Least Squares Adjustments
THE TPC “Least Squares” ADVANTAGE -  Traverse PC raises the bar again with the most powerful Least Squares feature available today.  Since Least Squares is “fully integrated” into TPC Desktop there are no additional modules or concern about transferring the solution into your survey from some external source.  TPC Least Squares can Solve Resections, Adjust Traverses, Adjust A Network, provide Blunder Detection in your observed data and Report Positional Tolerances of adjusted coordinates. Analysis can be done on both 2D and 3D and TPC can limit the adjustment to just X/Y or do a complete X/Y/Z adjustment.  A 3D analysis can use vertical (or zenith) angles or vertical distance (elevation difference) along with HI/HT. Creating the network is as easy as selecting the traverses to include and pressing a button.  No other software makes it this easy.  TPC reduces the editing to just about nothing compared to StarNet which spends seemingly endless chapters on their file formats. The initial coordinates of any network adjustment are critical.  TPC makes it easy to build your control loops, balance angles or coordinates (optional) and then adjust using Least Squares.  The coordinate values of the survey prior to Least Squares become the initial coordinates of the network – it’s that simple. TPC’s point protection dovetails seamlessly with ‘Fixing’ positions in a least squares network.  This allows the survey points to interact with the network at a higher level. The whole process is visible including editing the network and reviewing the solution before it is applied to the survey. Lastly, and perhaps most importantly, the UNDO feature can let you start all over with no penalty.  Feel free to do your best and not be forced to settle because doing it over takes too much time. LEAST SQUARES NETWORK ADJUSTMENT - The Professional Edition allows you to analyze your survey and create a Least Squares Network.  You can analyze the entire survey or just selected traverses; solve the network then review it before applying the corrections to the survey.  LEAST SQUARES TRAVERSE ADJUSTMENT - Both the Professional and Premium Editions allow you to adjust a traverse using Least Squares.  Use the Blunder Detection tools to isolate bad data in the traverse or just report the positional tolerances. Blunder Detection - TPC can report observation and coordinate blunders it identifies during a Least Squares solution.  Once identified, you can exclude the offending observations or coordinates and compute a new solution or you can take whatever steps are necessary to correct the observation or coordinate, then compute a new solution. Positional tolerance - Positional tolerances define the radius of a circle about a theoretical point based on its distance to the nearest controlling station.  Positional tolerances are derived from a Least Squares solution that gives consideration to stations that control the positions of dependent stations.  Generally, these controlling stations are monuments of fixed legal position and the dependent stations are new monuments that are being set. Pre-analysis -  When you ‘Pre-Analyze’ a Least Squares solution, you want to see what the adjusted coordinates and observations are without actually applying them to your survey.  This step allows you to determine the strength of the Least Squares data and solution. When TPC solves a Least Squares network or traverse, it is doing the pre-analysis.  The survey is not actually updated until you choose to Adjust it with the Least Squares solution. reprocessing -  When you have more points to add to a survey that has already been adjusted by Least Squares or you have an updated position for one of your fixed control points, simply re-run or re-process the Least Squares solution.  “FOUR step” process -  We’ve simplified Least Squares down to four easy steps with one tab for each step in our Least Squares dialog box. Step 1 -  Analyze In this step TPC analyzes your survey data and builds a model that Least Squares can solve.  TPC considers protected points, traverses, extra field ties, control points, side shots, and so on.  You determine which traverses to consider and whether to do a 2-D or 3-D analysis then TPC does the rest. Once TPC has built the network, you can edit it.  You might want to fix certain points, exclude certain observations or edit precisions.  Once you have the network the way you want it, you can solve and evaluate it. Step 2 - Solve In this step you tell TPC to solve the network using Least Squares.  TPC computes the adjusted coordinates along with all the statistics for coordinates and observations.  Your survey is NOT affected during this step.  TPC assumes you will want to evaluate the solution before you update your survey. TPC reports the statistics associated with the network solution.  This information allows you to evaluate the strength of the adjustments.  If you find weak adjustments, you can edit the data and solve it again.  You can repeat the Edit – Solve – Evaluate steps as many times as needed to improve your Least Squares solution—the flexibility professional land surveyors need to get the very best possible solution.   Step 3 - Update Once you’re ready to accept the Least Squares solution into your survey, just tell TPC to update the survey points.  Your survey doesn’t care if the adjusted coordinates came from a Compass Rule adjustment or Least Squares.  The adjusted coordinates are all treated the same.  And, of course, you can always undo any adjustment at any time.         Step 4 - Report Once TPC has computed a least squares solution, you can include information about the solution in a report.

