John Balcom: Best Fit Curve
Last month, I wrote about the new Fit Horizontal Line routine in TPC 2016 R1 (which will soon be released to TPC Connection members only). This month I want to tell you about the Fit Horizontal Curve routine.
Traverse PC has had a best fit curve routine almost since day one. We kept that functionality in the Average Between First and Last option and rounded it out with the Least Squares option along withSummary and Undo.
The Least Squares option is the one you want to use if you don’t know exactly where the PC and PT are. Let TPC fit the curve, then simply extend or contract the curve end points as needed to match the rest of the survey.

Mark Lull: Coordinate Reference Systems
Traverse PC’s Premium and Professional Editions have included various Coordinate Reference Systems (CRS) for many years. In addition you could always add or edit CRSs on your own or with our help. In TPC Desktop 2016 R1 (coming soon to TPC Connection members only), working with CRSs is getting a lot easier. Check out the video and Oliver’s section of our February eNewsletter to see for yourself.
The Coordinate Reference System tab of the Survey Information dialog box now provides a lot more information about the CRS you are working in. In addition, you can click the Open CRS folder button to easily add a new CRS or edit an existing one.
We are always on the lookout for any CRS that our users may need. We just added Indiana (InGCS) and Iowa (IaRCS) to the list in TPC Desktop 2016 R1 to round out our state CRS list. If you know of any others that we should support, please email the information to me.
As you can see in the example shown here, the CRS file can contain several different types of records (Description, Ellipse, FileUnits, SurveyUnits, Horizontal Datum and more). All of the different record types are defined with examples in the SyntaxCRS.txt file which is stored in the same folder. This makes it very easy for users to edit an existing CRS or create a new one to meet their needs.
If you choose to, you can comment out the Zones you never need so they don’t even show up in the Zone list in TPC. (TPC doesn’t read any lines that start with the # sign.) You can also move CRS files out of the folder if you never use them. These techniques simplify your choices within the program but allow you to get them back later if necessary.
The new CRS interface is intended to make things easier for the user while providing maximum flexibility. Isn’t that what it’s all about? Ease of use, flexibility, control, precision – Innovation and Elegance – That’s Traverse PC.

Oliver Bochsler: Sending Large Files
Most email systems have limits on how large the emails you send and receive can be. This includes not only the email message but all attachments to the email. 10 MB is a common limit. In today’s world of large image files and, in some cases program and system dumps, these limits can be a problem.
Traverse PC occasionally uses program dumps to assist our software development team in tracking down elusive issues that can’t be identified in any other way. These program dump sizes usually exceed the email limit sizes and they can’t be reduced much by compressing them into zip files. We had to find another way to be able to retrieve these large files.
What we found is WeTransfer. WeTransfer allows any user to send files up to a total of 2 GB to anyone else with an email address. If you need to send more than 2 GB of files, you can do multiple batches of files or upgrade to WeTransfer’s “Plus” account which lets you send up to 20 GB of files at a time.
So what’s the bottom line here? If you need to send large batches of family photos to your friends and relatives or if you need to send program dumps to Traverse PC, WeTransfer can get the job done for you, and for us.

Eric Tanikawa: We’ve Got Your Back!
Since 1987, Traverse PC users have been going strong with their perpetual licenses! Occasionally, we hear from someone who is still using version 2.53! The COGO functions, Closure routines and many other features are still beneficial for their survey work. Most of the time, they update to the latest version of Traverse PC. Those who like our technical support, training and program updates continue to choose the TPC Connection membership.
A perpetual license allows the user to use the software for as long as they continue to comply with the terms of the license agreement. The license is paid for once and does not need to be renewed. Our users always have the option to purchase updates (no matter how long it has been since they last updated) or the annual TPC Connection membership, which includes training, support, updates and more.
Some companies force their users to convert to an annual license subscription that will only allow the customer to use the software for one year. After the one year period ends, the software no longer functions unless a new license is purchased. And what if you don’t “take advantage” of their offer? You’re just out of luck.
Here at TPC, we believe that if you purchased TPC once, you are entitled to update your program or not. We leave that up to you and we never tell you you’re out of luck. We don’t run your business; we just want to help you succeed in it!
We offer three Editions so you can choose the one that best suits your needs. Buy the program, and it is yours forever! If you want the full meal deal, get the TPC Connection membership! We doubt you’ll regret it.
