There are times when it is easier to survey a series of line features as one by surveying sections across the features, for example when surveying multiple railway tracks. The surveyed feature will then be a zigzag that will move back and forth across the line features. The Zigzag option is a pop-up menu that allows you options to split the single surveyed feature into a series of feature strings. The pop-up menu is shown below and there are two types of zigzag feature.
Reverse - is where the surveyed feature moves back and forth across the multiple strings. Therefore, the features will be surveyed in the order 1234, then 4321, then 1234 and so on.
Sequence - is where the surveyed feature always starts at the same feature. Therefore, the features will be surveyed in the order 1234, then 1234, then 1234 and so on.
Whichever option you select, you will be asked to indicate the surveyed feature and to enter the number of strings in which the surveyed feature is to be split. The same code as the surveyed feature will be used for all strings and the first point on each feature will have a new feature comma code added to its code.
