Registration to the SIGSPATIAL 2023 conference comes with a free one-year SIGSPATIAL membership. As a member, you can optionally join our low-volume email list for the earliest official SIGSPATIAL announcements and other opportunities. SIGSPATIAL members receive reduced registration costs for our annual conference. If you are already an ACM member, we will add SIGSPATIAL to your membership. If you are not an ACM member, you will receive an affiliate membership in SIGSPATIAL. If you are already a SIGSPATIAL member, this option will not affect your membership. The free, one-year memberships will not auto-renew, and they will begin after our 2023 conference, so joining in this way will not qualify you for the reduced registration cost this year.

If you wish to obtain a SIGSPATIAL membership prior to the registration, please use this link.
