Geographic information literacy (GIL) is defined as the possession of concepts, abilities and habits of mind that allow an individual to understand and use geographic information properly. This paper reports the results of an online survey undertaken to get expert input into specifying the concepts and abilities associated with GIL that should be in the K-12 curriculum to ensure coverage of geographic information skills required to be literate in an information society. The survey differentiates traditional geographic information literacy, general information literacy, and digital geographic information literacy. Replies from respondents (N = 80) were used to classify and rank GIL concepts and abilities. (Contains 6 tables and 2 figures.)
