This dialog contains advanced features available for formating this Traverse View.
Use slope distance to compute stationing instead of horizontal distance. Stations displayed in the Traverse View will be accumulated slope distance, vs accumulated horizontal distance.
Turn this on to compute the latitude and longitude based on the current survey grid. If you have not selected a grid for the survey or if the coordinates for the points in this survey are not within the range of ligitimate values for the grid, Latitude and Longitude will not be computed.
The Area computation method TPC uses does not automatically handle right-of-ways composed of two long and close parallel curves in which the segment of the outside curve extends outside of the right-of-way being computed.
If you encounter this problem, turn on the option. TPC will segment each curve in the traverse into 10 arcs for the purpose of the area computation, resulting in an accurate area computations in most circumstances.
The distance factor determines how the slope and horizontal distances in the Traverse View are related to the coordinates using the equation:
coordinate units = displayed distance units * distance factor
As an example, if you want to enter horizontal distance from a GLO plat in chains but want the coordinates to be computed in feet, enter 66.0 for the distance factor. Each horizontal distance you enter will be multiplied by 66. To re-display the distance in feet, set the distance factor to 1.
Slope and horizontal distances are stored exactly as you entered them. If you entered the data with the wrong distance factor applied, just correct the distance factor and recompute the traverse.
The status bar of the Traverse View (at the bottom of TPC desktop) displays the distance factor, along with other information, as DF=0.99999876. The Distance Factor is also included on any printouts of the traverse data.
These options set the distance factor for you. You can manually enter a distance factor or you can choose these options and any combination to establish the Distance Factor. See Coordinate Transformations.
Use the survey grid factor established for the survey. The Grid Factor relates grid and ground distances as follows: Ground Distance X Grid Factor = Grid Distance. You you use the survey grid factor here, you will enter ground distances in this traverse and TPC will compute grid coordinates.
Convert from known units like Perches, Chains and Meters to your survey's units. The unit conversion factor is multiplied by the survey's grid factor (if that option is selected) to arrive at the displayed Distance Factor.
The status bar of the Traverse View (at the bottom of TPC desktop) displays the units, along with other information, as Distance=Chains. This is also included on any printouts of the traverse data.
You can convert between Feet and Meters using International Survey Foot or U.S. Survey Foot.
