44:005 Foundations of GIS Lab 2: Introduction to ArcCatalog Overview Part 1 Locating and previewing spatial datasets using ArcCatalog Viewing, creating and importing metadata in ArcCatalog Part 2 Creating a thematic map in ArcMap Part 1: Working with ArcCatalog ArcCatalog is the tool for browsing, organizing, distributing, and documenting an organization’s GIS data holdings. It is very much like Windows Explorer except it will not give information on when a data holding was modified. 1. Before you start the exercise, navigate to your student folder on the S drive and create a Lab 2 folder. Copy the Lab2data folder from the course Data folder to your Lab 2 folder. 2. Open the Lab2data and view the details of the files: View Details . Note that several different files are required to represent the census_2000_blocks_52 layer. 3. Start ArcCatalog: START All Programs ArcGIS ArcCatalog10 ArcCatalog has two panels… The Catalog tree on the left side of the ArcCatalog window is for browsing and organizing your GIS data. The contents of the current branch are displayed on the right side of the Catalog window. The catalog tree on the left side lists connections to local hard drives and network servers. To expand or collapse any connection, click on the + or – sign beside it or double-click its folder icon. Note that the S drive is not currently listed in the Catalog tree. To navigate to your workspace you will have to create a new connection to the S drive using the ‘ Connect to Folder ’ icon just as you do in ArcMap. 4. Click on the Connect to folder icon, click on Computer and navigate the S Drive , and then to your Lab2 folder . 044:005 Foundations of GIS Page 1 of 12

Click OK. You are now connected to the Lab 2 folder and have access to everything in the lab2 folder and any subfolders. The connection should appear in the Catalog tree . 1 The contents of each connection is listed under the Contents tab. ArcCatalog recognizes many different file types including shapefiles , coverages, raster images, TINs, geodatabases and projection files. In this lab we will be working with shapefiles (.shp). A shapefile is actually a collection of files that store the geometric (point, line, polygon) and attribute (population size for example) information of vector features such as census blocks. Note that the set of census_2000_blocks_52 files that you previously viewed through My Computer has been condensed to a single file with the .shp extension when viewed through ArcCatalog. An icon beside each shapefile indicates what kind of spatial features are stored within it. The following icons symbolize point, polygon and line features respectively. The icon next to rivers_52.shp indicates that the dataset contains line features
