Modify Route ID Padding (Location Referencing)

Location Referencing ライセンスで利用可能です。

サマリー

Modifies the padding, null, and length properties for fields that are part of a multifield route ID.

A route ID is configured with three fields: RouteType, RouteNumber, and RampNumber. Sample padding and null settings for the three fields are shown below.

• RouteType is a text field with a length of 3. The maximum number of characters that will be entered is three; however, some routes may have one or two characters entered for this field. A hyphen is used as a padding character to the right.
• RouteNumber is a short field type. The field will have values ranging from 0 to 99999; 0 is used as a padding character to the left.
• RampNumber is a text field with a length of 7; however, some routes will not have a value for this field and need to be left blank. An underscore is used as a padding character to the left and right.

使用法

• Each field in the route ID can have its maximum length shortened; be variable or fixed length; or have padding characters added to the left, right, or both left and right sides, as well as have padding added to an empty field. Additionally, a null value can be used for one or more of the fields in a concatenated route ID.

• The route ID for each record will be stored with padding and null values included. Each individual field used as part of the concatenated route ID will be stored without any padding character.

• Padding and null settings can be changed once the network is created. Any routes loaded and created before changing these settings remain saved as is in the database. Any route loaded and created after changing the settings uses these updated settings while saving in the database.

• Changing the length only changes the maximum number of characters that ArcGIS Roads and Highways expects for each field as part of a route in the network. Your data should still be modeled in your geodatabase with the route ID field length being the sum of the lengths of the fields composing the concatenated route ID.

• The Allow Null Values check box must be checked if the Pad if Null check box has been checked.

• If you allow null values in a field, all fields to the right of that field must also allow null values. However, if the Pad If No Value Provided check box is checked, fields to the right do not have to allow null values.

• A number sign (#) is not supported as a padding character.
