In MensorGIS Text Features are a special Type of Point Feature (Menu „Edit-Texts-Generate from ObjectClass“):


A special Functionality of MensorGIS are Basic Surveying Calculations (Menu „Surveying“):

  5. press „Save“ -> Point Created

  6. close the Window (OK)


Edit Attribute „Name“ of New Point
  1. Menu „Data - Attributes - change“

  2. select New Point of Arc Section -> Window „Attributes: Change“:

  3. enter Value „PP1“ for Attribute „Name“

  4. press Button „Save“ to store

  5. close the Window (OK)


Compute a Backwards Section
  1. Menu „Surveying - Backwards Section“ -> Window „Backwards Section“ is shown:

  2. press P1 -> select St. Paul and then type in Angle 65.7789 [gon]

  3. press PM -> select Trinity Church

  4. press P2 -> select Radio Tower and then type in Angle 47.5701 [gon]

  5. press „Calculate“ -> Section Point is at 32472101.788 / 5378309.988 (PPN)

  6. press „Save“ -> Point Created

  7. close the Window (OK)


Edit Attribute „Name“ of New Point
  1. Menu „Data - Attributes - change“

  2. select New Point of Backwards Section -> Window „Attributes: Change“:

  3. enter Value „PPN“ for Attribute „Name“

  4. press Button „Save“ to store

  5. close the Window (OK)


Visualize the Points' Names
  1. Menu „Edit - Texts - Generate from Object Class“ -> Window „Create Text“:

  2. select Object Class „* TrigoPoint“

  3. select Attribute „Name“

Compute two-sided Traverse
  1. Menu „Surveying - Traverse two-sided“ -> Window „Two-sided Traverse“ is shown:

  2. press P0 -> select TP3065

  3. press P1 -> select PP1 (Start of Traverse)

  4. press PN -> select PPN (End of Traverse)

  5. press PN+1 -> select Radio Tower

  6. type in Distances and Angles (there are 3 Distances between the Points and 4 Angles in the Points):

  7. press „Calculate“ -> 2 new Points (and the Traverse) get highlighted

  8. press „Save“ -> Points Created

  9. Remark: The Residues are about 1 Centimeter which is quite good.

  10. close the Window (OK)

Edit Attribute „Name“ of New Points
  1. Menu „Data - Attributes - change“

  2. select the left of the New Points of Traverse -> Window „Attributes: Change“:

  3. enter Value „PP2“ for Attribute „Name“

  4. press Button „Save“ to store

  5. select the right of the New Points of Traverse -> Window „Attributes: Change“:

  6. enter Value „PP3“ for Attribute „Name“

  7. press Button „Save“ to store

  8. close the Window (OK)


Visualize the Points' Names
  1. Menu „Edit - Texts - Generate from Object Class“ -> Window „Create Text“:

  2. select Object Class „* TrigoPoint“

  3. select Attribute „Name“

  4. select Color „Black“

  5. select Size „4“

  6. select Layer „1“

  7. press „Create Texts“

  8. close the Window (OK)


Develop Marked-Out Route
  1. Menu „Surveying - Marked-Out Route“ -> Window „Marked-Out Route“ is shown:

  2. choose Element Type "Straight", type in 233.05 [m] as Length and press „Register“ -> DataView shows first Entry; press „Reset“

  3. choose Element Type "Circle by Arc right", type in 1000 [m] as Radius and 576.36 [m] as Length and press „Register“ ; press „Reset“

  4. choose Element Type "Straight", type in 851.89 [m] as Length and press „Register“ ; press „Reset“

  5. choose Element Type "Circle by Arc left", type in 1000 [m] as Radius and 525.52 [m] as Length and press „Register“ ; press „Reset“

  6. choose Element Type "Straight", type in 75.27 [m] as Length and press „Register“ ; press „Reset“

  7. Now all five Elements are entered, so press „Calculate“ -> The Preview shows you a Sketch of the Marked-Out Route; The DataView gives the Lengths of the Elements and the whole Marked-Out Route (2262.090 [m]).

  8. As this Development uses a local Coordinate System, now we want to tranform the Main Points of the Route's Axis into our current Project Dataset.

  9. Under Point1 choose "0", press Button „Pick P1“ and in the MensorGIS Main Window click on Point PP2 -> "8" should appear in the Button

  10. Under Point2 choose "5", press Button „Pick P2“ and in the MensorGIS Main Window click on Point PP3 -> "9" should appear in the Button

  11. Now the Identical Points are matched, so press Button „Transform“ -> Message "Trafo successful!" should appear.

  12. Remark: The Scaling Factor of m = 1.000016608 indicates that the Transformation nearly doesn't change the Route's Scale - as it should be.

  13. Have a look at the MensorGIS Main Window: the Main Points of the Marked-Out Route have been saved into the current Project Dataset.

  14. Tip: Press Button „Redraw“ to refresh the Sketch of the Marked-Out Route if necessary.
