Members of the American Society of Photogrammetry (ASP) and members of the American Congress on Surveying and Mapping (ACSM) have rejected a plan to consolidate the two societies.

An affirmative vote of at least two-thirds of each society's members present or represented by proxy was required for the merger. Voting in favor of the consolidation plan were 61.2% of ASP voters and 63.7% of ACSM voters. Almost 50% of eligible members of each society participated in the September 21 vote.
