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?
