The Left and Right Odd/Even Indicator fields are used to specify whether the sides of the street segment contain odd or even address ranges. Although these indicators are not required for creating a User Dictionary, it is important to use the Odd/Even Indicators when your data contains odd/even address numbers.
When the Odd/Even Indicator is specified, but is inconsistent with address numbers, the indicator is set to Both.
When the Odd/Even Indicator is not specified and both Start Address and End Address have values, the indicator is set to Both, unless the start and end address numbers are the same number. In that case, the indicator is set to Odd if the address numbers are odd, and set to Even if the address numbers are even.
When the Odd/Even Indicator is not specified and both Start Address and End Address have values, the indicator is set to Both (odd and even).
The following table describes the optional input fields.
