Sketch construction tools in ArcMap will allow you to quickly and accurately edit street rights-of-way. 2 EDITING IN ARCMAP ch1.p65 2 01/24/2001, 3:51 PM Universal data editor ArcMap lets you edit shapefiles, coverages, and geodatabases in their native data formats. Also, you can edit an entire folder of data at once. Pick the folder of data that you want to edit when you start editing in ArcMap. INTRODUCTION 3 ch1.p65 3 01/10/2001, 9:58 AM Editing in data view and layout view ArcMap provides two different ways to view a map: data view and layout view. Each view lets you look at and interact with the map in a different way. Data view hides all of the map elements on the layout such as titles, North arrows, and scale bars. In layout view, youll see a virtual page upon which you can place and arrange map elements. You can edit your geographic data in either data view or layout view. Maximize the display of geographic information when editing using data view. When you are preparing a map, you can edit features directly using layout view. 4 EDITING IN ARCMAP ch1.p65 4 01/10/2001, 10:00 AM Context menus and shortcut keys for increased productivity ArcMap contains numerous context menus and shortcut keys to help you create and edit features quickly. Use the sketch tool context menu and shortcut keys to access advanced feature creation tools. INTRODUCTION 5 ch1.p65 5 01/10/2001, 10:02 AM Multiuser editing with version management and conflict detection If you have several users that need to edit the same data at the same time, ArcMap can help you manage versions of your ArcSDE geodatabase. Sophisticated version management tools in ArcMap will help you maintain a multiuser editing environment. 6 EDITING IN ARCMAP ch1.p65 6 01/10/2001, 10:03 AM Editing in projected space If youve collected data from a variety of sources, chances are that not all layers contain the same coordinate system information. Using ArcMap, you can set the coordinate system for a data frame. As you add layers to your map, they are automatically transformed to that projection. That means that you can edit the shapes and attributes of a layer regardless of the coordinate system it was stored in. ArcMap has “project-on-the-fly” capabilities that let you edit layers in the coordinate system that is most important to you without having to transform your data. INTRODUCTION 7 ch1.p65 7 01/10/2001, 10:04 AM Tips on learning how to edit in ArcMap If youre new to GIS, remember that you dont have to learn About this book everything about editing in ArcMap to get immediate results.
