“An exciting addition to the mapping project is Mapping Challenges. The Challenges asks volunteers to concentrate on specific areas and structure types that need updating. In addition, Challenges encourage volunteers to remain engaged, and incentivizes participation. Once a need is determined, a call to action goes out to the volunteer corps with information on the geographic location and the type of structures that needs updating. Volunteers who participate can earn a series of virtual recognition badges and are recognized on social media and TNMCorps project site.”
