Have you signed up for tomorrow's Power Hour? We'll be talking about Network and Traverse Adjustments in TBC, when and how to use each approach, and working through data sets to showcase each routine.

 

Check out more details here:

Bet you didn’t know about this week’s TBC tip!  You can enter azimuths into any angle control box and automatically change them to the corresponding bearing value.  This is very useful for speeding up key-in of cadastral map data.  The image below shows a typical angle control, in this case, in the CreateCOGO command window.  You can find the angle control in various other commands throughout TBC.

 

 

To change an entered azimuth value to bearing simply enter a "1" followed by a space, and then the azimuth value.  See image below for an example of this.

 

 

Once the azimuth has been entered and you have moved to the next line the value automatically updates to the corresponding bearing.  In the CreateCOGO command, this also updates the line command box shown below with the same bearing value.

 

 

 

*The correct bearing will always be computed, if you type 1 and then a space for any azimuth entered.

his is another tool in your TBC toolbox for being more efficient and getting the job done faster!

 

Happy Surveying,

This week we are exploring the right-click mouse button in TBC.  There are many reasons why it is useful to know what this button can do for you especially the time you can save.  

 

The primary function of the right-click mouse button in TBC is to allow quick access to many of the commonly used commands.  By right-clicking in the plan, 3D, station, or cutting plane view will open the right-click Context Menu.  See the image below for a description of the Context Menu and it's functions.

 

 

 

The Context Menu can be used with any selection of objects or when no selection is made.  In this example, I have selected a point cloud region in TBC and opened the Context Menu.  

 

Users can change the amount of commands displayed in the Recent Commands group by accessing the Project Options.  See images below for location.

 

 

 

 

Several new groups are available when using the Context Menu during a command operation.  The image below shows the various shortcuts available while using the Create Linestring command.  The quick access run commands are available in this menu to remove the need to navigate back to the Command Pane window while running the command.  Now you can focus on the current object and workflow with ease.

 

 

Don't forget to send us your Tip of the Week recommendations and until next week, happy surveying!

Using TBC to troubleshoot your field surveys is like detective work. Wondering how a specific point location got computed? Looking at the point properties doesn’t tell you much about the point info? In that case the tip below will be very useful. Point Derivation Report will be your best friend.

In this example, there is traverse, static GNSS, and differential leveling observations for establishing a survey control network.  Point 1011’s coordinates are calculated by all three observation types followed by a network adjusted value.

To create the Point Derivation Report select and right-click to view the shortcut menu and press Point Derivation Report.  You can generate multiple reports by selecting several points before running the report command.

The Point Derivation Report created from TBC is in HTML format and will be opened in your selected browser.

There are several elements to this report:

  1. The first section details the survey data and comparison of the calculated position values for each observation and coordinate

  2. The second section shows the calculated GNSS vector length and precisions
  3. The next section shows the terrestrial observations (total station) and their components

  4. This section describes the leveling observations used to calculate the elevation value for the selected point

  5. Finally, this section describes any effice entered, imported, or adjusted coordinates used in the calculations

 

Here is an example where this report can be used to find errors in a survey.  The observation in red is outside of the computation tolerances set in the Project Settings.  This information can be used to fix blunders by enabling/disabling observations, changing point ID's, and other raw information.

 

 

The Point Derivation Report can help you find all those pesky survey errors and clean up survey data to make a error proof deliverable.  Until next time, happy surveying!

Hi TBC Community - next Power Hour is set!

 

Register today! Fresh off our highest-ever attended (more than 1300!) Power Hour session in July, let's keep the momentum going! Register today for August 30th's Power Hour - Network Adjustment vs. Traverse Adjustment. This power hour will discuss the differences between the two and when and how to utilize in TBC.