Dynamic Object Labels

Label any line or arc you add to a drawing just like you label survey lines now. We’ve added a new Object Labels tab to the Drawing Settings dialog where you specify how you want the lines labeled.  Then use the new label command to select the lines you want.  And these labels are dynamic - change a line length and the label updates automatically. You can even trim, extend or break a line and its label updates automatically.  Wow!  Talk about a great tool for laying out lots in a sub-division design.

Dynamic Offsets

Snap an offset line from a house corner perpendicular to a lot line, then move the house on the lot.  The Offset lines update automatically, remaining perpendicular to their respective lot line, even curves, and reporting the offset distances and bearing (optional) accordingly.  This can actually make drafting fun again. Dynamic Offsets can anchor to any drawing object.  Snap to the end of a line or the insert point of a symbol or whatever.  If that object moves, the offset moves with it, updating the label automatically.         Not sure which house corner is closest to the lot line?  Simply snap a Dynamic Offset to both corners and delete the one you don't need.  It doesn't get much easier than that. Plus, Dynamic Offsets are smart enough to look past the drawing objects into the survey data to anchor themselves to the actual survey point or survey line represented in the drawing.  Now, if you recompute the survey, rotate, translate or otherwise update the survey, the Dynamic Offsets update automatically, showing the new relationships between the offsets.

Dimension Command

Dimensions are used to label drawing objects like lines and arcs at an offset distance from the object itself. In the example shown here, we’ve dimensioned the outside diameter of a floor plan on a lot.         Dimension lines and labels are controlled by a new Dimensions page in the Drawing Settings dialog.  You can control the gap from the object, the arrow type and size, the dimension line type and width, etc.  Changing the settings changes all the dimensions in the drawing plus controls the properties of any new dimensions you add.  This helps keep your dimensions looking consistent.

Interior Angle Command

Now you can add interior angles and labels to your drawings.  An interior angle is really just a dimension object and is controlled by the drawing’s dimension settings. The radius of the arc is determined by where you click on the first line.  For a bigger radius arc, click farther away from the angle’s apex - it’s pretty simple.

Object Snap Mode

Turn on the Object Snap mode, then move the cursor to within ½ inch of the object you want to snap to and left click.  Quick View places a snap marker (a small bright circle) on the part of the object that is closest.  Now just left click and you’ve got the snap you want.  Want a different part of the object, just move the cursor and the snap object moves with you. You’ll want to use this to select points into a traverse or connect feature points on a map. You can even use Object Snap mode with other snap commands like Snap End or Snap Mid.  Just get close enough for the Object Snap Mode to mark the object and left click.  Quick View uses the nearest object and your snap command to give you just the results you want.

Snap Nearest Command

The new Snap Nearest command works like the Object Snap mode but for just one snap at a time. You might end up using it more than any other snap command because it shows the anchor point on the snap object and automatically knows when you are snapping the end of the object or its insert point or perpendicular to a line or whatever.

File Exchange

TDS raw file support -  The new Recon and Ranger use this ASCII data file for both conventional survey data and GPS.  It uses the same file format and syntax as the RW5 file, but adds many new records.  Traverse PC is committed to supporting the TDS data collectors that so many surveyors use for their field work. TRIMBLE TOTAL STATIONS -  We’ve added support for the popular Trimble 5600 series total stations.  This  is our first foray into the Trimble total station world, with more file formats to follow in future releases.

Extras

Offset to Line Dialog - Now tells you if the offset point is Left or Right of the line and whether or not it is behind the starting point of the line. More Quick View Variables - We’ve added variables for the survey name, client and the location.
