You must comply with the following organizational rules when creating your Landmark Auxiliary file.
-
Use semicolons in the first column to indicate a row is a comment, not a data record; GeoTAX ignores rows that begin with a semicolon.
-
Order the records within the file by descending ZIP Code then descending street name for optimal performance.
-
All records must represent one or both sides of a street.
-
All records must represent segments that are straight lines. Records cannot represent a non-straight segment.
-
If house numbers are present in the record, the house number range must be valid according to USPS rules documented in Publication 28.
-
The numeric fields, such as ZIP Codes, must contain all numbers.
-
Latitude and longitude values must be in millionths of decimal degrees.
-
Records cannot contain PO Box addresses.
