1 Introduction to ArcCatalog

2 Introduction To Arc Catalog ArcCatalog is a data- centric GUI tool used for managing spatial data

3 With ArcCatalog you can. Inspect properties and attributes of data Preview and explore data contents Evaluate quality and suitability of data Create, move, copy, delete, organize, and rename Review, update and define metadata Import, export, convert Define rules and behavior

4 ArcCatalog Gives You. Direct access to all your data live. Connections to any local or network disks. Connections to local or remote folders. Connections to relational databases via ArcSDE MS SQL Server, Oracle, DB2, Sybase, etc. OLE DB MS Access (jet), Oracle, MS SQL Server, etc. Typically OLE DB can retrieve only non-spatial data Personal geodatabases MS Access (jet)

5 ArcCatalog Is Better Equipped to Allow GIS Analysts To Manage the GIS data explosion Control consistency and quality of data Maintain inventory of data holdings Expose incomplete metadata Identify redundant data

6 ArcCatalog ArcCatalog Is the Principal User Interface Used to Define and Manage the Geodatabase

7 What is a Geodatabase? A new type of geographic data format (GDF) for ArcInfo 8. Based on Object-Oriented Model Users can add behavior, properties, rules and relationships to data Implemented as extension to standard relational database technology Supports topologically integrated feature classes

8 Geographic Feature Data Formats Shapefile introduced with ArcView Also georelational data model nontopological vector data format. Very prolific format much GIS data in Shapefile format. Simpler than coverages than because they do not store topological associations among different features and feature classes. Limited analysis capabilities due to lack of topology Geodatabase introduced in ArcInfo. 8 Object-oriented model can characterize features more naturally by defining object types, topological, spatial and general relationships, and interactions. Geodatabase features can be stored in a single database. Create custom features in addition to points, lines, polygons Brings physical model closer to logical model.

9 Supported Data Types supports four representations of geographic data. Vector data for representing features. Raster data for images, grids, and surfaces. Triangulated irregular networks (TINS) for surfaces. Tabular data. Locators and addresses for finding a geographic position from an address. Locators apply national postal conventions to convert an address to a position.

10 ArcCatalog and Metadata Metadata is primarily viewed and edited in ArcCatalog. ArcCatalog allows metadata to be easily created, stored, and accessed for all data types supported by ArcInfo 8.0 using open, flexible, industry standard technology. AI8 has out-of-the-box support for the federal geographic data committee (FGDC) metadata content standard, ArcCatalog has a built-in and easily accessible fullfeatured metadata editor. AI8 automatically stores metadata with the data so that it also travels when the data is moved, distributed, exported, or renamed, including attached documents.

11 ArcCatalog and Metadata Bottom line: metadata editor is easy to use. Result = more organized and accurate data.

12 Creating and Editing Metadata Choose dataset and click the metadata tab Metadata is automatically created if it doesn t exist This can be turned on/off Some metadata is automatically obtained ( harvested ( from the data You can control frequency of metadata harvesting Automatic time interval Manually Any file type can be added as an attachment to the metadata to extend metadata information

13 ArcCatalog Metadata Editor

14 ArcCatalog From ArcCatalog you can add and edit the properties of fields in tables, shapefiles and feature classes by right clicking on the object and going to properties.
