The process of adding coordinates of locations on the earth surface, to a file of addresses. Geocoding software appends geographic coordinates to the addressed in your database. Once coordinates have been added to each address in a file, the addresses can be mapped.

Geographic coding is a process of mapping data by attaching longitude and latitude (x,y) co-ordinates based on a spatial reference. .

Process by which imagery is corrected for all source-dependent errors and geometrically transformed to the desired map projection, being resampled to a standard square pixel size.

Geocoding is the process of assigning to a street address a latitude and longitude coordinate and/or geographic codes that associate an address to census geography-such as a block group, census tract, or county.

Geocoding is the term used for determining a location along a measured network - typically this means locating a street address. Geocoding uses interpolation to locate an address - geocoded addresses are located at their theoretical location. If the address range of a street segment spans the address being geocoded, a point location will be created where that address should be. For instance, 197 will be located 97% of the way from the 100 end of the 100-199 block of Main St. (to be precise: 97 / 99 * 100 = 97.97%). Interpolation also allows for addresses that do not exist in the real world to be "found". In the example above, there may not be a property or building assigned the number 197, but the geocoding process has no way to know that and will create an address location anyway. Another limitation is the network data used - if there inaccuracies in the street network, the geocoding process will produce unexpected results.

A program that assigns a census code to a name or address, making it possible to append census data – such as income or educational level – to the file and assign cluster codes.

Associating either geographic coordinates or grid cell identifiers to data, points, lines, and shapes.

Assigning locational values (for example: latitude and longitude coordinates) to attribute data, such as an event or an address, that results in a feature being able to be mapped.

the process of translating a description of a location (such as a geoparsed street address) to a geographical coordinate, such as longitude and latitude.

Code structure used by the Geographic Information System to accumulate data by geographic locations

Procedures applied to a satellite image to generate a new image with the projection and scale properties of a map. In particular, map coordinates are associated to the center point of each element (pixel) of the resulting image.

Allocating a code to represent the spatial characteristics of an entity.

Using latitude and longitude data from the GPS receiver to determine the map location, and (with software) find the exact street address or block address.

Geographical referencing or coding of the location(s) of data items.

The process by which the geographic coordinates of a location are determined by its address, postal code, or other explicitly non-geographic descriptor.

Geocoding is also commonly known as address matching. It is the process of creating a spatial description of a place, such as a point feature from a nonspatial description of that place, like a street address. Recorded x, y coordinates of a location are cross-referencing between a standard reference grid and non-geographic data such as addresses or zip codes to accurately map that location. In order to geocode, a geocoding service must first be defined.

The technique used to geographically code and link households to small geographic units in support of data retrieval or the process of assigning a specific location to an address. ( Back to the top)

The conversion of descriptive addresses of locations to the latitude and longitude coordinate data for those locations.

Analysis of geo-demographic data such as ZIP codes, counties, regions, etc.

The process of converting tables of address data into standardized address, location, and possibly other data. See also batch geocoding.

The process of assigning a code (e.g. name, number) to a geographic feature (see reverse geocoding).

Process of assigning geographic locations (including addresses) to objects relative to a standard reference grid (co-ordinate system).

An image is geocoded if a precise algorithm for determining the earth-location of each point in the image is defined.

The process of appending latitude and longitude coordinates to a database record so it can be properly placed on a geographical map.

In spatial databases, a coding process wherein a digital map feature is assigned an attribute to serve as a unique ID (tract number, node number) or classification (soil type, zoning category). In polygon processing, the polygon boundary that contains the coordinate pair of a data item (text label) is assigned the value of that data item as geocode. Geocodes are also referenced as "location identifiers".

Geocoding is the process of assigning geographic identifiers (e.g., codes or geographic coordinates expressed as latitude-longitude) to map features and other data records, such as street addresses. You can also geocode media, for example where a picture was taken, IP Addresses, and anything that has a geographic component. With geographic coordinates, the features can then be mapped and entered into Geographic Information Systems.
