A grain is a unit of mass that is traditionally used in the field of measurement for small weights. It is defined as exactly 64.79891 milligrams, which is equivalent to approximately 0.065 grams. The grain has been historically used for measuring precious metals, gemstones, and in various fields including pharmacology.
The Spatial Geodesy Research Group typically refers to a research group or academic department focusing on the study of geodesy, which is the science of measuring and understanding the Earth's geometric shape, orientation in space, and gravitational field. Geodesy is essential for applications in navigation, mapping, Earth observation, and understanding tectonic processes.
Phonomotor is a term often associated with a concept or technology related to sound and movement. However, it is commonly linked to the field of linguistics and cognitive science, particularly in studies involving speech perception, phonetics, and language acquisition. In some contexts, "phonomotor" may refer to mechanisms or processes that engage auditory stimuli (like sounds or speech) to trigger or influence motor responses.
The University of Architecture, Civil Engineering and Geodesy (UACEG) is a higher education institution located in Sofia, Bulgaria. It is well-known for its specialized programs in architecture, civil engineering, and geodesy.

The Journal of Photogrammetry, Remote Sensing and Geoinformation Science is an academic journal that focuses on the field of photogrammetry, remote sensing, and geoinformation science. It publishes research articles, reviews, and technical papers that cover a wide range of topics related to the collection, analysis, and interpretation of geospatial data obtained from various sources, including aerial and satellite imagery, LiDAR, and other remote sensing technologies.
Lower crustal flow refers to the movement of rocks in the lower part of the Earth's crust, typically occurring over geological timescales. This process is significant in the context of tectonics and geomorphology, as it plays a role in continental dynamics, mountain building, and the formation of various geological features. The lower crust is primarily composed of crystalline rocks, which, when subjected to high temperatures and pressures, can behave like viscoelastic materials.
A GPS puck is a type of GPS receiver that is often designed in a compact, puck-like shape, hence the name. These devices are used to obtain location data via GPS satellites, and they can be used for a variety of applications, including navigation, tracking, geolocation, and surveying. GPS pucks typically feature: 1. **Compact Design**: Their circular or spherical shape makes them portable and easy to mount in various settings.
The Tasseled Cap Transformation (TCT) is a mathematical technique used in remote sensing, primarily applied to multispectral satellite imagery, to enhance the interpretation of vegetation, soil, and moisture content in an area. It simplifies and summarizes multispectral data into a few key components that represent different landscape features. The transformation works by creating a new set of synthetic bands (commonly three) from the original multispectral bands.
Thermal infrared spectroscopy (TIRS) is an analytical technique used to study the infrared spectral characteristics of materials based on their thermal emissions. This technique measures the intensity of infrared radiation emitted by a sample at a specific temperature, typically in the mid-infrared range (approximately 3-30 micrometers, or 3000-30,000 nanometers).
A geodetic datum is a reference framework used in geodesy, which is the science of measuring and understanding the Earth's geometric shape, orientation in space, and gravitational field. It provides a standard for mapping and identifying locations on the Earth's surface. A geodetic datum consists of: 1. **Reference Ellipsoid**: A mathematically defined surface that approximates the shape of the Earth, allowing for the calculation of geographical coordinates (latitude and longitude).
Laser ranging satellites refer to satellites that use laser technology to measure distances between themselves and ground-based stations or other satellites. This technique, known as laser ranging or satellite laser ranging (SLR), involves emitting laser pulses from the satellite or a ground station and measuring the time it takes for the laser light to travel to the target and back.
GEOS-3, or the Geostationary Operational Environmental Satellite-3, was an early weather satellite launched by NASA in 1975. It was primarily designed to provide continuous monitoring of weather patterns and environmental conditions from a geostationary orbit. GEOS-3 was equipped with advanced imaging and sounding instruments that enabled it to capture real-time data on cloud cover, temperatures, and other atmospheric phenomena.
Geosat, or Geostationary Satellite, refers to a type of satellite that is placed in geostationary orbit, approximately 35,786 kilometers (22,236 miles) above the Earth's equator. Satellites in this orbit have a rotational period that matches the Earth's rotation, allowing them to remain fixed over a specific point on the Earth's surface.
Sfera is a series of Russian Earth observation satellites. The series is designed to enhance remote sensing capabilities, providing high-resolution imagery and data to support various applications such as agriculture, forestry, environmental monitoring, urban planning, and disaster management. The Sfera satellites are part of Russia's efforts to modernize and expand its satellite capabilities in response to both domestic needs and international demand for Earth observation data.
Retriangulation of Great Britain refers to a comprehensive geodetic surveying project initiated in the 20th century to redefine the triangulation network across Great Britain. This project aimed to improve the accuracy of measurements of the earth's surface in the United Kingdom following the original triangulation efforts conducted in the 19th century, which established a network of triangulation points used for mapping and navigation.
ISO 6709 is an international standard that specifies a representation format for geographic point locations. It defines how to express latitude and longitude coordinates in a way that is machine-readable and can be used in various applications, such as geographic information systems (GIS), mapping services, and databases. The standard provides a way to encode geographic coordinates with accompanying metadata, such as the coordinate reference system, altitude, and the precision of the coordinates.
Grid (often referred to as a spatial index) is a data structure used in Geographic Information Systems (GIS) and spatial databases to efficiently organize and retrieve spatial data based on its location. The grid spatial index divides a geographic space into a series of uniform rectangular cells or grids, each representing a specific area. It allows for faster querying and analysis of spatial data by reducing the number of comparisons that need to be made when searching for nearby points or objects.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
