Coordinate systems created with either of these methods will be displayed in the Custom folder.Ĭhanging the coordinate system of a data frame doesn't alter theĬoordinate systems of the source data in the data frame. You can also modify parameters of an existing coordinate system by right-clicking it and selecting Modify Item.

You can create a new coordinate system by clicking the Add Coordinate System drop-down menu, and selecting New. When using the filter options to reduce the number of available coordinate systems, only the folders containing the matching coordinate systems will appear. The String Filter filters the list of coordinate systems based on folder names, coordinate system names, or well-known ids (WKID). The Spatial Filter filters the list of coordinate systems based on the extent provided, whether it be the Current Visible Extent, an Outline of Features, an Outline of Selected Graphics, or a Custom Extent. You can filter the coordinate systems presented in the dialog box by performing a Spatial Filter, a String Filter, or a combination of the two. Click the Coordinate System tab and navigate to the desired coordinate system for your map display.Right-click the data frame name and choose Properties to bring up the Data Frame Properties dialog box.To end your editing session, click Stop Editingfrom the Editor menu. To set the coordinate system of a data frame, you must notĬurrently be editing. Is using, you should use the Define Projection tool in ArcToolbox to assign Generally, if you have a layer whose dataset does not haveĪ coordinate system defined and you know which coordinate system it In this case, you'll have to supply the necessary coordinate system The data frame's coordinate system as long as the data source's coordinate system is defined.ĪrcMap will be unable to project the data in each layer and display it correctly. The first layer added to an emptyĭata frame sets the coordinate system for the data frame, but youĪs you add subsequent layers, they are automatically displayed using When ArcMap is started with a new, empty map, the coordinate systemįor the default data frame is not defined. Theĭata frame's coordinate system need not be the same as the data youĪre using, although if ArcMap has to project your data on the fly, It determines the map projection for the map display in the data frame. To display your data correctly, each data frame uses Changing the data frame's coordinate system.
