Released, September 29th, 2021

This release is all about things our users have asked for.

**Rich Text**

We added a new Rich Text object

- individual words and phrases can be underline,
~~strikethrough~~,**bold**,*italics*, different fonts and colors - any combination works
- import / export RTF to CAD via MTEXT
- copy boiler plate text from your favorite word processor and paste it into TPC’s drawings

**Traverse Direct-Reverse Report**

This report looks at each angle set in a traverse and tells you

- which ones have errors
- the means for each set when multiple sets are used
- apply angle set limits or Least Squares estimates of standard error

**Least Squares Modernization**

We just made LSQ easier to use and more helpful in determining how to identify errors and improve solutions.

Adding estimates of standard error for coordinates to our aPriori dialog is a good example. Now you can easily add GNSS RTK stations that are not fixed, and weight them based on the distance from your survey project to their reference stations.

**Unit Text Height & Char Spacing**

TPC has supported unit height text for years in our support for CAD blocks. Now you can use it to more easily create your own drawing blocks in TPC or force a label like a street name to change proportionally with drawing scale changes.

Plus, you can now access character spacing and width factors for aligned text.

We’ve added a new Rich Text object to TPC’s Drawing View.

It allows you to mix-n-match standard word processing attributes or copy and paste text directly from your favorite word processor.

Of course, you can convert any existing text or text box to the new Rich Text object.

The Direct-Reverse Report gives you detailed information about angle sets showing all means and splits.

Use the report dialog shown here to show all angle sets or just the ones with errors.

### Least Squares Blunder Detection

You can use this report to help find blunders as you analyze a Least Squares solution. For sets reported with errors, you might choose to

- exclude them
- change (reduce) their weights
- accept them if their standard deviations are within limits

### Sets with Errors

In this report snippet, TPC is using the estimates of standard error (aPriori) values of the current Least Squares analysis so set the error limits. The vertical splits exceeded the aPriori estimates. So this is a set you might choose to exclude from the Least Squares analysis or apply another remedy you prefer.

Means: set 1

HA: 128°02'15", Diff 0°00'06", FD 128°02'18", FD± -0°00'03", FR 128°02'12", FR± 0°00'03"

ZA: 91°07'47", Diff 0°00'27", FD± -0°00'14", FR± 0°00'14"! exceeds limit 0°00'08"

SD: 251.59, Diff 0.00, FD± 0.00, FR± 0.00

### Modernization

Least Squares Modernization (5:26) Our goal is to make Least Squares easier to use, giving you better tools to evaluate solutions and improve your results. We first added Least Squares back in 2004 and a lot has changed since then about the way we survey.

- NEW – est. stand errors (aPriori) for coordinates – think GNSS RTK coordinates
- NEW – ! symbol identifies observations outside your stochastic model – these are the ones you will want to look at
- NEW – separate statistics like Average Standard Deviation for Horizontal and Vertical observations to help you look for errors
- NEW – user selectable confidence interval for ChiSquared test
- IMPROVED – use of current, more modern terms like Reference Standard Deviation instead of Estimate of Standard Error of Unit Weight.

### Ghilani Sample Surveys

Least Squares Sample Files (2:17) Example 16-1, Example 16-2 from adjustment computations, SPATICAL DATA ANALYSIS, 5th Edition, Ghilani 2010, Wiley & Sons We included two examples from Ghilani’s text.

- Example 16-1 is a traverse adjustment example that ties a terrestrial traverse into GNSS control points
- Example 16-2 is a network adjustment

### Ghilani Network Example

Least Squares Network Sample File (8:20) Least Squares Network, Example 16-2 from adjustment computations, SPATICAL DATA ANALYSIS, 5th Edition, Ghilani 2010, Wiley & Sons You’ll learn how to

- edit estimates of Standard Error for individual observations
- New! adjust a minimally constrained network that holds just one fixed point and a fixed azimuth
- New? use Components to isolate errors to coordinates vs horizontal, angles vs distance

### Unit Text

By default, all text used in a drawing has a fixed height in inches or mm depending on your survey units. Now, you can also specify the text height as drawing units.

This is the default for CAD, so all you CAD users will feel right at home with it.

In TPC, we primarily use unit text when we create reusable blocks we plan on resizing as needed when used. The units text can be the better option to making these blocks perform just the way you want.

### Character Spacing

Creating a Stamp with Unit Text (7:30)

When it comes to getting arc aligned text, like many of you use when creating a CAD block for your professional stamp, it’s important to get it just right.

TPC now exposes two parameters for arc aligned text that make this possible

- Char Spacing
- Width Factor

We’ve consolidated help topics, workflows, videos, recorded demos and lots more in our new unified help system.

Run it as a .chm file directly from Traverse PC, or use the web version in your favorite browser.

We just completed our VPAT – Voluntary Product Accessibility Template for 2021. You’ll find the link in Contact Us, under the Accessibility tab.

The VPAT is a check list of tools that help everyone, including those with disabilities, learn and use TPC Desktop. Here are some examples.

- Our embedded and linked videos include closed captioning so the hearing impaired can follow along
- Windows Narrator reads the highlighted traverse in the Traverse Manager so the visually impaired can select the right traverse
- Our website includes header and footer menus for consistent navigation

With more and more people using Traverse PC everyday, expanding and documenting TPC’s accessibility features just makes sense.

### Point Label Left / Right Center Alignment

When labeling points, you can now specify Center Left and Center Right. When combined with a rotation angle, you can easily get labels that are offset and perpendicular to any alignment.

### Point Symbols show Symbol Name and File Name

Tooltips and the Drawing Data Manager now show the symbol name and file name for point symbols.

See a symbol you used in a drawing and want to use it again? Just put the cursor over it and you’ll see the symbol name so you’ll know what it is.
