GEODATABASE WORKBOOK PDF

Back to Top What is a geodatabase? Geodatabases come in many sizes; have varying numbers of users; and can scale from small, single-user databases built on files up to larger workgroup, department, and enterprise geodatabases accessed by many users. But a geodatabase is more than a collection of datasets. The term geodatabase has the following meanings in ArcGIS: The geodatabase is the native data structure for ArcGIS and is the primary data format used for editing and data management. While ArcGIS works with geographic information in numerous geographic information system GIS file formats, it is designed to work with and leverage the capabilities of the geodatabase. It is the physical store of geographic information, primarily using a DBMS or file system.

Geodatabases come in many sizes; have varying numbers of users; and can scale from small, single-user databases built on files up to larger workgroup, department, and enterprise geodatabases accessed by many users. But a geodatabase is more than a collection of datasets. The term geodatabase has the following meanings in ArcGIS: The geodatabase is the native data structure for ArcGIS and is the primary data format used for editing and data management.

While ArcGIS works with geographic information in numerous geographic information system GIS file formats, it is designed to work with and leverage the capabilities of the geodatabase. It is the physical store of geographic information, primarily using a DBMS or file system. You can access and work with this physical instance of your collection of datasets either through ArcGIS or through a database management system using SQL.

Geodatabases have a comprehensive information model for representing and managing geographic information. This information model is implemented as a series of tables holding feature classes and attributes.

In addition, advanced GIS data objects add real world behavior; rules for managing spatial integrity; and tools for working with spatial relationships of the core features and attributes. Geodatabase software logic provides the common application logic used throughout ArcGIS for accessing and working with all geographic data in a variety of files and formats. Geodatabases have a transaction model for managing GIS data workflows.

Each of these aspects of the geodatabase is described in more detail in the other topics in this section of the help.

The Quick-start tutorial provides a hands-on introduction to advanced geodatabase topics, such as relationship classes, subtypes, default values, domains, topology, geometric networks, feature-linked annotation, and dimension features in the context of editing a sample geodatabase. Creating layers for your geodatabase data The datasets are stored within a data file, which is limited in size to 2GB. Create new features and edit existing features with behaviors.

Create a file geodatabase

The Quick-start tutorial provides a hands-on introduction to advanced geodatabase topics, such as relationship classes, subtypes, default values, domains, topology, geometric networks, feature-linked annotation, and dimension features in the context of editing a sample geodatabase. The second part of the Workbook provides exercises in using the feature editing tools in ArcMap. The last part of the Workbook provides exercises that show how to create a geodatabase, load data, and implement the advanced geodatabase behavior introduced in the Quick-start tutorial. The section on editing focuses on editing simple features, and many of the exercises can be done with an ArcView TM. You will learn how to: Create geodatabase features using editing tools. Build a geodatabase from existing feature types such as shapefiles, coverage, CAD data, and more. Add behavior to your features by creating subtypes and validation rules.

Creating a file geodatabase involves creating a special file folder on disk using ArcGIS. Type a name for the file geodatabase and click Save. A file geodatabase is created in the location you specified. This allows you to share data with people who have older releases of ArcGIS, which may not be able to open newer releases of the geodatabase. Note that file geodatabase schemas have not changed since ArcGIS
