Think of a survey as a project or job. A typical survey has coordinate points, traverses, drawings, surfaces and reports that combine to form the survey.
TPC works with one survey at a time - the current survey. You can create a new survey or open an existing survey to work on it. When you are finished, you save the survey back to the survey file.
TPC puts an entire survey in a single file with a .TRV file extension. Keeping everything in one file makes it easy to organize and manage your surveys.
The TPC Survey System is an innovative and efficient way of managing your surveys. It all starts with the TPC Desktop, where you'll find everything in one place. You'll use the views to access the parts of the survey you want, when you want them using our Obvious Navigation.
Points - points hold the coordinates in the survey and identify them by point label and description. In TPC, you manage points in the Points Manager.
Traverses - a traverse is any sequence of points that belongs together. Traverses are the absolute best way to organize your survey points. You can open a traverse in the Traverse View to edit it's data, the Closure View to check its closure or adjust its coordinates or the Vertical Curve View to refine its vertical alignment. You manage traverses in the Traverses Manager.
Record Data - record data describes existing features like lots, easements, boundaries and right-of-ways. You typically enter reocrd data into a traverse that computes the points and draws the feature as you enter the data.
Field Data - you can enter conventional data like angles and distances or GPS data like latitude and longitude. You can also import this data from an electronic data collector and recreate the data as if you had entered it manually.
Drawings - a survey can have as many drawings as you need. Drawings include any tagged traverses and surfaces, smart drawing objects like legends and line tables plus anything you draw manually. You open existing drawing or create new ones in the Drawings Manager and work on the current drawing in the Drawing View.
Surfaces - a survey can have any number of surfaces which you can tag to include in a drawing just like traverses. You manage surfaces in the Surfaces Manager.
COGO - TPC includes all the standard COGO routines like intersections, rotating and translation plus others like offsets to an alignment. COGO routines can modify existing survey points, create new one, create traverses to help organize the points they create and provide information about the survey.
Reports - TPC includes many reports like the Legal Description writer, Least Squares Analysis, offsets to a line and more. These are created in the Report Veiw where you can edit the information like you would in any word processor.
TPC stores all the information for a survey in a single survey file with the TRV extension. See Working with Surveys.
TPC lets you export data in a number of different file formats and directly to some devices. You can also import data from a number of devices directly or from a file using one of the existing filters.
TPC ships with sample survey that help you learn how to organize your surveys. These are real surveys. Open them to get a feel for how to use traverses and drawings.
