The Traverse View is designed for quick entry of field data. Using the Edit Sequence specified in the Format dialog box, TPC moves from one field to another until it comes to the end of the sequence. Then it moves down one point, creating a new traverse point if necessary.
For example, if you type the edit sequence "SEF", pressing [Enter] in the Traverse View will move you from slope distance to zenith angle, horizontal angle, and then to the next point. If you want the cursor to track through the point label, add a "P" to the edit sequence ("SEFP").
You can override the edit sequence any time by using the direction keys. For instance, if you type a number then press the down arrow key, TPC will enter the number you typed and move the cursor down to the next line. The other direction keys work in a similar way.
You can edit existing data in the Traverse View at any time. Use the up, down, left and right arrow keys or your mouse to highlight the data you want to edit and enter the new data. The Traverse View will automatically recompute coordinates and inverses as appropriate.
You can enter bearings by using the quadrant number and then the bearing, where 1-NE, 2=SE, 3=SW and 4=NW. Put a period after the degrees, then type the minutes and seconds.
For example N 30°45'10" E is entered as 130.4510.
You can use existing points to enter bearings, distances and elevations as equations.
When you enter or change a number, all the corresponding computations are done automatically. For example, when you enter coordinates, the appropriate bearing and distance are recomputed. When you enter a bearing or distance, the appropriate coordinates are recomputed.
Points are recomputed from the edited point to the end of the traverse. Only points with raw data are recomputed and the computations stop with the first point that either does not have raw data or has raw data but has adjusted coordinates.
AS you edit data in the Traverse View, TPC automatically recomputes the position of the point you are editing. It also updates the position of the points that follow the point you are editing, stopping at the first point that is protected, adjusted or does not have raw data. This keeps the traverse up-to-date at all times.
There are times, however, when you will want to manually recompute the traverse. You should manually recompute when you:
When you manually recompute the traverse, TPC starts with the first point in the traverse and recomputes the position of each point in the traverse that has raw data associated with it. Adjusted points are recomputed, but protected points are not. TPC skips over points that do not have raw data and continues recomputing to the end of the traverse.
To manually recompute all the points in a traverse:
Unless you specify a traverse as a Closed Loop, Closed Point-to-Point or Open traverse, TPC uses the Closed Loop Tolerance to determine whether or not a traverse is a Closed Loop. Only Closed Loop traverses can compute an area. Closed Loop traverses can also compute their error of closure without any additional data from the user.
