What is Arc. GIS Desktop? Arc. GIS Desktop is a GIS product created by ESRI (Environmental System Research Institute) that allows you to analyze your data and author geographic knowledge to examine relationship, test predictions, and ultimately make better decisions. It is family of three products ‐Arc. Info ‐Arc Editor ‐Arc. View That shares the same core applications, user interface, and development environment All three software products look and work the same—they differ only in how much they can do. Arc. Editor does more than Arc. View, and Arc. Info does more than Arc. Editor Each Arc. GIS Desktop product includes two applications: Arc. Map and Arc. Catalog™. Arc. Map is the application you work with to explore and analyze data and make maps. Arc. Catalog is the application you work with to manage data. Additionally, Arc. Toolbox™ is an integrated application that contains many tools for GIS tasks. You can access Arc. Toolbox from both 7 Arc. Map and Arc. Catalog

Arc. View Key Features of Arc. View: ‐ Arc. View allows performing basic visualization (map authoring), spatial query, editing and data integration, and basic modeling and analysis of your data. �Visualization: o Map authoring: e. g. predefined map templates to save time, easy to create a consistent style maps, etc. �Spatial query: o e. g. measure distances and areas, find features in the map, select data by location or attribute, switch the selection, access layer properties, etc. e. g. Proximity analysis ‐ to find out which closest services. 8

Simple feature editing and data integration: o e. g. create/edit point, line, and polygon features and attributes, integrate variety of data types including demographics, facilities, CAD drawings, imagery, web services, and multimedia. e. g. quickly make changes to several features (records) at once. �Basic modeling and analysis: o e. g. model spatial relationships, generate charts/reports from findings, etc. �Ready‐to‐Use Datasets: o e. g. ESRI Data & Maps Media Kit, which is updated annually and preconfigured to work specifically with ESRI software. �Enabled for extensions: o e. g. add even more capabilities ‐ Analysis, Productivity, and Solution‐based extensions perform extended tasks such as raster geoprocessing and three‐dimensional analysis. 9

Arc. View Components: Arc. Map, Arc. Catalog and Arc. Toolbox Arc. Map: Integrated map display, editing, and production environment. Arc. Map is used to display, query, edit, create, and analyze your geographically referenced data. Example: . Various styles for legends, scale bars, north arrows, and other map design tools are readily available in the Arc. Map environment Arc. Map compositions including charts and reports effectively communicate your message. 10

Arc. Catalog: data management application Arc. Catalog helps users to browse, search, explore, view, and manage data (with metadata creation and editing capabilities) and maps. It also helps GIS database administrators maintain spatial and tabular GIS data for use by others in their organization. Arc. Catalog interface: File/data types: 11

Arc. Toolbox: geoprocessing tool. Arc. Toolbox helps users to perform geoprocessing operations such as data conversion, overlay processing, buffering, proximity analysis and map transformation. Each tool has a menu‐driven interface with wizards or dialogs. 12

Arc. Map can be launched by clicking on the Arc. Catalog or launched from the Start menu icon on the Standard tool bar in Check off “ A new empty map” and click OK to add new map 13

Understanding Map Interface 14

Title bar and toolbars: Title bar: displays the name of the Arc. Map document. Toolbars: contains many toolbars viz. Main Menu: default tool bar with pull‐down menu that contains: File, Edit, View, Insert, Selection, Tools, Windows and Help. Click on these menus to select various options within each menu. Draw: allows drawing and editing graphics/text on the map and layout. Layout: allows display, zoom and scale layouts. Standard: allows creating a new document, opening an existing document, saving and printing a document, editing functions, adding/editing map and data, opening Arc. Catalog and Arc. Toolbox, opening Model Builder, and activating help. Tools: allows working with data view frame or work space viz. displaying, zooming, selecting, identifying, finding and measuring features and elements. Several other toolbars can be made active by right‐clicking on the Main Menu toolbar or by clicking on the pull down Main Menu/View/Toolbars… 15

Table of Contents: displays and manages (group, ungroup, activate, access layer properties, etc. ) all the layers (and its source) and symbology of the layers. Data Frame: work space that allows displaying and working with map/s. Data Frame displays maps as layers that are checked in the Table of Contents. Each displayed layer does not store the actual geographic data but it references data stored in shapefiles, geodatabases, etc. Status Bar: displays coordinates/units of the cursor in the Data View or Layout View. Table of Content Layers: A layer contains information about how to display the dataset, but not the dataset itself. Each data frame contains one or more layers. Any datasets you add to the map are represented as layers in the Table of Contents. Checking the box next to each layer will display the map elements. The order of the layers will display map elements in that order. 16

