ArcCatalog
|
|
Keywords:
GIS, ArcCatalog
|
Geographic information exists in many forms, including relational databases, files, ArcGIS documents, and remote GIS web services. ArcGIS applications work together to allow you to work with geographic information and other ancillary data that exist in various data sources, including datasets, relational databases, and many file types and schemas.
ArcCatalog helps GIS users by providing an integrated and unified view of all the data files, databases, and ArcGIS documents available to ArcGIS users. Unlike other data (a photo or Word document), geographic datasets often consist of a set of files, rather than a single file. When listed in Windows Explorer, the datasets appear as a list of system folders and files, whereas ArcCatalog displays and manages the datasets as single entities.

ArcGIS
|
|
Keywords:
GIS, ESRI, ArcGIS
|
ArcGIS is the name of a group of geographic information system software product lines produced by ESRI.
Prior to the ArcGIS suite, ESRI had focused its software development on the command line Arc/INFO workstation program and several Graphical User Interface-based products such as the ArcView GIS 3.x desktop program. Other ESRI products included MapObjects, a programming library for developers, and ArcSDE as a relational database management system. The various products had branched out into multiple source trees and did not integrate well with one another. In January 1997, ESRI decided to revamp its GIS software platform, creating a single integrated software architecture.

ArcGIS Engine Runtime
|
|
Keywords:
GIS, ArcGIS Engine Runtime
|
The final component of ArcGIS Engine is the ArcGIS Engine Runtime license and its extensions. All applications built with the ArcGIS Engine Developer Kit require ArcGIS Engine Runtime, with the appropriate license, to execute successfully. ArcGIS Engine Runtime is the platform on which ArcGIS Desktop is built; this allows users of ArcGIS Desktop applications to execute custom applications based on ArcGIS Engine, if permitted by the ArcGIS Engine application developer.

ArcIMS
|
|
Keywords:
GIS, ArcIMS
|
ArcIMS (standing for Arc Internet Map Server) is a Web Map Server produced by ESRI. It is a GIS that is designed to serve maps across the Internet. Sometimes these maps are just static images allowing simple panning and zooming, while others are more complex pages. Examples of interactive maps served with ArcIMS include maps with layers that can be turned on and off, or with features containing attributes that can be queried. A visitor to a site driven by ArcIMS needs nothing more than a web browser: the GIS and database are maintained on the server side.
Using ArcIMS, city and local governments, businesses, and other organizations worldwide share geospatial information both internally and to the public.

ArcMap
|
|
Keywords:
GIS, ArcMap
|
ArcMap is a component of ESRI's ArcGIS Geographical Information System (GIS). It is developed as client software specifically for the Microsoft Windows environment, to enable more intuitive processing and presentation of ArcGIS data. It does not currently contain as much functionality as its sister program ArcInfo.

Geodatabase
|
|
Keywords:
GIS, Geodatabase
|
The geodatabase provides the data storage and data management framework for ArcGIS. Each geodatabase is a collection of various geographic datasets that reside in a file system folder, a Microsoft® Access™ database, or a relational database management system such as Oracle®, Microsoft® SQL Server®, PostgreSQL®, Informix® or IBM® DB2.
A key geodatabase concept is the dataset. It is the primary mechanism used to organize and use geographic information in ArcGIS. The geodatabase contains three primary dataset types: Feature Classes, Raster Datasets, and Tables.

|
Keywords:
GIS, shapefile
|
The ESRI Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. A "shapefile" commonly refers to a collection of files with ".shp", ".shx", ".dbf", and other extensions on a common prefix name (e.g., "lakes.*"). Shapefiles are simple because they store primitive geometrical data types of points, lines, and polygons.
