| American National Standards Institute |
|
ANSI
is a private, non-profit organization that administers and coordinates
the U.S. voluntary standardization and conformity assessment system.
ANSI provides consensus standards for products, processes and services
that are at the foundation of the American economy and society.
|
| Applet |
|
A
program designed to be executed from within another application. Unlike
an application, an applet cannot be executed directly from the
operating system. A well-designed applet can be invoked from many
different operations.
|
| Application |
|
A program that performs a specific function directly for a user. Applications can make use of CGDI services.
|
| Application Program Interface (API) |
|
The
interface (calling conventions) by which an application program
accesses operating systems and other services. An API provides a means
for developing custom user interfaces. The web API provides a
programmable interface to the GeoConnections Discovery Portal.
|
| Architecture |
|
The
organizational structure and operating environment of the CGDI,
including the relationships between its parts, and the principles and
guidelines governing their design and evolution.
|
| Boolean |
|
In
programming, Boolean refers to a combinatorial system devised by George
Boole that combines propositions with the logical operators AND and OR
and IF THEN and EXCEPT and NOT.
|
| Cadastre |
|
A public record, survey, or map of the value, extent, and ownership of land as a basis of taxation.
|
| Canadian Geospatial Data Infrastructure |
|
An
Internet/web infrastructure comprised of the developments of the
federal, provincial, territorial and private sector partners who are
creating the technology, standards, access systems and protocols
necessary to harmonize all of Canada's geospatial databases, and make
them available on the Internet.
|
| Catalogue |
|
A complete list of things, usually arranged systematically. Most databases are comprised of catalogues and inventories.
|
| Client |
|
A
software component or an application that accesses a service. The Guide
to the CGDI distinguishes between a client (an inanimate part of the
process) and a user (an individual who uses a computer, program,
network or related service.)
|
| Community of Practice |
|
An
organized group of users who share common interests about a topic or
common sets of problems, or who have common needs that can be met by an
infrastructure. In this case, a community of practice has common user
requirements of the CGDI.
|
| Component |
|
Software
that packages the client or server implementation of a service and can
provide the realization of a set of interfaces. A component consists of
software code (source, binary or executable) or other equivalents such
as scripts or command files.
|
| Content Standard for Digital Geospatial |
|
The
objectives of the FGDC Content Standard for Digital Geospatial Metadata
(CSDGM) are to provide a common set of terminology and definitions for
the documentation of digital geospatial data. The standard establishes
the names of data elements and compound elements (groups of data
elements) to be used for these purposes, the definitions of these
compound elements and data elements, and information about the values
that are to be provided for the data elements.
|
| Control Widget |
|
A control widget provides the means to adjust the speed of a simulation, as well as to stop, restart and quit a simulation.
|
| Coverage |
|
A
continuous representation of a portion of the earth's surfaces. A
coverage may be a collection of features (like a vector dataset) or it
may be a raster or gridded surface representing one or more attributes.
