The American Congress on Surveying and Mapping (ACSM) was an American professional association representing the interests of those engaged in measuring and communicating geospatial data.
[1] Originally, it was composed of four organizations: During the 2000s, CaGIS and GLIS removed themselves from ACSM; in 2012, ACSM legally merged into the NSPS, while AAGS remained separate.
[3] It published the bimonthly ACSM Bulletin, no longer in publication.
ACSM also published the quarterly Surveying and Land Information Science (SaLIS) technical journal, now officially published by the AAGS.
