What is a Traverse?





A survey isn't just data. Or just drawings. Or just COGO. Or just any ONE thing. It's the combination of record data, field data, intersections, curves, stations, offsets, control points, side shots, closing points, areas, corner notes, cut sheets, legal descriptions, contours, geodetic positions, setbacks and the list goes on.

So how do you keep track of something as complex as a survey? Traverses!

What is a Traverse?

A traverse is a collection of points that belong together for some reason. Here are some examples:

A lot or parcel boundary, including tangents, curves and / or spirals.

A road center line and other alignments with both horizontal and vertical components

The topo shots that define any surface, like a stock pile of rock

Control points and side shots imported from a data collector

Edge of Asphalt points recalled in sequence to draw the edge of a parking lot in a drawing

A building foundation with two reference points at each corner for stakeout purposes

All the conifer shots in a site survey (all drawn with a conifer point symbol and color)

There are as many different reasons to group points together as there are survey jobs.

A Traverse can define a lot boundary or a feature line on a map or a group of points you want to download to your data collector. Traverses can be rotated and translated, copied and duplicated, turned on or off in a drawing, adjusted — and the list goes on.

Traverse Rules

A survey can have as few or as many Traverses as you want. If you are working with a subdivision, you will probably have a traverse for each lot in the subdivision. If you are staking out points on a construction project, you might have a Traverse for each building and one for miscellaneous points.

Keep in mind that you can always create additional traverses by recalling points from the survey. If you want to do something with selected points, just recall those points into a traverse and do it – at any time.

Some things you should know about Traverses

A survey can have any number of Traverses.

A Traverse can have any number of points.

When a new point is entered in a Traverse it becomes part of the survey.

Any Traverse can access (recall and change) any point in the survey.

If a point is changed in one Traverse, that change is reflected in every other Traverse that shares that point.

Traverses can be easily created from most of the views.

Traverse View

The Traverse View displays a single traverse.  You can enter, edit or recall points, change data entry formats, view and print the traverse.

You format the Traverse View to include the column sequence you want. Now enter your data and watch as TPC computes the points for you. Or recall existing points into a traverse to see their relationships (inverses). Display each point in a single row (as shown here) or use two rows per points like a conventional field book.

Name vs Description

A traverse always has a name and may also have an optional description. Both can be entered in the Traverse Manager and the traverse properties dialog.

The traverse name must be unique while the description need not be unique. Another important difference between the two is that the traverse name is used by default when you label a traverse using the Traverse Drawing Settings. If the traverse name is Lot 2, the lot label starts out as Lot 2 (you can always edit it). If you are planning on labeling traverses in this manner, consider keeping the traverse name short and using the description for additional information used to identify a traverse.
