Term | Definition |
AJAX | Asynchronous JavaScript And XML |
API | Application Programming Interface |
application programming interface (API) | Functions that one application exposes to another |
asynchronous | Two-way communication in which parties respond at their convenience, such as a telephone conversation. Not synchronous |
bounding box | A rectangular geographical area, defined by the latitude and longitude coordinates at two opposite corners |
CBD | Central Business District |
EMS | Enhanced Mapping Service |
Enhanced Mapping Service (EMS) | The name used for the Whereis® API internally, and applied to its JavaScript namespace |
extent | Geographical area, synonymous with "bounding box" |
geocode | Return the latitude and longitude coordinates that correspond to a given address. The term is also used to denote a datatype that fully defines a location, in terms of its latitude and longitude, street address, granularity, and its border with other locations of a similar type. |
geodetic datum | Mathematical definition of the Earth's shape |
geometry | Shapes and points that can be described on a map, such as the points that make up the line of a route |
granularity | Describes a location's scale, in particular whether a set of latitude and longitude coordinates should be taken to apply to a property, street, intersection, suburb, state or region |
id | identifier |
intersection | Street that intersects with another street |
LGA | Local Government Area, such as "Boddington Council", "Hobsons Bay Council", and so on. |
JavaScript object notation (JSON) | A lightweight data transmission format |
JSON | JavaScript Object Notation |
OpenLayers | An open source, object-oriented, JavaScript library that facilitates the display of maps and map data on a web page |
pan | Change the position of an image without changing the size or position of the frame you're viewing it through |
POI | Point Of Interest |
point of interest (POI) | Place, service, or product that can be represented by an icon on a map, defined by the icon's image and the latitude and longitude coordinates at its rendered position |
rank | Calculate an order for sets of longitude and latitude coordinates according to their distance from a reference point |
| resolution | A measure of scale, given in degrees longitude per pixel. |
reverse geocode | Return the address or addresses that correspond to a given set of latitude and longitude coordinates. A reverse geocode operation returns a geocode object |
route | Travel directions from a start point to an end point, which may pass through one or more waypoints |
small scale | Map scaled so that real-world entities look small. A small scale map depicts a wide area without much detail |
uniform resource locator (URL) | The address of a document, image, or other entity. An HTTP URL is a web address, which you could type into your browser address bar in order to return the entity itself |
URL | Uniform Resource Locator |
viewport | Precisely defines the bounding box of a viewable map, including real-world distances, and pixel resolution |
waypoint | A geographical position, defined by its latitude and longitude, through which a route must pass |
WGS84 | World Geodetic System 1984 |
World Geodetic System 1984 (WGS84) | One of several geodetic datums that describes the shape of the Earth. WGS84 is the standard currently used for global positioning systems, enabling international agreement as to the precise location on the Earth represented by any particular set of longitude and latitude coordinates |
zoom | Change the scale of an image without changing the size of the frame you're viewing it through. Zoom in to view a larger scale map of a smaller area. Zoom out to view a smaller scale map of a larger area |
z-order | Numbered order, from front-most to back-most or vice versa, in which a graphical system should render overlapping two-dimensional objects |
