Layer files Saving a layer file Group Layer Files Adding a layer file into

Importing Layer files Selecting a layer file to apply to the current feature layer The Import Symbology window where *. lyr and *. avl files can be applied to the current feature layer, or a legend from another feature layer in the project can be copied.

Storing annotation Store annotation in the map document Store annotation as a feature class in geodatabase Store feature-linked annotation in geodatabase Annotation feature class in Arc. Catalog Copyright © 2014 Natural Environmental Research Council (NERC) 23

Chapter Summary You have now learnt to: • Symbolise data to make it more meaningful • Save, reuse and share symbology • Apply a standard symbolisation using stylesheets • Use layer files to save symbolisation • Recognise the differences between labelling and annotation • Place labels and set their scales • Convert labels to annotation Copyright © 2012 Natural Environmental Research Council (NERC) 24
