Z-order curveIn mathematical analysis and computer science, functions which are Z-order, Lebesgue curve, Morton space-filling curve, Morton order or Morton code map multidimensional data to one dimension while preserving locality of the data points (two points close together in multidimensions with high probability lie also close together in Morton order).GeocodeA geocode or geographic identifier (sometimes shortened as geo ID) is a code or unique identifier that represents a geographic entity (location or object), as distinguished from other entities in the same geocode system. In general, a geocode is a human-readable and short identifier. The ISO 19112 standard also admits long labels as geocodes. Geocodes are mainly used (in general as an atomic data type) for labelling, data integrity, geotagging and spatial indexing.
64-bit computingIn computer architecture, 64-bitintegers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses.
Internet forumAn Internet forum, or message board, is an online discussion platform where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible. The name comes from the forums of Ancient Rome.Base32Base32 is binary-to-text encoding based on the base-32 numeral system. It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (25). Since base32 is not very widely adopted, the question of notation i.e. which characters to use to represent the 32 digits is not as settled as in the case of more well-known numeral systems (such as hexadecimal) even though RFCs and unofficial and de facto standards exist.

EmailElectronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving digital messages using electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence e- + mail).
Space-filling curveIn mathematical analysis, a space-filling curve is a curve whose range reaches every point in a higher dimensional region, typically the unit square (or more generally an n-dimensional unit hypercube). Because Giuseppe Peano (1858–1932) was the first to discover one, space-filling curves in the 2-dimensional plane are sometimes called Peano curves, but that phrase also refers to the Peano curve, the specific example of a space-filling curve found by Peano.Grid (spatial index)In the context of a spatial index, a grid or mesh is a regular tessellation of a manifold or 2-D surface that divides it into a series of contiguous cells, which can then be assigned unique identifiers and used for spatial indexing purposes. A wide variety of such grids have been proposed or are currently in use, including grids based on "square" or "rectangular" cells, triangular grids or meshes, hexagonal grids, and grids based on diamond-shaped cells.
Public domainThe public domain (PD) consists of all creative work to which no exclusiveintellectual property rights apply. Those rights may have expired, be forfeit, waived or may be inapplicable. Because no one holds the exclusive rights, anyone can legally use or reference those works without permission.
URLA uniform resource locator (URL), colloquially known as a web address, is a reference to a resource on the World Wide Web. A URL specifies the location of a resource on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably.Human-readable medium and dataIn computing, a human-readable medium or human-readable format is any encoding of data or information that can be naturally read by humans, resulting in human-readable data. It is often encoded as ASCII or Unicode text, rather than as binary data. In most contexts, the alternative to a human-readable representation is a machine-readable format or medium of data primarily designed for reading by electronic, mechanical or optical devices, or computers.*As an Amazon Associate I earn from qualifying purchases.
