2 Getting to Know ArcGIS ArcGIS is an integrated collection of GIS software products ArcGIS enables users to deploy GIS functionality wherever it is needed on the desktop or in a server; in custom applications; over the web; or in the field There are four products in the ArcGIS Desktop collection, namely: ArcReader, ArcView, ArcEditor and ArcInfo. Each version includes progressively more functionality Each version includes three components, namely: ArcMap for viewing data; ArcCatalog for working with data sources; and ArcToolbox for executing functions Source: 44

3 ArcView ArcView is a full-featured GIS software for visualizing, managing, creating, and analyzing geographic data It allows users to: Observe relationships and identify patterns in new ways View and analyze spatial data in new ways Build new geographic data sets quickly and easily Create publication-quality maps Manage all their files, database, and internet data resources from a single application Customize the user interface around tasks that need to be accomplished Source: 45

4 ArcEditor It is a complete GIS desktop system for editing and managing geographic data It is a GIS data automation and compilation product designed for construction and maintenance of geodatabase features and shapefiles It has the functionality of ArcView + comprehensive GIS editing tools ArcEditor includes tools that support metadata creation and management and geographic data exploration, analysis, and mapping It also include applications that make up the ArcGIS Desktop, i.e. ArcMap, ArcCatalog and ArcToolbox 46

5 ArcInfo is the most complete and extensible available GIS tool It includes all the functionality of ArcView and ArcEditor and adds advanced geoprocessing and data conversion capabilities Professional GIS users use ArcInfo for all aspects of data building, modeling, analysis, and map display for screen and output With ArcInfo, you can: ArcInfo Build powerful geoprocessing models for discovering relationships, analyzing data, and integrating data Perform vector overlay, proximity, and statistical analysis Convert data to and from many formats Build complex data and analysis models to automate GIS processes Publish cartographic maps using extensive display, design, printing, and data management techniques (Courtesy: ESRI) 47

6 ArcInfo - cont. There are two versions of ArcInfo in ArcGIS package: ArcInfo Desktop ArcInfo Workstation ArcInfo Desktop also include the ArcMap, ArcCatalog and ArcToolbox applications that make up the ArcGIS Desktop 48/31

7 ArcCatalog It organizes and manages all GIS information such as maps, globes, data sets, models, metadata, and services. It includes tools to: Browse and find geographic information Record, view, and manage metadata Define, export, and import geodatabase schemas and designs Search and browse GIS data on local networks and the Web Administer an ArcGIS Server Users employ ArcCatalog to organize, find, and use GIS data as well as document data holdings using standards-based metadata GIS database administrator uses ArcCatalog to define and build geodatabases 49

8 Graphical previews View data (like Windows Explorer) Tables Metadata 50

9 ArcToolbox ArcToolbox contains a comprehensive collection of geoprocessing tools for: Data management Data conversion Coverage processing Vector analysis Geocoding Statistical analysis ArcToolbox is embedded in ArcCatalog and ArcMap and is available in ArcView, ArcEditor, and ArcInfo 51

10 ArcToolbox cont. 52

11 ArcMap It is the central application in ArcGIS Desktop for all map-based tasks including cartography, map analysis, and editing It is a comprehensive map authoring application for ArcGIS Desktop It offers two types of map views, such as: 1) Geographic data view an environment where geographic layers are symbolized, analyzed, and compiled into GIS data sets - A table of contents interface organizes and controls the drawing properties of the GIS data layers in the data frame 2) Page layout view an environment where map pages contain geographic data views as well as other map elements such as scale bars, legends, north arrows, and reference maps - The page layout view is used to compose maps on pages for printing and publishing Geospatial data is displayed, viewed, queried and edited in ArcMap 53
