There is a song by DJ Fresh called Mindtunes that was created by mapping the brainwaves of disabled patients to a musical scale. There is also a track called Brainwaves that was record for the Voyager Space Mission and is included as track 4 on the Golden Record.
In physics, quantization is the process of explaining a classical understanding of physical phenomena in terms of a newer understanding known as "quantum mechanics". It is a procedure for constructing a quantum field theory starting from a classical field theory. In digital signal processing, quantization is the process of approximating ("mapping") a continuous range of values (or a very large set of possible discrete values) by a relatively small ("finite") set of ("values which can still take on continuous range") discrete symbols or integer values. In digital music processing technology, quantization is the process of aligning a set of musical notes to a precise setting. This results in notes being set on beats and on exact fractions of beats. Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum value. When the number of discrete symbols in a given stream is reduced, the stream becomes more compressible. In linguistics, a quantized expression is such that, whenever it is true of some entity, it is not true of any proper subparts of that entity. Example: If something is an "apple", then no proper subpart of that thing is an "apple".
Besides the basic measurement technology applied, choosing the best magnetometer for your application should include many other criteria:Field component or field magnitude measurement: devices can measure 1, 2 or 3 components of the magnetic field, or an absolute field magnitude.Measurement speed: this ranges from quasi-instantaneous - e.g. Hall devices - to many seconds - e.g. flux-meters with moving coils.Frequency response: one distinguishes between DC applications - e.g. mapping static fields - and AC applications - e.g. ELF and VLF leakage measurements.Temperature range: in particular, suitability for cryogenic applications.Packaging: common configurations include hand-held, bench-top or rack-mount.Interfaces: these include interfaces to external probes or sense coils, computer interfaces, and interfaces for trigger signals.Probe dimensions and characteristics: most applications are in some way constrained by the probe dimensions, ruggedness, cabling, etc.Measurement volume: most devices attempt to measure the field strength at a single point, but some special-purpose devices are designed to measure an integrated field along a given path or volume.Top

Digital mapping is much more accuate because of satelite technology and themeral imaging.

To map body tissues, MRI (Magnetic Resonance Imaging) uses a combination of techniques: a powerful magnetic field, and radio waves. Radio waves are utilized for mapping because they will not damage the body tissue.

Satellite imaging is used by various organizations and industries, including government agencies for urban planning, disaster response, and environmental monitoring; companies for mapping, agriculture, and infrastructure development; and researchers for scientific studies such as climate change, deforestation, and archaeology. Additionally, satellite imaging is commonly used in the military for intelligence gathering and reconnaissance purposes.
The mapping of the stars, or astronomy, created solid documentation that allowed those who traveled the seas to identify whether they were on the correct path or not.
