In 1968, a group of geographers led by William Bunge founded the Detroit Geographical Expedition and Institute (DGEI), a methodology based on teaching neighborhood residents the skills of a folk geographer to help them improve their built environments. This article focuses on the necessity of revisiting the geographical expedition format today and its influence on participatory urban planning practices and advocacy mapping. After looking at DGEI’s activities in the Detroit neighborhood of Fitzgerald, I then focus on two specific elements in direct relation to the field of urban planning: that of communal participation and that of the map-making process itself.

1968年，由威廉·邦格（William Bunge）领导的一组地理学家创立了底特律地理探险与研究所（DGEI），该方法基于向邻里居民传授民间地理学家的技能来帮助他们改善建筑环境的方法。本文重点讨论了重新审视当今地理探险格式的必要性及其对参与式城市规划实践和倡导制图的影响。在考察了DGEI在底特律菲茨杰拉德附近的活动之后，我将重点关注与城市规划领域直接相关的两个特定要素：社区参与和地图制作过程本身。
