• Three Unique Types of Codes (Point, Line, and Area)

• Field Preparation Starting in the Office– Topcon Support Site

– Global Feature Code Library (XML File Format)

• Importing a Code Library into TopSURV

• Declaring a Global Code Library for Future Jobs

• Using Descriptor Codes

• Creating a New Code in a TopSURV Job

• Generating Code Driven Line Work

• Edit Existing Line Work

• Exporting Line Work in Multiple Formats from TopSURV

• Visualize Field Work in Topcon Tools and Export


Agenda

August 2009

• Point – treated as individual observations. Will be shown with defined point symbol, layer, and color.

• Line – instantly makes available a String Identifier field. Points that have the same Code and String Identifier will be “strung” together as line work in real time.

• Area – same as Line. However after three points, TopSURV will automatically and constantly close the figure.


Three Unique Types of Codes• When creating a descriptor code in TopSURV, you have the option of

declaring a feature type of either Point, Line, or Area.

• To take full advantage of automatic line work functionality within TopSURV, it is efficient (and more common) to stop and create / standardize on a Code Library prior to going to the field.

• Two common scenarios are to:– Create a new Code Library

– Use an existing Code Library

Field Preparation

August 2009


Field Preparation

• Whereas, if a company already has existing CAD Standards (most common), the goal will be to either convert to an XML format or create manually once in either TopSURV for Personal Computer, Topcon Tools, or SurveyMaster.

• In the case of creating a new Code Library from scratch, the Global Feature CodeXML file available from the Topcon Support site is great starting point.

August 2009


• The Code Library is now standardized between office CAD Standards and field data collection software…a bridge of efficiency.

Standardization Between Field and Office

August 2009


• To streamline routine work flows, it is common to declare that the Code Library XML file be used for all future TopSURV field jobs.

• Tap the Configure icon and select Global.

• Within the Code File field, tap the Browse button.

August 2009


• Navigate to and select the XML file TopSURVCodes.

• All codes, attributes, full descriptions, layers, line types, colors, and point symbols will automatically be standardized in all future TopSURV jobs on that field controller.


August 2009


• To pause and verify that this global declaration performs as expected, it is as easy as quickly making a new TopSURV and checking that all codes are automatically available for data collection.

• From the main menu, tap the Job icon and select New Job to create an empty job.

• Declare a job name and tap the Finish button.

Any questions?

August 2009


• From the TopSURV main menu, go to Survey / Topo to begin collecting data.

• Tap the down arrow within the Code pull down menu to see a listing of all descriptor codes currently available within the TopSURV job.

Using Descriptor Codes

1/17/2012

11

August 2009


• TopSURV will display all descriptor codes available within that job.

• Along with the functional Code name, you will also see a Full Description.

• For example, the Code of CP is also further described as Control Point.


August 2009


• Notice that the icon to the left of the Code field changes graphically depending on the type of code that is selected (Point, Line, or Area).

• Once a Code of either a Line or Area type is selected, the String Identifier field is instantly made available to begin “stringing” points together as line work in real time.

August 2009


• In cases where a new code is declared while in the field, TopSURV offers an immediate opportunity to fully define and add to the job’s Code Library.

Create a New Code in a TopSURV Job

August 2009


• Working your way down the Code screen, you can add a Full Description, Feature Type (Point, Line, or Area), Layer, Color, and Point Symbol.

• With this new code fully defined and now added to your job’s Code Library, you have the opportunity to export from TopSURV back to the office.

August 2009


• To begin generating code driven line work, simply select an existing code that is defined to be either an Area or Line feature type. For example, use the Code of EP – Edge of Pavement.

• The String Identifier field will instantly appear.

Generate Code Driven Line Work

String Identifier

August 2009


• For this example, the code of EP and string identifier of 1 will be used.

• TopSURV will “string” points together with line work so long as they have the same Code and String Identifier.

August 2009


• To easily draw smooth curves, rectangles, and closed figures, tap the Attribute Button.

• Within the Control Code pull down menu, you have options for:


Attribute Button

AS = Arc Start

AE = Arc End

R = Rectangle

C = Close the Figure

August 2009


• We now have layered points, lines, curves, and areas in defined colors and line types that can be exported in a variety of file formats.

Code Library Usage


• By starting out in the office and compiling a Code Library (once), many doors open while in the field with TopSURV.

• With little to no extra effort, all field data is now collected on the same layers, with the same point symbols and colors, and same line types as in the office.

• This now becomes effective communication between field and office teams.

August 2009


• However, a mistake was made in the field. The last point collected was assigned the wrong string identifier.

• Instead of 1, the last point shot on the back of curb (number 110) mistakenly has a String Identifier of 2.

• Therefore, line work is not connected to this ending point.

Edit Existing Line Work• In this example,

sequential shots were taken along the same Back of Curb.

• Therefore, they have the common Code of BOC and all have the same String Identifier of 1.

August 2009


• Rather than taking another shot and overwriting the existing point numbered 110, you have the easier option of simply correcting the String Identifier.

• Tap the Context Menu (Topcon logo at top left) and select Edit Points.

Edit Existing Line Work

August 2009


• However it’s String Identifier is incorrectly entered as 2. It should be 1.

• To fix, select point number 110 and tap the Edit button.

Edit Existing Line Work• Notice that the point

numbered 110 has a code of BOC like the other points measured prior to it.

• It was taken along the same back of curb.

1/17/2012

17

August 2009


• To edit the existing line work in your TopSURV job, it is as easy as changing the incorrect String Identifier from 2 to 1 and tapping the OK button.

• The points list will now show the change that you have made.


August 2009


• By tapping the Close button, you will instantly return to the Topo screen to resume data collection in the field.

• Notice that the job’s line work was automatically updated.

• The existing back of curb line work now correctly ends at point numbered 110 with a simple edit of an existing point.
