Modifying shapefile attributes

When you upload shapefiles to Esri Redistricting, you can modify the attributes of the shapefile to change the appearance on the map. When shapefiles are uploaded, the Map Contents panel automatically displays two layers for the shapefile. One layer contains the shapefile and another layer for the label. A Tools tab displays the necessary tools to modify attributes for these layers.

In this topic, you will learn how to modify the following shapefile and label attributes for the following:

• Transparancy
• Shapefile symbology
• Label symbology
• Scale dependency

Note:

The following steps assume you have uploaded a shapefile to your Esri Redistricting session. See Adding map contents to Esri Redistricting from a shapefile.

By default, all uploaded shapefiles are visible at all scales. However, if you upload many shapefiles, the map's performance may be hindered as each shapefile is rendered on the map.
