Building Inspector by NYPL Labs

The New York Public Library has another cool digital project called the Building Inspector. They are crowdsourcing the training and correction of a building recognition tool that is combing through old maps. You see a portion of a map with red dots outlining a building and you click “Yes” (if the outline is correct), “No” (if it is wrong), and “Fix” (if it is close, but needs to be fixed.)

They also have a neat subtitle to the project, “Kill Time. Make History.”
