The "noninvasive'' GPR technology has been used in recent years in many archaeological explorations around the globe, including Port Royal, Jamaica, destroyed by a 1692 earthquake, lost cemeteries and battlefields of various wars.

Often described as one of several "squatters camps'' of huts and shacks that were displaced by the building of Central Park, Seneca Village actually was a more permanent and well-ordered community, with three churches, a school and some inhabitants who owned their property, experts now say.
Although founded by free Blacks, it later became a multiethnic settlement that included Irish and German immigrants and possibly some American Indians, according to various historical sources.
