Why is temporal resolution important?
13.3.1.6 Temporal resolution. Temporal resolution is an important factor of remote sensing techniques which can image a picture of a targeted area or object. Landsat is a nadir sensor, but it can take images of objects or areas which are perpendicular to the surface of the Earth and, even after 14 days, it can sense the same place.

Satellites can be placed in several types of orbits around Earth. The three common classes of orbits are low-Earth orbit (approximately 160 to 2,000 km above Earth), medium-Earth orbit (approximately 2,000 to 35,500 km above Earth), and high-Earth orbit (above 35,500 km above Earth). Satellites orbiting at 35,786 km are at an altitude at which thei...
Electromagnetic energy, produced by the vibration of charged particles, travels in the form of waves through the atmosphere and the vacuum of space. These waves have different wavelengths (the distance from wave crest to wave crest) and frequencies; a shorter wavelength means a higher frequency. Some, like radio, microwave, and infrared waves, have...
Sensors, or instruments, aboard satellites and aircraft use the Sun as a source of illumination or provide their own source of illumination, measuring energy that is reflected back. Sensors that use natural energy from the Sun are called passive sensors; those that provide their own source of energy are called active sensors. Passive sensors includ...
Resolution plays a role in how data from a sensor can be used. Resolution can vary depending on the satellite’s orbit and sensor design. There are four types of resolution to consider for any dataset—radiometric, spatial, spectral, and temporal. Radiometric resolution is the amount of information in each pixel, that is, the number of bits represent...
Remote sensing data acquired from instruments aboard satellites require processing before the data are usable by most researchers and applied science users. Most raw NASA Earth observation satellite data (Level 0, see data processing levels) are processed at NASA's Science Investigator-led Processing Systems (SIPS) facilities. All data are processe...
To aid in getting started with applications-based research using remotely-sensed data, Data Pathfindersprovide a data product selection guide focused on specific science disciplines and application areas, such as those mentioned above. Pathfinders provide direct links to the most commonly-used datasets and data products from NASA’s Earth science da...
This article describes the main characteristics of auditory temporal resolution, and elucidates the specific mechanisms that process fluctuations in the temporal envelope. It begins with a summary of different measures of temporal resolution, followed by a broader view of temporal resolution by briefly discussing a study on pitch and one on ...
Sep 14, 2023 · Studies with temporal or spatial resolution are crucial to understand the molecular dynamics and spatial dependencies underlying a biological process or system. With advances in high-throughput ...
Apr 22, 2014 · In addition to spatial, spectral, and radiometric resolution, the concept of temporal resolution is also important to consider in a remote sensing system. We alluded to this idea in section 2.2 when we discussed the concept of revisit period, which refers to the length of time it takes for a satellite to complete one entire orbit cycle.
Jan 1, 2017 · Temporal resolution is defined as the amount of time needed to revisit and acquire data for the exact same location. When applied to remote sensing, this amount of time depends on the orbital characteristics of the sensor platform as well as sensor characteristics. The temporal resolution is high when the revisiting delay is low and vice-versa.
