encoding
[data conversion] The recording or reformatting of data into a computer format. Data may be encoded to reduce storage, increase security, or to transfer it between systems using different file formats.
In the late 1960s, the United States Census Bureau developed Dual Independent Map Encoding (DIME), a geographic information system to handle spatial data.

[edit] Encoding
Many of the options in the JPEG standard are not commonly used, and as mentioned above, most image software uses the simpler JFIF format when creating a JPEG file, which among other things specifies the encoding method.
The encoding of data in the context of digital mapping this includes digitizing, direct recording by electronic survey instruments, and the encoding of text and attributes.
The encoding of topological relationships in such a manner that those relations are maintained even when a data layer has been physically partitioned into multiple tiles. (Compare with Seamless Database)

Data Encoding
Because the DEM data are stored in a 16-bit binary format, users must be aware of how the bytes are addressed on their computers.

LDPC Block Encoding
Low-density parity check (LDPC) encoding provides three key advantages. First, to demodulate the critical part of the L1C message with a bit error rate (BER) of [10.sup.-5] requires an Eb/[N.sub.
Run-length encoding is a format in which "along each row, only changes between attributes and the numbers of pixels of that same attribute are stored'(Clarke 1997, 83).
Run-length encoding - A method of data compression by replacing repeated sequences of values with a single value and a multiplier, e.g. 333333333333444422222 becomes (12)3(4)4(5)2 when stored as a run-length code.

run-length encodingA data compression technique for storing raster or gridded data. Run-length encoding stores data by row.
Digitize A means of converting or encoding map data that are represented in analogue form into digital information of x and y coordinates.

COGO - Coordinate Geometry: A set of procedures for encoding and manipulating bearings, distances and angles of survey data into co-ordinate data. COGO is frequently a subsystem of GIS.
Definitions: image metadata XML encoding used to describe all types of images handled by OpenGIS Framework services.
ArcInfo supports the following TIFF compression schemes: CCITT Group 4 for black-and-white data (read only); CCITT Group 3, one-dimensional encoding for black-and-white data; and PackBits. CD-ROM Compact Disk-Read Only Memory.
In this section the implications of vector and raster data models on encoding, storage, and analysis are discussed. The inherent statistical characterizations of mapped data and their implications in map analysis are described.
Individual images can be compressed either without loss using GIF, TIF, BMP and other formats, or with an "acceptable" loss using the more complex encoding provided by JPG (Joint Picture Expert Group) and similar formats.
The internal structure of the entity symbol contains the name of the entity and additional information indicating the corresponding spatial entity (point, line or polygon), a code indicating topology, and a code indicating encoding of the spatial ...
Bureau of the Census developed the TIGER (Topologically Integrated Geographic Encoding and Referencing) system.
The mapping specification for CAD drawings is a data encoding method that lets users create, manipulate, and define how CAD data is organized and attributed as GIS content. This is implemented in both ArcGIS for AutoCAD and ArcGIS 9.3 and higher.
Unicode : A character encoding scheme that is a super set of ASCII and Latin-1 with room for 65,536 characters (a 16-bit or 2-byte set).
TIGER is an acronym for topologically integrated geographic encoding and referencing file. This is a type of digital map developed by the U.S. Bureau of the Census to support the 1990 population census.
The Topologically Integrated Geographic Encoding and Referencing data format used by the U.S. Census Bureau to support census programs and surveys. It was used for the 1990 census.
The following diagram reflects the two primary spatial data encoding techniques. These are vector and raster.
Many systems of binary encoding of data and commands are proprietary and unique to particular hardware and software systems.
