Sonification is the use of sound and speech to represent information. There are many sonification examples in the literature from simple realizations such as a Geiger counter to representations of complex geological features. The data that is being represented can be either spatial or non-spatial. Specifically, spatial data contains positional information; the position either refers to an exact...

Spatial data infrastructure (SDI) is the infrastructure that facilitates the discovery, access, management, distribution, reuse, and preservation of digital geospatial resources. These resources may include maps, data, geospatial services, and tools. As cyberinfrastructures, SDIs are similar to other infrastructures, such as water supplies and transportation networks, since they play fundamenta...

Global positioning systems (GPSs) and geographical information systems (GISs) have been widely used to collect and synthesize spatial data from a variety of sources. New advances in satellite imagery and remote sensing now permit scientists to access spatial data at several different resolutions. The Internet facilitates fast and easy data acquisition. In any one study, several different types ...
