IntroductionWhat is ArcGIS?

ArcGIS is a powerful technology as it helps in integrating knowledge frommultiple sources and creates crosscutting environment for collaboration. Itprovides the powerful visualization environment with strong analytic andmodeling framework that is rooted in the science of geography. It is apowerful medium for managing, visualizing and communicating about ourworld.All the GIS views are represented by three different tools:

Arc Catalog and Geodatabase: GIS is a collection of geographic

datasets.

ArcMap: GIS provides intelligent map view.

Toolbox: GIS is a set of geoprocessing tools

ArcGIS is an integrated family of GIS software products for building acomplete GIS. It consists of four primary frameworks for deploying GIS:

ArcGIS DesktopAn integrated suite of professional GIS applications

composed of three main software

BProducts: ArcView, ArcEditor, and ArcInfo

Server GISArcIMS, ArcGIS Server, and ArcGIS Image Server

Developer GISEmbeddable software components for developers toextend GIS desktops, build custom GIS applications, add custom GISservices and Web applications, and create mobile solutions

Mobile GISArcPad and ArcGIS Mobile for field computing

DesktopGIS: ArcGIS Desktop is the primary application used by GISprofessionals to compile, author, and use geographic information andknowledge. It is available at three functional levelsArcView, ArcEditor,and ArcInfo.ArcGIS Desktop includes an integrated suite of comprehensive desktopapplicationsArcMap, ArcCatalog, ArcToolbox, and ArcGlobe. Eachapplication has a rich set of GIS tools and operators.

WHAT IS ARCGIS DESKTOP?

ArcGIS Desktop is a comprehensive set of professional GIS applicationsused to solve problems;

to meet a mission; to increase efficiency;

to make better decisions; to communicate, visualize, and understand geographic information

ArcGIS Desktop refers to a suite of three integrated core applications:ArcMap, ArcCatalog, andArcToolbox.

ArcMap is used for all mapping and editing tasks, as well as map-based analysis.

ArcCatalog is the application for managing spatial data holdings, formanaging database designs, and for recording and viewing metadata.

ArcToolbox offers the tools for GIS data conversion andgeoprocessing tasks. ArcToolbox for ArcInfo comes with a complete,comprehensive set of tools (well over 150) for geoprocessing, dataconversion, map sheet management, overlay analysis, map projection,and much more; a lighter version comes with ArcView and ArcEditor.

Data Sources for ArcGIS:

B Shapefile datasets

A shapefile dataset (.shp) is stored in a folder, is composed of geographicfeatures and their attributes, and contains a single feature class. Points,lines, or polygons (areas) represent geographic features in a shapefile.Shape files are a simple, non topological format for storing the geometriclocation and attribute information of geographic features.

CAD feature datasets

The ArcGIS feature representation of a CAD file. CAD feature datasets cancontain one to five readOnly feature classes: points, polylines, polygons, multipatches, andannotation.

Raster data

Raster datasetsA collection of one or more bands of a supported raster type such as TIFF,ESRI GRID or MrSID.Raster datasets can live in a folder in a file system.

Raster catalogsRaster catalogs are a collection of raster datasets organized in a table.

Table records define the individual raster datasets included in the catalog.

Tables

Try to find some new idea from there.

2. Introduction to ArcCatalogIn this exercise, you will get familiar with the interface of the ArcCatalog.

ArcCatalog is spatial data organizer that you can use to create, model and

modify your spatial database. ArcCatalog helps you to organize and

manage these various datasets and documents in both file-based

workspaces and in geodatabases. Some idea about ArcCatalog is given in

this exercise.

The ArcCatalog application provides the necessary tools, which allow you

to

Browse and find geographic information.

Record, view, and manage metadata.

Define, export, and import geodatabase data models and datasets.

Search for and discover GIS data on local networks and the Web.

Create and manage the schemas of geodatabases.

Administer ArcSDE geodatabases.

Administer an ArcGIS server.

Hence Arc catalog has the similar performance as the window

explorer where we can manage, access, explore the existing

geographic data.

Exercise 1: Starting with ArcCatalog

Bare different views that let you change the appearance of the selected

items contents.

The Contents tab lists the items contained by the selected item in the

Catalog tree, for example, the items in a folder. When a data source such

as a shapefile is selected, the Preview tab lets you see the geographic or

attribute data it contains. The Metadata tab lets you see documentation

describing the items contents.

1. Content Tab

When you select items, such as folders or geodatabases in the Catalog tree,

the Contents tab lists the items they contain. To change the appearance of

the Contents list, use the appropriate buttons on the Standard toolbar.

To create new features use the Crete New Feature task. The Create New Feature

task works in conjunction with the target layer.

When new feature are created, they are added to the target layer. The target

layer only affects the creation of new features; you can still edit and any features

in editable layers of the map. The target layer stores new features created by the

Create New Feature task, Buffer command, Division command, Copy Parallel

command, Paste command, and other commands that create new features. You

will use the Sketch tool to create new features in the Lines layer.

3. For Target Layer, click Lines.

Distance button, the Intersection button, and the Trace button. These buttons are available by

clicking the Down arrow next to the Sketch tool button. The Arc button creates circular arc

segments for the current sketch. These arc segments are true curves with vertices at the

beginning and end of the arc segment. The Distance-Distance button finds two possible

locations given the distance from two fixed points, and you can then pick which location to

use in the sketch. The Intersection button finds the implied intersection of two lines. The tracebutton allows you to trace along or at a specified offset from selected features.
