552760938496

Awesome graph, how many edits each day?
