Creating and modifying layers

You can use Builder to create layers with data you have uploaded and to make changes to layers. When you upload data, the system creates a default layer for you. You can modify this layer or create many different layers from the uploaded data file.

To modify a layer

From the Build tab, click Modify Layer.
Filter content by layers. In the filter boxes, click My Library > Layers and click View Results.

Alternatively, you can filter by Data Files. When you select a data file, you create a new layer based on that data file.
Click the Select button in the left column of the row for the layer (or data file) you want to modify. Click the Info icon to display details about a specific layer.
Click Next. The Set Filter Options page appears.
Optionally, to limit the data included with the layer, set up a filter.

To set up a filter, click the Yes button. The WHERE clause builder and Filter statement box are now available. Either use the WHERE clause builder to create a statement or type a SQL statement in the Filter statement box. This determines what information to include with the layer. For more information about SQL and WHERE clauses, see Building WHERE clauses.
Click Next. On the Classify Data page, specify how you want to classify your data, which determines how the data is represented on a map:

All values—Represents all data in this layer in the same style.
Each unique value—Represents each value in a field differently. When you select this option, the page displays a menu with fields. Select a field and click Show Values to see each value for the field. You can also provide an alias for each value.
Each range of values—Defines ranges of values of a field to represent with the same style. You can set the number of breaks for field values.

Optionally, click Customize Symbol Style. ArcWeb Services uses a default style to represent uploaded data. If you want to customize the appearance of the data, follow these steps:
- On the Modify Style page, click the Get Style button to use an existing symbol style. The Style Palette page appears.
- Select an appropriate symbol style and click OK. The style appears with its current values on the Modify Style page.
- To modify the name, scale, type, size, alignment, fill color, or outline color values, make the change in the appropriate column.
- Click OK to save the changes.

If you want to label a field in the layer, click Customize Label Style.
Select a field that you want to label. The field you select appears in the label on the map.
Customize the label.
- Click the Get Style button. The Style Palette page appears.
- Select an appropriate label style and click OK. The label style appears with its current values on the Modify Style page.
- To modify the name, scale, font, text effect, size, alignment, fill color, or outline color values, make the change in the appropriate column.
- Click OK.
  
  TIP: If you create a new label style, you can access it in the future through My Styles in the Content Library.
Click Next. The Info About This Layer page appears.
Provide essential information for your layer. An orange letter "R" indicates the required fields. Provide as much metadata information as possible.
Click Save.

A page appears with information about your layer. Click the Share to Group button to make this layer available to other users in your group. Click Notify Group to send an e-mail notification about the new data.
Click Done or Modify Another Layer to select another file to upload.
