composed of representatives from federal and state government agencies,
academia, and the private sector. The FGDC defines spatial data metadata standards
for the United States in its Content Standard for Digital Geospatial
Metadata and manages the development of the National Spatial Data Infrastructure
(NSDI).
See Federal Geographic Data Committee.
The existing ArcObjects components that comprise the ArcGIS system.
See geodatabase.
Graphical Device Interface. A standard for representing graphical objects and
transmitting them to output devices, such as a monitor. GDI generally refers to
the Windows GDI API.
An ArcGIS Server software component that provides programmatic access to an
address locator and performs single and batch address matching. It is designed for
use in building Web services and Web applications using ArcGIS Server.
An object-oriented data model introduced by ESRI that represents geographic
features and attributes as objects and the relationships between objects but is
hosted inside a relational database management system. A geodatabase can store
objects, such as feature classes, feature datasets, nonspatial tables, and relationship
classes.
The measures and properties of points, lines, and surfaces. In a GIS, geometry is
used to represent the spatial component of geographic features. An ArcGIS
geometry class is one derived from the Geometry abstract class to represent a
shape, such as a polygon or point.
An ArcGIS tool that can create or modify spatial data, including analysis functions
(overlay, buffer, slope), data management functions (add field, copy, rename),
or data conversion functions.
The components of ArcGIS Server that host and run server objects. A GIS server
consists of a server object manager and one or more server object containers.
Globally Unique Identifier. A string used to uniquely identify an interface, class,
type library, or component category. See also class identifier.
A number system using base 16 notation.
HKEY_CLASSES_ROOT registry hive. A Windows registry root key that points
to the HKEY_LOCAL_MACHINE\Software\Classes registry key. It displays
essential information about OLE and association mappings to support drag-anddrop
operations, Windows shortcuts, and core aspects of the Windows user
interface.
A 32-bit integer returned from any member of a COM interface indicating success
or failure, often written in hexadecimal notation. An HRESULT can also
give information about the error that occurred when calling a member of a COM
interface. Visual Basic translates HRESULTS into errors; Visual C++ developers
work directly with HRESULT values.
See integrated development environment.
