Traverse PC has been providing land surveying software since 1987. Here's what some of our users have to say:
'I did not realize at the time I purchased the program that I was not only buying software, but I had purchased a company that truly cares about its customers and could "look over my shoulder" to personally help me be a successful user.' Jim Sollmi, PELS, Farmington, CT
"Probably the most cost effective and efficient surveying and mapping software I have used over the past 25 years hands down!" Charles E. Porter, Kirkland, WA
"The economics are simple. Without Traverse PC our company would not have this lucrative contract." Bob Holtkamp, AB, Canada
"Traverse PC is one of the best." Gordon Bell, IN
"The last 22 years I have previewed numerous COGO software programs, but have never found anything close to Traverse PC, and with the ability to draft maps, the program is complete." Pete Ketcham, ID
"TPC Desktop is more impressive than any AutoCAD version that I have ever used." Bryan Hartsook, VA
"I really like a point based program like TPC and the friendly drawing environment that TPC has. There is no need for a lot of extensive/expensive training to do good, efficient work with TPC." Glenn Eastman, OR
"I cannot say enough about the Managers in TPC 2010... What a super great system!!! TPC will surely dominate all survey and CAD programs..." Jim Creasy, PA
"Traverse PC also includes the best, most personal, technical support we have ever seen in 26 years of surveying." Keith A. Heindel & Gary J. Ganjon, MD
"As a former CAD user, I have found the versatility and ease of use of Traverse PC to be a great benefit to my business." Dan Barry, NY
"[Traverse PC] is easier to use, less expensive, gets the job done, and comes from caring people who understand surveying and surveying needs." Joe Nachtrieb, CO
"Great stuff! You don't need to send me any other software, as I am perfectly happy with TPC and have no intentions of changing to anything else...and I have tried the other software." Randy Green, TN
"Once again you have set the standard for others to attain." George Anderson, NJ
"REALLY like everything I've seen so far... Things seem so much simpler & straight forward. Think you guys have something great here!" Cliff Tuck, AR
"[Traverse PC] is very user friendly and produces high quality survey plats." Fred Haidt, AL
"Traverse PC is the way to go for all Land Surveyors." Pete Jackson, CA
"While it has similarities to ACAD, . I would say [Traverse PC] is much more user (and surveyor) friendly." Scott Freshwaters, OR
"[Traverse PC has] cut my total production time down by making map preparation faster and easier." Sergio Sanchez, CA
"If you need surveying software, we highly recommend TPC be at the top of your list. We have found the product and support to provide us with the tools we need to improve our efficiency, accuracy and effectiveness when working for our clients." Keith A. Heindel & Gary J. Ganjon, MD
"Traverse PC is the one tool my little company has that does it all." Steve Parker, CO
"I find Traverse PC very easy and efficient to use. The applications are logical and the learning curve is very short. I would highly recommend this survey software for all land surveyors." David Holland, VA
"Yu ROCK! I am a student... ...I find the program to be very user friendly. Traverse PC is helpful with understanding how data is used to make decisions in a survey, as well as providing a visual image illustrating what the data collected is trying to show." Joel Kayser, NY

TPC Desktop 2011 - Direction Types
Coordinate directions are derived from Cartesian coordinates (Northings / Eastings) as opposed to geodetic directions which are derived from geodetic positions (Latitude / Longitude). Coordinate directions are referred to as Grid Bearing, Grid Azimuth .or just Bearing or North Az or South Az . Geodetic directions are always referred to as True Bearing or True Azimuth. TPC Desktop 2011 keeps them all straight using our new Direction types.
Even the Personal edition lets you choose between grid bearings and true bearings based on a project mapping angle or a manual mapping angle which you enter as needed. Just choose the Direction type you want in a traverse, COGO or a drawing and TPC does the rest.
A survey can have one Coordinate Reference System (CRS) that relates it's geodetic positions and rectangular coordinates. TPC computes coordinate directions by inversing between coordinates on the current CRS and applying a convergence angle (also called a mapping angle) to generate a geodetic direction. Since the CRS relates the coordinates of a point to its geodetic position, TPC can compute both a coordinate direction and a geodetic direction between any two points.
Mean Course Convergence
We're excited to offer True Bearings based on Mean Course Convergence. Whether you are doing a Direct or Inverse computation, TPC takes into account the direction at both ends of a course and means them for the computations. That means you can work seamlessly with the requirements of the PLSS or rest assured that you are extending an East-West line appropriately along a latitudinal arc. It's the rigorous solution you expect when you need true geodetic positions.
Coordinate directions use the equation:
grid direction = geodetic direction + convergence (mapping) angle
In a state plane projections, convergence angles east of the central meridian are negative, while those west of the central meridian are positive. TPC keeps track of this for you and it displays and computes directions.
