Create labels

Maps can display large amounts of geographic data in layers that generally overlap. The way you draw your layers helps to describe and identify features, but sometimes you need more than just a particular symbol or color or to convey what you want to say with your map. This is when labeling features can help. Labels are short pieces of text that describe features in a layer and help your audience understand what they are looking at.

The text for a label is usually derived from the layer attributes. To display labels for a layer, select one or more attributes you want to show, for example, the name or type of feature. The map viewer automatically places labels on the map on or near the features they describe. You can control the text size, color, and style to help differentiate labels from different layers.

The map viewer places as many labels on the map as possible without overlapping them. Thus, in areas where features are tightly clustered, some features may not get labeled. As you zoom in to an area, more labels will dynamically appear. Labeling priority follows the layer order in your map from top to bottom. Layers at the top get labeled first and thus, will have the most labels. There is no guarantee that you’ll get the labels you want positioned exactly where you want them. Thus, dynamic labeling is best suited for maps where you don’t need precise control and only want to label a few layers.

You can create labels for features in hosted feature layers, ArcGIS Server feature service layers, individual layers from ArcGIS Server map service layers, CSV on the web, and layers from files.

  1. Verify that you are signed in and have privileges to create content.
  2. Open the map in the map viewer, click Details, and click Contents.
  3. Browse to the sublayer that contains the features you want to label.
  4. Click the arrow to the right of the layer name and click Create Labels.
  5. Create the labels by adding the following information:
    • Check the box to label features.
    • Enter text for the label. Click [+] and select a field value to use as your label. You can also type static text instead of or in addition to the field value.
    • If you want, change the size, style, and color of the text.
    • Choose how to align the label relative to the feature.
  6. Click OK when you are finished creating your labels.
  7. Click the arrow to the right of the layer name and click Save Layer to save the configuration as a property of the item. You can only save item properties if you own the layer or if you save it as a new item.
  8. If you have more than one layer with labels, you can organize the layers to affect how the labels are displayed. The layer at the top of your map contents is labeled first and has the most labels. The layer under your map contents is labeled next and has fewer labels, and so on.
  9. Click Save from the top of the map viewer to save the labels to the map.
  10. To remove or change the labels, click the arrow to the right of the layer name and click Manage Labels.