Add and remove layers To add layers for display click on Add Data icon located on the Standard Toolbar. Navigate to the shapefile that you would like to connect to. For instance: Select “few Shp files from the location” Multiple select by pressing ‘control’ key while selecting files). Highlight the file and click on Add button. Notice that all the layers are added to the Table of Contents as well as displayed (if checked) in the Data View or Layout View (whichever is active). Every time you bring in any layer, it will be displayed with random colors and can always be changed. To remove the data, select the layer then right click on the layer and click on remove. 17

View the data – examining the Attribute Table of the layer Select the layer and right click on the layer and then select open Attribute Table. Examine the table – rows corresponding columns. 18

Examine Layer Properties Right click on a layer and click on the Properties. This will display Layer Properties window. You can view, edit and change various properties of the layer. ‐General tab allows changing the name of the layer, adding description and credits, and make the layer invisible at a certain scale. ‐Source tab allows viewing the metadata and editing the data source of the layer. Selection tab allows customizing selection symbology. ‐Display tab allows changing transparency of the layer. ‐ Symbology tab allows customizing and importing symbology of the layer via Features, Categories, Quantities, Charts and Multiple Attributes. Fields tab allows displaying fields. ‐Definition Query tab allows to write scripts to query the data via Query Builder. ‐Labels tab allows displaying, changing symbology, and defining placement, scale and style of the labels. ‐Join & Relates tab allows joining and relating various datasets. ‐ HTML Popup tab allows showing the content of the layer using HTML Popup tool. 19

Understand Data View (workspace) and Layout view Data View allows displaying, editing, analyzing and working geographic data. Layout View allows preparing finished maps for printing and publishing. Three ways to switch between Data View and Layout View: 1. Click on the View tab of Main Menu toolbar and then click on Data View or Layout View. 2. Click on for Data View, and click on 3. Click on the icons for Layout View. on the Layout toolbar for Data View, Layout View and to switch between the two. Finalize and save the map On the Layout View, you can insert toolbar title, legend, scale and north arrow, via Insert tab on Main Menu, to finalize the map. Save the map by clicking on the File tab on the Main Menu toolbar. The Save dialogue box will pop up. Name the document, navigate to the location and click Save. The map will be saved as Arc. Map Document (. mxd), which will contain all the working layers and referenced data. To save the map as PDF or JPG, click on File tab on the Main Menu toolbar and click on Export Map. Navigate to the location, select the type as PDF or JPG from pull down menu, and click Save. 21

Arc. Catalog Launch Application: Arc. Catalog can be launched by clicking Start>Programs>Arc. GIS>Arc. Catalog can also be launched by clicking on the icon on the Standard tool bar in Arc. Map. Understanding the interface and its main features ‐ Toolbars ‐ Catalog Tree and Contents/Preview/Metadata window 22

Click on these menus to select various options within each menu. Standard: allows connecting to any folders on hard drive as well as folders on the network drives, disconnecting from folder, copying, pasting, deleting, viewing and searching files and folders. It also allows launching of Arc. Map, Arc Toolbox, Command Line Window, Model Builder and Help. Catalog Tree: displays all connected files and folders, and their directory tree. C/P/M Window: allows examining name and type of the file, previewing content (geography and tabular data) and viewing metadata of the file. Connect to Folder Click on the File tab on the Main Menu toolbar and select Connect to Folder or Click on the icon Navigate to the desired folder in the Connect to Folder dialog box and click OK. 23

Preview spatial data and metadata Select the shape file in the Catalog Tree to preview its spatial data and meta data. For instance, select one of. shp file (layer) in the Catalog Tree. Click on the Content tab in the C/P/M Window to view the name of the file and the type of the file. 24

Click on the Preview tab in the C/P/M Window. Click on Geography tab from the pull down menu at the bottom of the C/P/M Window to view the physical shape of the file. Click on the Table tab from the pull down menu at the bottom of the C/P/M Window to view the tabular data associated with that geography/shape. 25

Click on the Metadata tab in the C/P/M Window to view the metadata of the file. Description tab displays brief description (Abstract, Purpose, Supplemental Information, Place, Status of the Data, Time Period, etc. ) about the shape file. Spatial tab displays information about various coordinate systems used to create the shape file, coordinates, and sources of the file. Attributes tab displays features and attributes of the data associated with the shape file 26

Bring the data into Arc. Map Launch Arc. Map and display the window to full extent. Make the Arc. Catalog window smaller than Arc. Map such that Arc. Catalog window floats on the Arc. Map window. Select one layer or multiple layers by use of Shift and Control keys from the C/P/M Window. Once the layers are selected, drag and drop them in the Table of Contents window of the Arc. Map. Alternatively, you can add data from Arc. Map by clicking on the icon located on the Standard Toolbar. Source: ESRI. com 27
