Welcome


Welcome to the Survey and Cartography Section's (SACS) website. SACS is an internal organization of the NSS whose purpose it is to improve the state of cave documentation and survey, cave data manipulation, and all forms of cave cartography.

SACS is made up of a diverse group of cavers who are interested in sharing ideas, technology and opinions on the science and art of producing digital and traditional cave maps, on methods of cave data collection and reduction, and for improving the digital manipulation and representation of cave survey data. Anyone interested in cave mapping and cartography is welcome to join.

The Section holds an Annual Meeting, a Survey and Cartography Session, and a Cartographic Salon at each NSS Convention. Section business is conducted at the annual meeting. Papers, presentations, and discussions are featured at the Convention session and the Cartographic Salon is an exhibit of traditional and digital cave maps which feature the best work of national and international cartographers.

Membership: SACS is no longer collecting dues as we currently have sufficient funds for current activities for many years, and we have decided to publish Compass & Tape as an electronic only publication, saving much of the annual costs of membership.  Please email the SACS Treasurer, Bob Hoke, bob@rhoke.net, your name & email address to become a member of SACS and be kept up-to-date on all upcoming activities.

NSS Convention Session:  SACS sponsors the Survey & Cartography Session at the annual National Speleological Society Convention, at which presentations are made on a variety of topics of interest to cave surveyors.  Anyone is welcome (and encouraged) to do a presentation at the session.  See the Call for Presentations for more information.

Cartographic Salon: At each NSS convention there is a Cartographic Salon where cave maps are displayed and judged in different categories.  For more information go to the Cartographic Salon Page on this site or  http://www.caves.org/committee/salons/Cartographic.shtml.

Call for Web-Based Maps: The Cartographic Salon welcomes web maps. With a real example to study, we might begin learning what a web map really is. Please let me know of any cave map that might qualify, your own or something you’ve seen on a web page somewhere. Check the Cartographic Salon Page for more information.
