![]() ![]() For example, while you can view coverages in ArcMap, you can only edit them in ArcInfo Workstation. Some types of data, such as CAD drawings or coverages, can be viewed but not edited inside ArcMap and must be edited in the data's native application. When users are ready to apply their edits, they merge their changes through a process of reconciling edits, resolving conflicts, and posting their changes to the parent version of a database. Versions allow multiple users in a multiuser geodatabase to edit the same data without applying feature locks or duplicating data. ![]() When you are working with data in a database, making edits and saving them are transactions against the database. When you save edits, you write them to the data source, or a database. Just saving a map document does not save the edits to the features-you need to specifically save the edits in your edit session. You can also quit an edit session without saving your changes. However, editing in layout view is useful when you want to make minor additions to your map in the context of your map layout.Įdits are temporary until you choose to save and apply them permanently to your data. You can also edit in layout view, although editing is typically easier and more accurate in data view. Most of the time you edit data in data view, since it shows only the data in your map and hides the layout elements. If you right-click a layer in the table of contents, you automatically start an edit session on the entire workspace containing that layer. If you use the Editor menu to start editing on a data frame that contains data from multiple workspaces, you are prompted to choose the workspace to edit. There are two ways to start an edit session: by clicking the Editor menu on the Editor toolbar or by right-clicking a layer in the table of contents. Although you can edit data in different coordinate systems, it is generally best if all the data you plan to edit together has the same coordinate system as the data frame. If you have more than one data frame in your map, you can only edit the layers in one data frame-even if all data is in the same workspace. Editing applies to a single workspace in a single ArcMap data frame, where a workspace is a geodatabase or a folder of shapefiles. When you want to edit, you need to start an edit session, which you end when you're done. During an edit session, you can create or modify vector features or tabular attribute information.
