Spatio-Temporal (ST) Questions • How do we conceptualize spatio-temporal (ST) worlds? • How do we measure ST concepts, recognize them in (remotely) sensed information or in the field, and identify their accuracy and quality? • How do we represent ST concepts with incomplete/ uncertain information, with alternative data models, and possibly with multiple representations for the same data, in digital environments? • How do we store, access, and transform ST concepts, facilitating data sharing, data transfer, and data archiving, while ensuring minimum information loss? • How do we explain ST phenomena through the application of appropriate methods of forward or inverse models of physical and human processes? • How do we visualize ST concepts on a variety of media such as maps on electronic displays or animated displays ? • How do we use ST concepts to think about spatio-temporal phenomena, and to seek explanations for spatio-temporal patterns and phenomena? • Source: Adaptation from NCGIA proposal to NSF by Goodchild et al.
